I had my first swarm in early May and missed it. The second one I caught as it landed conveniently on a near by bush.
I split my two strongest colonies on the 6th of May. They seem to be doing well as far as I can tell from the outside. I moved the queen and three of four frames of brood and stores into new hives and took them to an out apiary. I checked them two days ago and the queen had laid in all the brood combs. Hopefully this brood will hatch and be ready for the flow although it looks like the flow will be early this year. I notice the bramble flowering already and the clover not far behind so we are going to have an early flow and no noticeable June Gap, I suspect.
I have left the other two hives, (the ones with no queens) alone and I hope there is a new queen and that she is laying by now. I will give them another few days before checking them.
The great thing about the split hives is that you can forget about them and have only minor worries about swarming. The rest of my hives, I am watching trying to work out what is happening and never sure!
Give Drones a Chance!
I am still inclined to cut out drone brood as a way of controlling varroa. Varroa prefer drone brood because of their longer pupation time allows the varroa an extra brood cycle. Because of this many drones will tend to be under nourished and hence under developed and probably carrying a heavy viral load – it is not hard to understand why queens may not be mated properly.
We need to encourage drone brood and it is not a bad idea to put some drone brood foundation in each hive or to put a short strip of foundation in a frame allowing the bees to build their own drone brood.
We need to improve our drone stock or we will continue to have poorly mated queens. Poorly mated queens will fail in the first year or over winter and some will become drone layers. Try and give drones a chance and go easy cutting out the drone brood – there is some evidence that more drone brood improves temperament and can reduce swarming
Jobs for June
Make sure the bees have access to a plentiful supply of water.
Regular colony inspections with swarm management as required
Check for signs of disease especially varroa.
Monitor food stores and feed if necessary – can have the ‘June Gap’.
Add supers.
Queen rearing may be undertaken.
Lavender 
The lavender I bought and planted last year is in flower. The bees love it but bumble bees seem to love it more. There is research which explains this – some types lavender have flowers whose tubes are too deep for honey bees – e.g. ‘Grosso’, a type of lavender has flowers with tubes 7.5mm deep. Bumblebees have longer tongues than honey bees. Bees whose tongue is 6.7mm in length requires more open and shallower flowers for their foraging.
Lavender has been shown to have calming effects on angry bees. The research involved exposing honey bees to different odours while a  rotating feathery object to agitate the insects.  As expected the bees stung the feathery object. Yet when exposed to lavender even in combination with the sting-alarm pheromone and with the feathery object brushing them the bees did not attack.
A French research team tested these results in the field applying odours to the front of beehives ..the calming odours reduced the aggressiveness of the bees even though they had been agitated by a jiggling flag at the hive entrance. Maybe we should take to wearing a sprig of lavender when working with the bees.
Over last 20 years there has been a lot of interest in treating bee diseases with herbal extracts not just thymol but also laurel, mint, lavender etc.  oils. A Spanish researcher into the effectiveness of the essential oils of lavender, laurel and thymol in killing varroa mites gave claims that, ‘all essential oils cause mite mortality without sever harm to the bees. The old advice to add a tiny drop of thymol to syrup feed has been validated by research….

‘The absence of sadness may create bitterness. This saying is illustrated in the tale of the bee. After a long winter, she found a flower-bed. Three days later, the bee exclaimed : ‘I cannot think what has happened to this nectar, it has become so sour.’
The first bit of good news is that all my colonies have survived the winter and now, as April brings forth a burst of blossom, the bees are busily working hard to harvest lots of pollen and nectar. The dandelion has yielded well and my hives are now stocked with new pollen and honey.
I opened my hives on the 22nd March. I am glad I did as they were so full of ivy honey that the queens were restricted in their laying. I removed about three brood frames from some hives and have replaced them with frames of foundation.
When you get a chance to examine your colonies make sure the temperature is around 14 degrees and don’t spend too long at it and close up quickly. While manipulating try to cultivate a calm, deliberate gentleness avoiding all jarring and crushing of bees – crushing a bee will set off the alarm signals  from the scent of the sting venom. Try to establish a routine for opening a colony eg. put each hive part in a set place etc.
If the temperature goes down, and it can do so quickly at this time of the year, the brood can get  chilled – so short quick inspections are best. Use Hooper’s five questions and try and mark the queen.
Hoopers’s five questions:
1. Room  have they enough room
2. Eggs – is the queen present and laying
3. Development – is colony building up as fast as other colonies – queen cells present?
4. Disease – varroa mites?
5. Stores.. Enough till next inspection?
Always keep an eye on the outside of the hive – note how the bees are behaving. Bees are constantly giving us messages and if you become familiar with their behaviour you will learn a lot. If you have mesh floor boards you may notice wax pieces falling through onto the ground telling you that they are chewing their way through stores and seem to be healthy and well.
Don’t forget to make sure there is good supply of accessible water for them – bees need lots of water in the spring especially if they are to break down crystallised ivy stores .  It is a good idea to set up a water source in the sun so that it is warm for them. Bees prefer collecting from a shallow place as the water warms more quickly – you can use containers filled with peat or potting compost and topped up with water as they make landing easy for bees. A container filled with pebbles and water also works. Water shortage may not be something you would think of given that we have so much of it – it is about making it accessible to bees. Also don’t place the water in the flight path of the bees as it could be contaminated.
Ivy honey is hard to deal with unless you have some people who like its particular taste. I have found a few such connoisseurs of honey and they will use all I have. I will keep some for feeding bees later in the year or when I split some colonies. Three or four of my colonies are very far ahead and bursting with bees. I had to give two of them a second super (they were wintered with one). These are good candidates for splitting and that is what I plan to do. I must set a date but obviously it can’t be done until we have drones on the wing to mate with the new queen when she is on the wing.
RECIPE
Using honey to treat Insomnia.
Honey can be used as a sedative. If falling asleep is difficult take a teaspoon of honey at your evening meal. Should sleeping problems continue try the following.
 2 teaspoons apple vinegar
 2 teaspoons of honey
 1 glass of water
Combine the ingredients and take 3 tablespoons at bedtime.
A friend of mine sent me a nice poem by Saint Thomas Moore on the virtues of growing rosemary.
As for Rosemary
I let it run all over my garden walls
Not only because my bees love it
But because ’tis the herb
Sacred to remembrance
And therefore friendship,
Whence a sprig of it hath a dumb language.
St. Thomas Moore

