Professor David Evans is a virologist studying the biology of single stranded positive sense RNA viruses, including poliovirus, hepatitis C virus and deformed wing virus of honeybees. He has a fascinating, practical beekeeping blog, https://www.theapiarist.org/
- The 'June gap' and brood breaks; does the queen stop laying, or are the larvae cannibalised? Probably both, and more. Plus some brief comments on hayfever and honey, and determining when OSR/canola honey is ready for extraction (it's earlier than you might think).
- There are differences in the chemical and physical properties of wax in queen cells and worker comb. This is attributed to a specific group of young worker bees; the queen cell builders. What lessons are there for beekeeping from the identification of these bees and differences in the wax?
- The weather has a profound influence on bees and beekeeping; some thoughts on coping with extreme heat, the ideal conditions for queen mating, and predicting the onset of swarming.
- Miticides kill Varroa. They also have detrimental side effects for the brood, workers, drones, and queen. Some of these side effects are more damaging than others, but many can be avoided (or at least mitigated) with proper colony management.
- The vagaries of the weather, compounded by unexpected events, are what make beekeeping so endlessly fascinating … and challenging. Don't get flustered. Just keep calm and carry on and things should be OK.
- Bees spend more of their short lives learning about the environment during orientation flights than they spend foraging. Why are these flights so important, when do they start, and are bees that have yet to take them really 'non-flying bees'?
- Some observations on the impact of low overnight temperatures on colony development and spring swarming, and the use of Taranov swarm control to partition the flying and 'non-flying' bees to prevent swarming.
- Queenright queen rearing using the 'Ben Harden system' is an ideal way to produce queens without the need for huge cell raising colonies, or compromising honey production. A 'little and often' approach helps mitigate adverse conditions, and mistakes made when learning. Try it!
- Bait hives, ley lines, exotic parasitic mites and formic acid treatments … a spring medley of good and bad beekeeping topics.
- Winter DIY projects to make my beekeeping this year a little easier. Things for frames, mini-nucs, supers, finding bees, vaporisers, and queens. Some are novel, some are improvements, and some are poor facsimiles. All kept me entertained, and may help you in the months ahead.
