Report of March 2018 winter meeting

Report of the March meeting.

What’s on the Mind of Pollen Gatherers? A talk by Dr. Natalie Hempel de Ibarra from the University of Exeter.

Natalie and colleagues have been researching the abilities and behaviours of bees when pollen gathering. Relevant questions they are trying to answer are:

  • Do bees foraging for pollen have preferences for certain types of pollen?
  • Do they know what they need to collect?
  • Can they discriminate between pollen from different plants in favour of their nutritional requirements?

The plant’s point of view:

For the vast majority of flowering plants the goal is cross pollination, which will maintain or improve the gene pool and improve the species’ chances of survival. Many animals will pollinate by transfering pollen from flower to flower but pollen removal for feeding comes at a cost, both in terms of energy and lost reproductive potential.

In evolutionary terms pollen has been an insect food source for 100-120 million years. Nectaries appeared about 70 million years ago to attract pollinating insects and cut down on the energy-expensive production of pollen. This strategy was hugely successful as part of the expansion in new species around that time.

The bee’s point of view:

Crocus pollen

Bees are 100% dependent on flowers for their nutritional requirements, nectar and pollen.

When feeding, insects should:

  • Make the lowest effort for the highest benefit and
  • Reduce their exposure to toxins

Enormous variation in pollen nutritional quality exists within species and between populations, so how selective should bees be? The benefits of generalised foraging behaviour are:

  • Wider diversity of nutrients
  • More flexibility to collect sufficient pollen
  • Adaptability to change
  • Dilution of toxin intake

So, can bees distinguish pollen varieties by taste? The answer is ‘Probably yes’, although they have only 10 taste receptors (we have 5, bumble bees have 23). The bee brain is equipped for learning smell and taste so knowledge and experience of pollen taste could well be a driving force for efficient pollen collection, although the primary driver appears to be quantity of pollen collected. This may partially answer the first question of preferences for certain types of pollen.

To answer the second question, experiments in the past have focussed on whether foraging bees can determine the quality of pollen from different plant species, but without a great deal of success. More recent experiments have adopted a novel experimental approach testing the learning ability of bees with pollen rewards.

Bees possess receptors on their antennae, so individual bees in cages can be trained to extend their proboscis for a reward at the same time as the antennae are exposed to an odour (see image below). This conditioning failed to elicit a response with a variety of dry pollen samples. However experiments conducted with bumblebees and wet samples of varying concentration showed the bees’ ability to distinguish between pollen and pollen-surrogate differing in protein content. Bees preferred a particular pollen type, but this was not always the most concentrated sample. Only when presented with the biggest difference in concentration did the bees prefer the higher concentration.

Methods for experimental testing of pollen collection and pollen-rewarded learning in bees.

Probosis extension
Probosis extension

(a) When stimulated with pollen bees spontaneously respond with a proboscis extension (PER). The typical sucrose reward was substituted with pollen in an attempt to train honeybees to associate an unfamiliar odour with pollen reward.

Pollen in Petri dish
Pollen in Petri dish

(b) Bees accept pollen presented in Petri dishes, which can be presented on various coloured rings to test learned responses.

In conclusion it seems bees will use all the cues available to form their experience of pollen collection. These cues include taste, colour, ease of collection, abundance and possibly freedom from toxins.

  • Do they have a preference for certain types of pollen? Yes
  • Do they know what they need? No good evidence that they do, or indeed that they would have to.
  • Can they discriminate nutritionally? To some extent, perhaps, but it is more important to collect large quantities and avoid toxins.

Report of the February 2018 winter meeting

Time Saving Inventions for the Practical Beekeeper, a talk by Will Steynor.
Report of the February winter meeting 2018.

Last year Will Steynor told us how he successfully combined running 70 colonies, a profitable beekeeping business and his job as a full time commercial airline pilot. He came back this year to show us some of the inventions and adaptations that made it possible.

Hives

Will uses the Smith design made from weather resistant plywood. His hives are of simple construction, using only four pieces of timber screwed together, with a rebate cut into the end wall to take the shortened lugs of the National frame. By using slightly thinner plywood on the side walls it is possible to fit 12 frames as opposed to the normal 11, which goes some way towards offsetting the lack of brood space in a standard Smith hive.