The Ass

‘I know that there will be clover when the weather improves,’ said the ass, ‘but I want it now. Everyone gets hay. How to solve the problem? I don’t know, I’m too busy thinking about the clover.’  

The heather is still flowering  in the Monastery Cloister Garden and the bees are enjoying it! The heathers we planted are as follows:

‘Kramer’s Red’ – dark foliage and dark red/purple flowers

‘Ghost Hills’ – pale green foliage with pink flowers

‘Perfect White’ – pale green foliage with white flowers

All varieties flower from winter through to late spring.

We are moving into the ‘busy- bee’ season. I am putting together nice new frames and will be adding foundation soon so I am ready for the new season. I am expecting to peek into the hives around Saint Patrick’s day and will make an assessment of how they are progressing. I just need a nice warm, sunny day!

I met a beekeeper up North last week who had already had a quick look inside his colonies. We discussed what tactic we might adopt this year to manage our colonies – would we clip and mark the queens or would we go for minimal intervention and see how it goes? Like good politicians, we didn’t reach any conclusion!  I am away for much of July so I may be forced into the minimal intervention solution.

My main reason to look into the colonies early is to ensure the queen has enough room to lay and that there is a queen laying. Many of the brood frames could still be full of ivy honey from the autumn. I will also check that they have enough stores.

While it is still cold and the propolis is hard, it is a good time to clean spare hive parts and recycle your frames for the coming season.  Put all floors, brood boxes, supers, crown boards, queen excluders and roofs in a to-do pile. I use a scraper hive tool and a blowtorch. You can clean and scrape all the bits into an upturned roof.

First scrape the inside surfaces, clean off brace comb and the propolis. Once you have removed most of the debris flame the inside surfaces and stop when the timber changes colour. The finished item will be clean and hopefully sterile (free of disease).If you have plastic runners this will be a problem. Using metal runners gets over this problem..

I read an interesting piece on foundation. Thorne, the bee equipment suppliers are now offering 4.9mm foundation for sale. I didn’t know there was such a thing as 4.9mm foundation.  This is as a result of a project carried out at Reading University.

They are studying varroa to see whether the use of smaller cell foundation (4.9mm) makes a difference. The investigation is being carried out with beekeepers in the local area as well as in the apiary at the university. The study will evaluate the use of small cell foundation  alongside  regular sized  (5.4mm) foundation and compare the varroa loads during next spring and summer.

Apparently beekeepers in other parts of the world have had success using this small cell foundation but many others have not. Some previous studies found that varroa counts increased in the short term when small cell foundation was first used. The new study will evaluate what happens once the bees have fully adjusted to small cell foundation and if there is a significant impact on varroa loads.  I will wait and see the results before changing my order of foundation.

BroodMinder – a new piece of kit which uses the latest technology and integrated circuit temperature and humidity chips to monitor your hive and it is not too expensive and seems easy to fit. It generated data every hour on the what is going on in the brood chamber. The idea is to reduce the need to open the hive. The data is sent to your smartphone or tablet. BroodMinder-W measure hive weight and outside temperature. Worth a look at broodminder.com.  Happy Beekeeping!

A story about disguise 
Once upon a time there was a bee who discovered that wasps didn’t know how to make honey. She thought she would go and tell them, but a wise bee said to her, “wasps do not like bees, and they will not listen to you if you approach them directly since they are convinced that bees are opposed to wasps”.
The bee thought about the problem for a long time and then realised that if he covered himself up with yellow pollen eh would look so much like a wasp that they would accept her as one of them.
Now, disguised as a wasp who had made this great discovery the bee started to teach the wasps about making honey. The wasps were delighted and worked hard under her direction.
Then there was a pause for rest and the wasps noticed that in the heat of the activity the disguise had worn off the bee and they recognised her..
With one accord they fell on her and stung her death as an interloper and ancient enemy: and the half made honey was abandoned…for was it not the work of an alien?
The bees have had a gentle winter so far and have managed to get out most days. On mild days they are working on the heather which is still flowering here. If the bees have had a gentle winter it means the varroa have too. There is a new study comparing the ability of two strains of bees to defend themselves against varroa by grooming – this is where bees brush mites from themselves or brush mites from their nest mates. It has been known for sometime that different strains of bee differ in their resistance to varroa. In particular Africanized bees  appear more resistant than European strains. Scientists have found that this resistance is partly due to grooming behaviour. This may be a step forward in the fight against varroa and finding bees resistant to varroa.
I am getting frames ready for the new season – scraping off excess wax and cleaning them up ready for new foundation. I am also scorching brood boxes and supers to try and ensure no disease survives in them.
ANOTHER PEST
There is news that the dreaded Asian Hornet has reached England and Wales. This is a new threat to the bees. We have no native hornets though the wasp is a close relative.
It arrived in Europe from China in 2004. It was first spotted in France and has since spread to Spain (2011) , Portugal and Italy and male hornets observed flying in Belgium in 2011/12.  It has now been found in the UK.
The worrying thing is that one to two thirds of its diet consists of bees.They have already devastated colonies of bees on the continent. They attack the colony by picking off individual bees as they return to the hive. When the colony is weakened a group of them attack and devour the bees and any stores that remain. It is predominantly black and brown with brown abdominal segments that are brokered with a fine yellow band. Only the 4th segment is almost entirely yellow/orange. Its legs are brown with yellow ends and the head is black with orange red face.The queen is about 30mm long and the workers about 25mm and their legs are yellow.

