We just received our copy of a Varroa mite management guide that was produced by the Honey Bee Health Coalition™ (HBHC). This is an extensive and excellent tool written primarily by Dr. Dewey Caron, and it that provides more details than in the one we had produced last year. In particular, they provide more extensive information on each of the chemical treatments available for Varroa control. I highly recommend that beekeepers use both guides when thinking about controlling this key parasite. We have provided downloadable PDF files of the HBHC guide and our IPM guide under our Resources heading.
A new and devastating pest of sorghum and milo requires extensive spraying of insecticides for control. The Yellow Sugar Cane Aphid was discovered on these crops in Mississippi last year. The aphid has shifted from sugar cane onto the new and vulnerable plant hosts (sorghum and milo). This pest can reach incredibly high populations in these fields in very short periods of time. The result is severe economic harm to the grower. As a consequence, many of these farmers are applying foliar insecticides 1-2 times per week. If you have bees near these fields, they are under much greater risk of exposure than in years past because of this greatly increase rate of insecticide application. I highly recommend that you move your bees away from these crops, or you find a way of protecting them from the potential of insecticide drift. The risk is much greater than in previous years near these fields of sorghum and milo.
