As several people were picking up their Bees and there was a lot to cover we went straight up to the apiary. This weeks course was all about Bee diseases and being able to identify them. As a lot of Bee diseases are first noticeable in the brood as a Beekeeper you need to be able to remove Bees from a frame so you can see into the cells. We split into 3 groups and was shown how to shake the Bees off a comb. Once Ivor had done a frame the hive tool was passed round so everyone had a turn. When it came to my turn I gently removed a frame and had a quick look for the Queen. While I was looking for her I noticed a Queen cup with a white residue on it; I asked Ivor what it was and while he was looking at it a large caterpillar fell of onto the hive below, Ivor quickly caught it and disposed of it. It turned out to be a greater wax moth larva! It was now time to shake the Bees; to do this you hold the frame at either side and then shake with a couple of quick sharp thrusts downwards, which should dislodge enough Bees to be able to see the brood underneath. This should be done to all brood frames at least a couple of times a year if you want to catch diseases before they become a problem. After everybody had shaken a frame we moved straight onto putting the nucleus hives into everyone's hives and then left them to collect at the end.
After a quick break we went straight onto the classroom session which this week was about Bee disease and pests. We were shown several slides with various different problems present. Things we were told to look out for were:-
- Uneven brood colour; a frame of capped brood should all have a very similar colour, newer comb will be lighter than old comb.
- Smells; strong or sour odours can be signs of foulbrood
- Uneven brood pattern; a failing Queen can cause cells to be regularly missed
- Larva in cells looking different; they should be ivory white and curled in a "C" shape, if they are a different colour or seem twisted in the cell that could be foulbrood
- Capped cells look sunken; capped brood should be lightly raised, again could be foulbrood
I also bought a new suit for my better half so she can get a little more involved. She has decided that Bees aren't as bad as she thought but still prefers her chickens, which she blogs about here.