 

They make nests in trees and tructures such as garden sheds and garages. The nests have also been found closer to the ground and in basements. They avoid pure conifer stands and seem to prefer oak, populars and acacia trees.
ASIAN HORNET YEAR
They are active from April-November. In April the queen emerges from hibernation and the colony builds up to average population of 6000 individuals. They begin preying on bee colonies once the brood require animal protein. Drones are produced later in the season and queens mated in September.
Possible routes of it to Ireland
Imported wood and wood products, flowers – overwinter under bark. In soil, freight containers and transport vehicles.
WHAT TO DO? Remember they do sting!
In France traps work well especially in Spring and Autumn.
They use a mixture of dark beer, strawberry syrup and orange liqueur wine – others use set mixtures of wine, sugar and water. At the height of the season you can add high protein foods  such as fish.Notes on building a trap form two plastic litre bottles can be found at the National Bee Unit guidance notes on monitoring for Asian Hornets.
The ApiShiled trap. It is a modified base for the hive with a decoy entrance into a trap as well as the normal entrance for the bees – it works because the invaders choose to enter by the decoy entrance rather than face guard bees – this can also be used for robber bees, and wasps. It works by ‘teaching’ the colony to use the front  entry and then opening the  decoy entrance at the side which fool the predators and trap them below the real floor…
Watch out for it- if it arrives it will have potentially dramatic consequences for changing the structure of insect communities and adding further pressure on our already beleaguered  honey bee population.
If you find one report to the National Biodiversity Data Centre  with a photo. Can kill by placing in a freezer over night.
THE THREE ‘F’s
1. Forage – essential to have pollen source available all year round – need up to 200 pounds per year! 10-12mg per bee. Winter flowering heather useful plant.
2. Feed – whenever needed. As thick as possible 2 kilos to 1 litre or 3 kilos to 2 litres. Apiinvert or ambrosia best type of sugar…check for it online!
Put fondant over cluster in Feb – leave in plastic container or cover with cling film to prevent it drying out. Can cut 2.5 kilo bag in to 3 or 4. Can spray with warm water to melt. Warm moisture from cluster will also help to soften.
3. Frames only use premium wax. Economy wax is a mixture of waxes.
Glue together – tacks corrode and frames can come apart. Evostick weather proof glue. Glue top bar and uprights and also the bottom bar opposite the piece you remove….. and tack as well.
DEAD HIVES
If you find a dead hive in the apiary and it is very possible during the winter, it is best to remove it immediately and scrape off all dead brood. You can fumigate the brood box using  80% glacial acetic acid. 100 ml per brood box. You can put acetic acid glacial in a bowl and soak it up with a cloth and place on brood box.
BIOLOGY LESSON
And now for a biology lesson! I marvel at the number of glands this small creature has in its body –  we should be familiar with at least some of these, especially the Nasonov, wax and sting glands.
Hypopharyngeal glands
One on each side of head. Found in young bees and used to produce brood food and royal jelly.
Nasonov gland
Found on the abdomen and releases a pheromone or ‘come join us’ scent. It This attracts bees to a swarm, marks a water source and foraging sources as well as the hive entrance. It is also used to call the queen back after mating and stragglers back into their hive.
Wax glands
Four pairs found on abdomen. Produce wax for capping cells and making cells.
Tarsal glands (Arnhart)
Six of them on each leg. Produce oily substance which leaves a footprint odour on flowers visited.
Sting scent gland 
Found in the sting chamber in abdomen. Puts bees into attack mode and provokes stinging.
Sting alkaline gland or Dufour gland
Produces alkaline liquid which lubricates the sting mechanism and neutralises excess acid.
Sting acid gland or venom gland 
Produces venom
Mandibular glands
Two each side of head above the mandibles.
In young bee produce 10 hyroxydec -2-enoic acid the principal fatty acid of brood food and royal jelly. In older worker 2-heptonaone – alarm pheromone to warn intruders. 2 -hepatanone is also an anaesthetic delivered on biting.
Post cerebral glands behind the brain and thoracic glands – two of them in thorax.
Together form salivary glands and they produce a liquid to lubricate food in the proboscis and the pharynx. It also contains invertase to convert sucrose to glucose and fructose.

