Now this is coming from the biologist in me: so if we want colonies that are more resistant to these pests, it seems we should let natural selection (nature) take its logical course and allow our colonies to raise their own queens. Sounds like I should not be buying anymore queens. Just take my best colony, take out a frame, nuc it and allow the workers to make a queen from that??? Now I know that is what most breeders do, but it would be more fun for me to do it myself and save some dough! The speed with which this queen and small colony drew out two frames and brood and made stores during a dearth is quite amazing to me. So I'm thinking I want more of the same. Ya'll thought this was some bogus thread--two pages already!!!
