In the DeJong study that Jennifer Berry refers to, the drone comb, prior to the study, had drone brood in it....i.e. it was 'used' comb. Ms Berry goes to great pains to point out that there was surely residual pheromones in that comb.The studies quoted by Jennifer Berry at HAS back in about 2004
From our local beek meeting tonight the presentation said if you open the drone brood and find none that is a good indicator you have little to no varroa.Thanks..it is really quite amazing.
If you open drone brood and find no varroa is that a good indicator of levels in a hive?
Huh...neat. I think I'll open a few drone brood at my next inspection this Thursday and see if I find any. I have SBB but no sticky boards in so this might be informative.From our local beek meeting tonight the presentation said if you open the drone brood and find none that is a good indicator you have little to no varroa.
I bought an IPM board to stick in my Freeman traps for mite counts ... needed cutting down but worked great. But today the same supplier said they don't sell IPM boards separately and suggested I buy a plastic corrugated sign board from Home Depot and make my own. At $7+ each I'm interested in a better source. Plus, I'm not sure my girls can't read and I don't want them to see "FOR SALE" staring up at them from the bottom board.
You guys know of any inexpensive sources of that corrugated plastic board used for IPM boards? Sounds like lilhouse could use one.
Rarely does a day pass recently when I'm not glad I'm not a drone.