Happy New Year. I hope it is a good year for the bees not just in terms of honey production but more importantly in terms of bee health and reproduction.  I see the hazel catkins are already well extended an encouraging sign but also a bit alarming that it is happening so early in the year.
The day I posted the December notes, I was riding my bike and round a corner I was surprised by the strong scent of ivy blossom. It was truly the last vestige of autumn.
The 7th of December, was the feast of St Ambrose, the patron Saint of Beekeepers and it was so mild the bees were flying hard and I got stung. They were working on a heather bed which is in full bloom. Two polystyrene hives were going flat out and the apiary sounded more like it was high summer. It was good to see activity at every hive and pollen loads arriving frequently. The bees are also working on Mahonia x media outside the library. I think I have the right name for that yellow flowering plant.
Since the bees require minimal attention at this time of year,  it gives us a chance to get equipment ready for the coming year – clean old frames and have them ready to be waxed up in the spring.  It is also a chance to catch up on reading those bee books that have accumulated during the year.
FOOD SUPPLEMENTS
HiveAlive is a supplementary feed developed for bees. It has been the subject of recent research and has received high praise.  It was developed by Dara Scott in NUI Galway in collaboration with other researchers and beekeepers and is  a blend of Irish seaweed extracts which have anti-microbial, anti-viral anti-fungal and immune boosting properties as well as high levels of vitamins and minerals.
The research suggests, that if used annually, it leads to an increase in population and to a quicker build up of colonies in the Spring. I have used it for the last two years and it seems to work.
It is said to have two other benefits:  first it prevents syrup from fermenting which is handy if you want to keep syrup for  a while and secondly brushing foundation with syrup that has HiveAlive in it  seems to encourage bees to draw it out.
WINTER CLUSTER
Bees work to beat the winter cold by forming a cluster which can contain as many as 20,000 bees. They move to the centre in shifts and eat honey from the combs and using the energy generated to flex their wing muscles and create heat. The queen is protected at the innermost area
NEW YEAR.
In my experience New Year’s resolutions rarely stick – we are too fixed in the familiar patterns we create for ourselves.
I like the idea of taking up mono-tasking even if it only while beekeeping. I am a self-confessed multi-tasker – on the phone, answering emails, reading a snippet from a book, all at the same time  – flipping from task to task trying to get as much done as possible. The result is usually that none of the tasks get done particularly well and leave little satisfaction in their wake.  Mono tasking is committing to focus on one task at a time. I know it would be good practice, both for my physical and mental health to slow down and stop overloading my system and be fully present to one task….
There is a piece of research carried out at the University of London which suggests that multitasking can cause a dip in your IQ!
HOT TODDY CURE
One of the main ways to fight a cold is to get plenty of rest. For generations people have also taken a hot toddy to ease the aches and pains of the common cold and with good reason. The alcohol helps fight infection and discourages the growth of microorganisms. Whiskey is a great decongestant  -the alcohol dilates the blood vessels making easier for mucus membranes to deal with infection – and combined with the squeeze of lemon, honey and the warm steam emanating form the drink, you have the perfect concoction for helping clear up your cold symptoms….and it also makes you groggy  and sleep comes more readily.
WORKING IN A BEEHIVE!
How do bees allocate their jobs for the day?  There is no obvious foreman or manager.  Some form of self-organisation occurs resulting from interaction between bees who are working. Each bee responds to local knowledge..
We know that ants leave a trail of chemicals when they find a source of food – other ants follow the chemical trail to the food.
Some ants also laid down pheromones while they searched for food. Scientists placed a bridge between a tub containing a colony of ants one containing food. A quarter way across the bridge it split into two branches – both led to the food but one path was twice as long as the other. The ants quickly worked out which was shortest
The pheromone trail was key – as more ants picked the shorter route it accumulated more and more pheromone increasing the likelihood that other ants would choose it!  Two ants set out across the bridge at the same time. The first takes the shorter branch and the second the longer one. By the time the first ant reaches the food the second is only half way across the bridge. By the time the first ant returns to the colony  the second ant has just arrived at the food. To a third ant standing at the split in the bridge at the point, the pheromone trail left by the first ant would be twice as strong as that left by the second ( the first went out and returned)  making it more likely to take the shorter branch!
The more this happens the stronger the pheromone trail grows and the more ants follow it.  This self-organisation means they don’t need a foreman telling them what to do. Perhaps there is a similar mechanism at work with bees.

Here’s hoping that all our hives will be healthy, strong and productive during 2017.

Thou art a miser, thou busy, busy Bee!

Late and early at employ;

Still on the golden stores intent,

Thy summer in heaping and hoarding is spent,

What they winter will never enjoy;

Wise lesson this for me, thou busy, busy Bee!

 

Little dost thou think, thou busy, busy Bee!

What is the end of thy toil.

When the latest flowers of the ivy are gone,

And all thy work for the year is done,

Rhymester comes for the spoil.

Woe then for thee, thou busy, busy Bee. 

Robert Southey.

The ivy flowers are gone and with them that wonderful pungent scent that surprises me round so many corners. So we are into December – the quiet month in the apiary. There is little to be done except to check that the hives are upright and water tight with no leaks. Bees can survive temperatures as low as -39 degrees celsius but dampness will kill them. The mesh floor has reduced dampness in hives. Make sure you have entrance blocks in place too..

At this time of year there will be little or no sealed brood in the hives, consequently the vast majority of

varroa mites will be on the adult bees. Some people spray these adult mites during the winter. I have not tried this method.

Frosty weather makes wax brittle and easier to remove – it is a good idea to leave queen excluders and frames outside for a short while as they are easier to clean.

Last month I bought two lavender plants to place near the bee house. During the summer, while visiting some friends in the UK, I noticed bees working enthusiastically on lavender and I was determined to plant some to supplement the diet of my bees even if just in very small way.

I have just read about the Chinese Bee-Bee Tree (Tetradium daniellii) which flowers in the late summer providing a useful supply of nectar and pollen just when most plants are dying away. They have white flowers which give off a beautiful scent.  It grows to a height of 15 meters and prefers the sun and is not picky about the soil as long as it doesn’t get too dry.