Smith hive

As can be seen in the photo all the hive parts are held together with toggle clips, and with the addition of simple wooden handles this makes the hives easily transportable for migratory beekeeping without the need for additional strapping.

Mesh floors are made with an 8mm rim and a pivoted entrance. A small clip (just visible on the right of the alighting board) allows the entrance to be securely closed for transport or held open in the apiary with no danger of accidental closure. These built-in features avoid the need for entrance blocks or mouse guards.

Out Apiaries

The only pieces of kit that Will takes to and from his out apiaries are supers and sugar syrup. Everything else that might be needed is kept with each hive. This includes a rapid feeder which is left on all year round, a queen excluder and a crown board (no holes).

The feeder is based on a standard design with a few additions and modifications. Bees come up through the slot and feed on the syrup in the normal way. A small hole near the base allows bees into the main part of the feeder to clean up, which avoids mould growth.

By changing the cover to include a couple of Porter escapes the feeder then acts as a clearer. A small quantity of syrup seems to attract bees from the supers above and clearing only takes about 3 hrs instead of the normal 24 hrs.Feeder/clearer diagram

Stands – simple and durable. Standard breeze blocks placed on the ground and levelled, with a large hollow block placed on each. 2” x 4” timber frames on top.
Roof – uses 9mm ply to make a deep (9”) roof. The advantages are that it does not blow off and there is sufficient space to accommodate the feeder and spare equipment at all times of year.

Solar wax extractor

His extractor is large enough to take several brood frames at once. Frames straight from the hive are left in the extractor for several days so that all the wax has drained and the wood work sterilised by the heat. By knocking each frame while still warm nearly all the cocoons can be dislodged leaving very little scraping to do. Cost? Nil!

Will also makes his own foundation from the recycled wax. When attaching to the frames he pours molten wax along the top edge instead of using a wedge. Saves time and fiddly nailing plus there are fewer places for wax moth larvae to hide.

Queen rearing

Half width super frames form the basis of a simple technique. 24 of these frames can be fitted into a modified super and placed on a strong colony for the queen to lay in. When eggs and larvae are present the frames can be distributed to small boxes where queen cells will be built. The new queens can then be introduced into existing colonies using hair curlers.

There were lots of other gadgets on display including a modified kitchen sink for uncapping supers, a bain marie for wax melting, made from two stainless steel bowls, a kettle element and a cooker thermostat, and a simple honey warming cabinet using lamps as heaters and a fan from a computer.

We hope this talk will stimulate ideas for making your beekeeping easier.

 

Report of the January 2018 winter meeting

Dead Bees don’t Buzz – Surviving the Winter
Report of talk by Roger Patterson at the joint meeting of West Dorset and East Devon Beekeepers, January 2018

Roger started off by reminding us that bees are wild animals with a yearly cycle of nest expansion in the spring and contraction in autumn, and although they are very adaptable it is often the case that beekeepers work against the natural cycles leading to loss of bees through beekeeping errors.

Beekeeping advice is very variable, possibly based on human perceptions, and there is therefore a need to consider the situation from the bees’ point of view. Simply put they try to maintain population stability and prepare for the future.

In the wild it is definitely a question of survival of the fittest. Weak or diseased colonies are less adaptable and will die out, so wild colonies tend to be strong, healthy and adapted to their environment.

Roger went on to show how a wild colony behaves through the yearly cycle, with the cluster moving up to fresh stores in winter then the queen starting to lay in the empty cells below the nest as the weather warms up.

Other characteristics of successful wild colonies that we should take note of are:

  • the bees tend to be dark
  • nests are well above ground level and are therefore less prone to damp
  • the entrance is defendable
  • usually well insulated in a tree or building
  • the interior is 100% propolised
  • they always have their food stores above or behind the brood
  • they tend to have the brood nest near the entrance

How can we copy them and improve our beekeeping and winter survival?

Allow the bees plenty of time at the end of the summer to arrange their stores where they want them. Consider putting frames “cold way” over winter to reduce the risk of isolation starvation.

