This is the time of year when we are attempting to minimise the number of varroa in our colonies so as to give the bees a better chance over the winter. It was because of this that I have been reading the Varroa booklet from the NBU.
The booklet is important but quite hard work. So after ploughing through that I went to a video by Dr Samuel Ramsey which he gave to the Institute of Northern Ireland Beekeepers at their Honey Show. I suspect I learned more from that video about Varroa than I did from all my reading.
For example – look at the bee above. When you open the hive if you see that you know you have a varroa problem. If you do not see that then do you have a varroa problem? Well the answer is in the video. It turns out that varroa prefer to hide under the bee where they can get better access to the Fat Bodies. It truly is a fascinating video.
Not only is the video highly informative but it is also highly entertaining. He is an excellent speaker and I recommend you watch the video so that you better understand the reason that varroa is such a problem. If you are also inspired to read his research papers on varroa as well as on other subjects then he has a website which is worth exploring.