IVY

The influx of pollen in the autumn is vital to ensure good, healthy winter bees. The great flow of nectar and pollen from ivy this autumn should mean that colonies will overwinter well.

STORING SUPERS

Supers should be stored away undercover ensuring that the stacks are bee-proof with two layers of newspaper between each super. If supers are wet the wax moth wont touch them. The moth also finds it difficult to break through the newspaper layers

WINTER STRATEGY

Insects are cold blooded and most do not survive the winter and die once the weather gets cold. Most species survive by either leaving a queen to overwinter or an egg to hatch out the following spring. Insects that live as a colony through the winter have to make elaborate preparations to do so.  Preparation starts in early autumn as the days shorten and the temperature drops. The drones are evicted and the numbers of workers is reduced and stocks of honey and pollen are in place. Winter worker bees build up a store of carbohydrate, protein and fat in the form of fat bodies. Their main job of these winter bees is to get the cluster (and its queen) safely through the winter – they have to maintain a minimum cluster temperature of 8-10 degrees celsius at the surface and 34-35 degrees at the centre of the cluster if winter brood is present. Heat production by the inner bees and insulation by the outer bees allows this temperature to be maintained. A healthy, well stocked colony in the autumn should see winter bees live on into mid-February. Diseases tend to shorten the life of the winter bees and therefore of the colony. Lets hope our colonies have good healthy winter bees.

PATRON SAINT St Ambrose Patron Saint of Beekeepers.

His feast day is on the 7th of December.  He was bishop of Milan in the second century and has been venerated as the patron of beekeepers for many centuries. He is often depicted with bees. There is a story recounted by St Paulinus that a swarm of bees settled on the mouth of the infant Ambrose and then departed leaving the child unharmed. This led to Ambrose being called ‘honey-tongued’ as he was famous for his rhetoric.

BURY ME WITH HONEY!

When Alexander the Great was killed his body was placed in a gold coffin filled with honey for transport home.  In England the first four Earls of Southhampton were buried in honey filled coffins – honey that was still free flowing and sweet according to the workmen who excavated the containers and sampled the contents centuries later – before discovering what lay in side.

MOBILE PHONE

It may be important to leave your mobile behind when working with bees.  A new study by Swiss Federal Institute of Technology has concluded that cellular phone calls disrupt vital honeybee communication signal – known as ‘worker piping’, causing the bees to become terminally confused and die.

DANGERS OF MANUKA HONEY – TOO VALUABLE!

I was sent the following article on the problems facing manuka honey producers in New Zealand.

It was the day the bees died – tens of thousands of them in 300 hives, mysteriously killed. “The massacre”, as it is being called, happened in the otherwise idyllic landscape of Doubtless Bay in New Zealand’s far north.

And for David Yanke and Rachel Kearney, co-owners of Daykel Apiaries, the cause of death was obvious: malicious poisoning.“It is a nightmare, I don’t feel safe any more,” says Kearney as she sits at her kitchen table on her family’s farm, 40km east of the Northland hub of Kaitaia. “I feel violated. It has almost turned into a PTSD [post-traumatic stress disorder] experience for me.”

So far there has been no official ruling on what led to the Daykel bees’ demise, although a biosecurity incident has been ruled out by the government. But Daykel and many other apiarists are in no doubt that the mass bee death is just the latest act of violence in the increasingly crime-ridden manuka honey industry. The global craze for manuka, highly valued for its medicinal properties, has created a gold rush in rural New Zealand that some believe is rapidly spiralling out of control.

Last year a record amount of nearly 20,000 tonnes of honey was produced, a 15% increase on the year before. In 2010 the top price fetched for bulk manuka honey was NZ$37.50/kg (£22/kg) – today it can command more than NZ$100/kg. The export market to the UK, China and other countries is expected to reach NZ$400m in the next few years.

On the back of the boom, hive thefts, vandalism and poisonings have become standard fare, with every beekeeper interviewed for this article the victim of one or more serious crimes. Verbal threats and physical beatings have also been reported and there are unconfirmed reports that beekeepers now travel in packs for protection to work remote hives.

Manuka is a native New Zealand plant, whose potent pink and white flowers have made the once maligned weed a sought-after crop. The honey produced by bees who feed on those flowers has become highly valued for its medicinal properties, especially as a salve or wound dressing.

Positioning honey hives close to the plants means beekeepers can market their honey as “manuka” and sell it for triple the price of standard clover honey, even if the active manuka content is so low as to be negligible.

Supplementary feeding on sugar syrup, which used to be rare, has become a necessity for every apiarist and there is dark side of which Yanke and Kearney have come to know intimately.

Only months after they had buried the corpses of their bees, the midnight raids began. Farm gates were cut open with cordless tools, hives dumped into plastic rubbish bags and tossed carelessly into the back of open trucks.

The couple have memorised every detail of the thefts, because they were captured on CCTV cameras, which were installed after the bee massacre.

The raids also always occurred on the fifth of the month – another clear indication that intimidation tactics were being used against the beekeepers.

“We want to get out of the industry,” says Yanke, a Canadian with an encyclopedic knowledge of bees. “We want to get out before things get worse.”

Bruce Robertson understands the pressures now bearing down on an industry that is being overwhelmed.

As the managing director of Haines Apiaries in Kaitaia he has watched the boom happen in front of his eyes.

Although Maori people had used manuka honey as a wound dressing for years, the apiculture industry was wary of the product, as it was tricky to work with, had a short flowering season and somewhat bitter taste.