Isolation starvation diagram
Isolation starvation in the winter months

With frames ‘warm way’ the cluster near the entrance (green area) will not move to stores at the back of the hive (red) during cold weather.

Make sure there is adequate air circulation round the hive to reduce dampness.

Ensure colonies going into winter are strong, healthy and well populated with plenty of young bees. A small colony can be given surplus frames of brood to boost numbers.

Unite weak colonies, especially those colonies with poorly performing queens.

When feeding in the autumn feed little and often to allow the bees to keep up with pollen collection and storage in proportion to the quantity of syrup, otherwise they will not have sufficient protein to produce healthy brood during the winter months.

Conditions are something the beekeeper can do something about. Remember that cold doesn’t kill bees but damp conditions do. Roger advised to always leave the tray out of the mesh floor for this reason. The beekeeper can also ensure protection against pests such as wasps, mice and woodpeckers.

Monitoring during the winter months usually involves hefting the hives. A word of warning! This only works if the stores are still liquid. Any honey which has solidified, such as ivy, will be unavailable to the bees.

Photo of dead bees due to isolation starvation

The picture shows solidified stores next to the cluster preventing the bees from moving to liquid honey, just a few inches away, during cold weather. If in doubt feeding a small quantity of fondant will let you know whether the bees are ok or need help.

Finally, remember that Varroa has not gone away. You need to monitor throughout the year and do something about high counts BEFORE it gets out of control.

 

 

Report of East Devon AGM, 2017

Report of East Devon Beekeepers AGM, 2017

The reports discussed at the AGM show the branch has a full programme of activities and financially has managed to break even over the past year. The Chairman thanked the Committee for their hard work organising these activities for the benefit of members.

The Beginners Course was well attended in the classroom sessions and continued to attract good attendance at the practical apiary sessions.
The teaching apiary is now back up to strength after a poor start thanks to the work of David Shale, Andy Legg and helpers. The strimming team were also thanked for their efforts to keep the grass under control.

This year 5 candidates prepared for the Basic Assessment and took the exam with 5 passes, 2 with credit.
The Craythorne cup for the Basic candidate with the highest marks in East Devon went to Nick Silver. Congratulations to all of them.

Voting took place for Committee members. Chairman – John Badley, Secretary and Membership – Val Bone, Treasurer – Keith Bone, Committee – Andy Legg, Sue Babey, Mary Boulton, Alasdair Bruce, Ralph Cox, Rosemary Maggs, Colin Osborne and Richard Simpson.

After refreshments, Ruth and Ian Homer gave a fascinating talk on the 8th International Meeting of Young Beekeepers event, largely organised by them, that was held at Marlborough College in July of this year.

Planning was well under way 1½ years before the event and, as Ian and Ruth explained, there were many hurdles to overcome. In the end IMYB 2017 was attended by 19 teams speaking 13 different languages!
All the participants were divided up into small international teams, each team identified by their own coloured baseball cap. The tasks included activities such as frame making, grafting larvae, inspection and handling bees to show the competitors basic skills. Other tasks required problem solving with discussion and team working.

The assessments took place in the mornings. On the first afternoon the competitors were treated to a tour of Stonehenge and on the second afternoon they all departed for a DCA hunt on nearby Marlborough Downs. This proved to be the highlight of the event for some of the competitors as they had never witnessed the phenomenon before.

The accompanying adults were treated to tours of Stonehenge, Bath and Salisbury.
In conclusion, the weather was perfect, the bees behaved perfectly and the competitors and accompanying adults voted IMYB 2017 as the best yet.

It is now up to us to encourage more young beekeepers into the craft.

Scientists sew trackers to Asian Hornets to find and destroy nests before they kill honeybees
Britain’s beekeepers are turning to technology to prevent aggressive Asian hornets destroying their colonies. In a first successful trial, experts at the University of Exeter attached tracking devices to the backs of the voracious hornets and then followed them back to their nests.
Asian hornet information
The June edition of the BBKA News has extensive information about the Asian hornet threat. In particular, pages 209 and 210 have full colour reproductions of the Asian hornet alert document issued by the Non Native Species Secretariat (NNSS) for you to cut out and use as your personal guide to identification of this invasive species.
