Report: No Organic Bee Losses
"Sharon Labchuk is a longtime environmental activist and part-time organic beekeeper from Prince Edward Island. She has twice run for a seat in Ottawa's House of Commons, making strong showings around 5% for Canada's fledgling Green Party. She is also leader of the provincial wing of her party. In a widely circulated email, she wrote:
I'm on an organic beekeeping list of about 1,000 people, mostly Americans, and no one in the organic beekeeping world, including commercial beekeepers, is reporting colony collapse on this list. The problem with the big commercial guys is that they put pesticides in their hives to fumigate for varroa mites, and they feed antibiotics to the bees. They also haul the hives by truck all over the place to make more money with pollination services, which stresses the colonies.
Her email recommends a visit to the Bush Bees Web site at Here, Michael Bush felt compelled to put a message to the beekeeping world right on the top page:
Most of us beekeepers are fighting with the Varroa mites. I'm happy to say my biggest problems are things like trying to get nucs through the winter and coming up with hives that won't hurt my back from lifting or better ways to feed the bees. This change from fighting the mites is mostly because I've gone to natural sized cells. In case you weren't aware, and I wasn't for a long time, the foundation in common usage results in much larger bees than what you would find in a natural hive. I've measured sections of natural worker brood comb that are 4.6mm in diameter. This 4.6mm comb was drawn by a hive of commercial Carniolans and this 4.7mm comb was drawn on the first try by a package of commercial Carniolans. What most people use for worker brood is foundation that is 5.4mm in diameter. If you translate that into three dimensions, instead of one, that produces a bee that is about half again as large as is natural. By letting the bees build natural sized cells, I have virtually eliminated my Varroa and Tracheal mite problems. One cause of this is shorter capping times by one day and shorter post capping times by one day. This means less Varroa get into the cells and less Varroa reproduce in the cells. I have mostly done this either with wax coated PermaComb (fully drawn plastic comb) or self drawn comb on foundationless frames or frames with blank starter strips. 4.9mm foundation is available from Dadant and Sons and from Brushy Mt. This size(4.9mm) has been found sufficient to resolve the mite problems. For more information on small cell: Bush Farms