“I got into the industry when manuka was selling for NZ$10/kg and we thought that was an incredible price,” recalls Robertson, a no-nonsense, old-school beekeeper. “Now it is commanding up to NZ$200 at the high-end – it has gone really stupid.”

Robertson has become somewhat hardened to the scale and frequency of attacks on his 3,000 hives. Over the past five years, he’s had hives stolen, vandalised and poisoned, and estimates three to four are pinched every week, at a cost of NZ$3,000-4,000.

Happy Christmas and if you happen to get a present of some manuka honey, spare a thought for the producers.

Ivy has given us a bumper crop this autumn. And wonderful autumnal colours have surrounded us. I love the strong, distinctive scent of ivy in flower. It surprises you as you round many a corner. Out on my bike I suddenly come upon a corridor of scent laden air. We have a garden and the walls are covered in ivy which is not good for the walls but great for the bees.
The flow was so strong at the beginning of October that some of my coloniees were running out of storage space. I gave the three strongest hives a super. This is something I have never done before at this time of year. Most hives are now very heavy when I heft them from behind and from the sides. What to do next? The issue with ivy honey is that it sets hard very quickly. It is difficult for the bees to use it in a cold winter as they need water to dilute it – if it is too cold they may not be able to get the water and could die in the mids of plenty.
I have removed two supers of ivy honey. It is absolutely white and rock hard as it has crystallised.  I have warmed  it to soften it a little and eating it in the comb. It has a unique flavour which is not to everyone’s liking. I may try to heat some of it and press the honey out.
As I write at the beginning of November, there is still some ivy nectar and pollen coming in.
Bees and caterpillars
An interesting story appeared in An Beachaire reminding us of the complex relations that exist in nature. There are indirect interactions between species of a food web. One such is the connection between bees and caterpillars – we now know that bees or wasps flying around vegetation significantly reduces plants being eaten by caterpillars.
Wasps often eat caterpillars and create air vibrations with their wings that stimulate the sensory hairs on caterpillars.  To avoid wasps the caterpillars stop moving and often drop off the plant. Flying bees produce similar air disturbance that also stimulates the sensory hairs found on caterpillar causing them to drop off the plant. This defensive behaviours triggered by airborne vibration reduces  caterpillar activity.Bees not only transport pollen from flower to flower but in addition reduce plant destruction by hungty caterpillars!
Urban bees v Country Bees
The interest in urban beekeeping continues to grow. Many cities now have substantial hive populations including Paris  in the Luxemburg Gardens.  Bee keeping has been taught here since 1856! Jean Pucon who has looked after these bees for the last 25 years maintains that these bees in the  centre of Paris are healthier than the ones he keeps in the country…
Rural pollution by agricultural chemicals can make many rural areas toxic to bees. Recent studies show that even ‘wild’ areas close to agricultural lands may be heavily contaminated by chemicals that are applied to crops. These may have been transmitted through air or water or carried by pollinators.
In the future it may well be that urban sites will provide healthier apiary sites than the country.  The Ginza project in Tokyo Japan, claims that the bees are much less affected by the diesel and petrol fumes then they are by agricultural chemicals. Begun in 2006 by Seita Fujiwara, who was looking for a safe place to keep bees and 2009 he was producing 750Kg of honey in the highly polluted urban space of Tokyo according to the Japan Times. Fujiwara claims that roof top beekeeping in Tokyo is safer for his bees than farm land in his area.
Air pollution can be a problem for bees as high levels seem to interrupt scent trails which are vital for foraging pollinators. Researchers have found that the distances which pollinators detect flora scents may have diminished from several kilometres in pre-industiral times to less then 200m today in polluted conditions. This effects both plants and pollinators. Pollinators have to spend more time searching for plants and this decreases their efficiency.
Venom
Once again bee venom is being proposed as a treatment for arthritis sufferers. It is reported that scientists have developed tiny nanoparticles that can be injected straight into painful knees, using a peptide found in the insects’ poison.The peptide, called melittin, has a powerful anti-inflammatory effect that halts the destruction of cartilage, the body’s built-in ‘shock absorber’. Experts tested the jab on mice and now think that the sooner it is given after a sporting injury or accident, the less likely it is the joint will later develop osteoarthritis.
But they are also hopeful the bee venom particles will help those who have suffered the painful condition for years.

October was known as the ‘Yellow month’ by Roman slaves, from the fading of the leaf; to the Anglo- Saxons, it was known as Winter fylleth because of this moon (fylleth) winter was supposed to begin. 
October is the time when work winds down in the apiary. That said, I still keep a close eye on the hives.  If I have to open a colony I am far less invasive then earlier in the year. There is little reason to do an internal inspection other then to check for stores or that brood is present and the queen laying. There is always the alternatively of checking stores by hefting hives from the back and from the side.  One can always learn so much watching the front door of a hive – pollen coming indicates that the queen is present and laying.
Drones have should all been expelled by now. If you see drones at the front door especially during the second half of the month this needs to be investigated, as there could be something wrong with the queen. It could be that the colony is queen-less, in which case you will need to unite it with another queen right colony.
October is a good time to cut back hedges or trees which maybe shading the apiary. Fences and gates enclosing the apiary need to be made stock-proof. Hives should be checked to see that they are watertight and roofs are secure – I place a concrete block on most of mine.
The ivy seemed to  start flowering early this year. I noticed the bees working on it in while I was out walking as my attention was drawn to the distinctive scent of ivy in flower. Like all smells it is almost impossible to describe.  The small green flowers of ivy will go on flowering often till the first hard frost. The flowers produce an abundance of nectar and pollen.  Having access to this high-quality supply of nectar and pollen late on in the season improves the chances of successful over-wintering for colonies. PhD student Mihail Garbuzov, says: “In September and October ivy is the main game in town if you want nectar or pollen. Have a look for flowering ivy from mid-September to mid-October, when it is at its peak. On a sunny day you will be amazed at how many insects there are on it.”
Ivy honey sets very quickly and can be difficult for bees to use during the winter. I met someone recently who harvests ivy honey and that removes the problem. Ivy honey is said to have medicinal qualities and a very distinctive flavour.  Irish ivy honey has recently been shown to contain the compound ‘Hederacoside C’ which may explain its unique benefits.
I sorted my supers three weeks ago – into frames ready for cut comb and those only partially filled. My plan was to give these latter frames back to the bees and winter some of my colonies on a brood chamber and a half. I began the process but then made a serious mistake. I opened a small window to let some stray bees escape and forgot to shut it – the wasps and bees found their way in. I returned three days later by which time the room was a mass of bees and wasps – it was like a swarm had arrived and there was a large number of dead bees on the floor (ones that could not find the open window) but strangely very few dead wasps – wasps seem better at finding their way back out of such situations. The result is that I have lost a lot of bees don’t have any half filled supers to put on and will need to do some additional feeding.
I have removed the empty Apiguard trays and I hope the varroa numbers are down. Varroa can do huge damage to a colony in autumn as this is the time when winter bees are being produced. Winter bees are  physiologically distinct and hope they go into the winter unscathed by the blood sucking mites.  These reddish-brown parasites, just a dot to the naked eye, drain the life out of bees and worse, delivers a deadly cargo of viruses.
To get a sense of the size of a varroa mite in relation to a bee – make a fist and place it on your body. Proportionally, this is how large a varroa mite is compared to a honeybee’s body. It would be similar to having a parasitic rat on your body sucking your blood. If you have access to a microscope it is worth looking at a varroa mite: it is armoured and hairy, with eight legs and a piercing, sucking mouthpart. Since the parasite arrived in Ireland it has made beekeeping much harder.
I don’t know if you read the sad tale about the beekeepers in the  US losing millions of bees as  officials sprayed neurotoxins to kill mosquitos that carry the Zika virus.
A last word: A new study from the University of Cardiff School of Engineering  shows that the cells formed in wax don’t start out as hexagons but as circles. (Darwin suggested that but had no evidence) The cells gradually form into hexagons by the flow of the wax  which is rendered malleable by the heat from specialist heater bees. When it is warm enough the wax starts to flow as an elastic liquid and then it is pulled into  hexagonal cells by surface tension at the junctions where three walls join.

September – the seventh month of the Roman calendar. The Anglo-Saxons called it the gerst-monath or barley month.

“Best I love September’s yellow Morns of Dew strung gossamer, Thoughtful days without a stir; rooky clamours, brazen leaves, stubble dotted o’er with sheaves – more than Spring’s bright uncontrol  suit the autumn of my soul.” Alex Smith

What a year! I have taken off whatever honey there was- there wasn’t  much to take. The bees got so few opportunities to work – when they did get a fine day or may be two, they used up what they had stored t in the next week of bad weather. I actually found one hive close to starvation with no honey stores at all and had to feed them immediately. I found three colonies with no queen and have united them with a neighbouring colony. I  used two sheets of newspaper with pin pricks in them and the amalgamations have gone well.

Having removed the honey I am feeding a mix of sugar and water in the ratio of two parts sugar to one part water. It is helpful to spill a little syrup over the feed hole so the bees find the sugar more quickly but be careful not to let any drip outside the hive in case you start a robbing spree.  The weather in August and September is generally warm and this helps the bees to draw down the syrup and store it.

There are different types of feeder. I tend to use a bucket feeder but also use a box type feeder which has access to syrup at one end. These latter hold more syrup and are the best type for a strong colony because of their capacity.

It is good to get feeding done by the end of September while temperatures are reasonable. The bees need to reduce the water content of the mixture to the consistency of honey. Therefore the sooner they get the sugar syrup after the removal of the honey crop the better chance they have of making it ready for storing. I plan to give one feed to most of the colonies – this plus what honey they have and hopefully, a top up from ivy in late September and October should ensure they have adequate stores for the winter months.

I am now sorting through empty frames and deciding which ones to keep and which to destroy. It is a good question whether we should reuse old frames at all.  Is it worth it? Old, dark comb can harbour disease. Also as the cells are constantly cleaned and disinfected with propolis by young bees, the brood cells narrow giving rise smaller bees. Research shows that replacing over 50% of the brood frames annually reduces winter losses. In Denmark they persuaded all the beekeepers to replace 100% of frames each year and reduced the foul brood outbreaks completely.

It is probably best to melt the old combs and sell the wax for fresh foundation.  I have a solar wax extractor that works well, when and if, the sun appears in the apiary.

Tim Rowe the creator of the Rose Hive, is in no doubt about what we should do with old frames! He suggests that, ‘one of our most important jobs as beekeepers is to throw our old comb so the whole hive stays clean. We have to do this because when we moved bees into hives we interfered with the bees’ relationship with wax moths. Wax moths get very bad press which is a shame because they been an essential part of the honey bee story for millions of years; without them honey bees would have died out long ago because wax moths are one of the very few animals that can digest wax. In their real home – hollow trees – bees build new comb every year and then deliberately abandon old comb…along come the wax-moth caterpillars, like a team of demolishers and told the old, dirty, diseases comb away. The bees have a clean empty space to build in next year. ..In the hive, however there is simply is not the room for bees to do this. They are forced to use old combs riddles with bacteria and moulds – no wonder colonies get sick.  The answer is simple – act like a wax-moth and remove old comb, giving the bees room to build new clean comb. 

The question of reusing super frames doesn’t arise for me as I do cut comb which means I use fresh wax each year. If you are extracting,  honey gets left in frames so they end up getting heavier and less easy to extract. Again it is probably best to change these frames more frequently then we do especially frames that contain pollen.

Brood chambers and supers can be treated with 80% acetic acid glacial to kill off nosema spores – scrape off propolis and wax before treatment at the ascetic acid cannot penetrate them. You can buy acetic acid glacial from any of the chemical supply companies. I got some from MacEoin’s bee supplies in West Cork.

I am reflecting on the effectiveness of the various hive types that I use. I have National, Commercial, Langstroth both polystyrene and wood, and Rose Hives.

There is no doubt that the polystyrene hives build up faster in the Spring than their wooden counterparts. My experience is that they build up too quickly and swarm unless they are split.  The wooden hives on the other hand, seem to be more in tune with the weather and build up gradually and are ready for the flow. The best performing hive this year was the Rose hive – for those not familiar with this type of hive all the boxes are the same size and interchangeable. The fact that it was the best performing hive could have been due to many other factors including the quality of the bees!

Bee Blogs -August 2016

July is turning out to be a challenging month almost every year and not just for us humans but also for bees.  The first two weeks in July seem to be consistently wet and dull. In the 1980’s we ran a Summer Camp in the first two week in July and it always seemed to be wet. And the first two weeks in July are the most important weeks in the year for honey production – clover and bramble are in full flower yielding up their nectar. Early in the month I even got a warning from a beekeeping friend of mine to check my colonies in case they were starving!  I am told Global Warming means we will get even wetter summers. I am expecting a very modest crop of honey this year.
As we move into August, I am preparing the colonies for winter and ultimately for the year ahead. August and September are the key months to ensure bees survive the winter and are ready for the New Year. The bees born at this time of the year have a lot to do – they rear the winter bees so it is vital that are in good condition – sick or hungry bees trying to rear winter bees will mean poor colonies next year. Pollen is vital to build up the fat reserves of the winter bees. Lack of pollen at this time and the presence of disease would mean that the 2017 season is already in jeopardy. The two main tasks are to treat for disease and to make sure they have enough stores of the winter. I do this a bit earlier than most as September tends to be a busy time here.
I will use Apiguard to treat for Varroa. It is vital to follow the instructions.
You need to give two applications per colony at a two week interval.
Peel back the lid of the Apiguard tray leaving one corner of the lid attached to the tray.
Open hive and place on top of the brood frames- needs 0.5cm space above it by using an eke or empty super.
Close hive and replace after two weeks.
Most effective if used in late summer after honey is removed and the amount of brood is diminishing.  Needs temperatures of fifteen degrees centigrade.
I notice the ling heather is just coming into flower. If you have the energy and enthusiasm to move bees to the bog and the weather is good from mid-August into September you can be richly rewarded. Heather honey is dark, vicious and delicious. The bees don’t like working it much and can be very irritable. Only the strongest colonies should be taken to the heather. While there, they have to produce the all important winter bees so the queen needs to keep laying.
HEAD BUTTING
Apparently researchers have found that bees produce different vibrational ‘stop signals’ when attacked by predators while out foraging. These signals have different effects depending on the type of danger. A bee delivers a stop signal by giving another bee a brief, vibrational pulse or a ‘head butt’.
If they are attacked at a food source, bees will return to the hive and give stop signals to nest mates who may be recruiting others for the dangerous food source. These signals were known to inhibit recruitment by the waggle dance but up till now researchers did not know what triggered these ‘stop signals’.
HONEY DEW
This is produced by plant sucking insects such as aphids. It is a sugar rich liquid secreted mainly by aphids (green fly) as they feed on plant sap.
They penetrate the plant tissue (phloem) with their mouthparts and the sugary, high-pressure liquids is forced out of the gut’s terminal opening! Bees and wasps will collect. Trees such a beech,oak, pine, poplar and larch produce honeydew.
THREE ‘F’s
1. Forage – essential to have pollen source available all year round – a colony needs up to 200 pounds per year or approximately 10-12mg per bee. Winter flowering heather is a very useful plant.
2. Feed – whenever needed – as thick as possible 2 kilos to 1 litre or 3 kilos to 2 litres. In winter use fondant.  Put fondant over cluster in Feb – leave in plastic container or cover with cling film. Can cut 2.5 kilo bag into smaller pieces. Can spray with warm water to melt. Warm moisture from cluster will also help to soften. When you remove honey – feed and they will store in brood area and have it close to them in winter.
3. Frames only use premium wax. Economy wax is a mixture of waxes. Some advise that you glue frames together as tacks can corrode and frames can come apart. Evostick weather proof glue.

RESEARCH

I was passed on the results of research in UL which shows that honey bee colony losses in Ireland were the highest in 29 countries. The loss rates vary considerably between countries. In their survey the highest losses were recorded in Ireland and Northern Ireland followed by Wales and Spain. Problems with queens contributed heavily to the losses.
Dr. Mary Coffey of the National Apiculture Programme says: ‘the highest losses (over 30%) were in some parts of Counties Cork, Kerry and Kilkenny’.
