>>I have followed Tom's work very closely. After raising queens from those wild hives, he concluded that their survival was NOT due to genetics. I am not stuck on superior genetics although each colony has its own, unique characteristics/traits. Just like with feral cats, feral bees are just that - on their own for one or more generations. To me, the most significant point is NOT how the feral bees survive in the wild but the fact that they DO survive in my neck of the woods. This is a starting point. I keep my bees in Langstroth hives with plastic frames. The colonies derived from feral mothers have survived with mites longer that the purchased stock from Georgia, Florida, or California. Their ability to overwinter better - did not lose one colony last winter and none so far this winter - is nice. [But I do use OA once in the winter.] Last season I got 120lb+ per colony bet. the spring flow (poor) and the fall flow (very nice). That's significant to me, too. One more thing I'd like to try - this year if I get to making the set- up - is to let the bees build their own comb in Langstroth equipment. The feral comb, with one exception, from the brood nest area has averaged 5,0 mm. That's about 0,1 mm less than my Pierco frames. I am not out to make converts out of sceptics. I merely report my observations so that anyone interested can try working with local bees themselves. Having an open mind is a delightful thing. >>Another idea (mine) is: the colonies are widely spaced and high in trees may be very important. The colony spacing in managed apiaries is closer but I am not sure it affects mite survival. [The typically larger managed colony size is probably a bigger factor in a mite number explosion.] The closer spacing will affect foraging opportunities. As with regard to colony height, I removed one colony at ground level in a decaying tree on the north coast of Long Island 2 years ago. The homeowner reported seeing this colony swarm the previous 3 years and was getting tired of the spectacle. I think good nest thermodynamics make winter survival better and doubt the height affects the mites. >>Anyway, there is no difference from a wild hive and a hive that sits in somebody's back yard for 5 years without being inspected. And if you think those hives are immune, I would disagree. Besides, we are talking about better beekeeping here. I never said they were 100% immune. I only said that they survive better than the stock I had previously purchased. My beekeeping has not changed except that I am rasing my own queens and better raised queens do not equate to better mite resistance (as far as I know). >>Plus, I think the whole feral bee thing is a "mystique". There is nothing mystique - perhaps one can find collecting them "romantic" - about feral bees. Nature ruthlessly culls any ill- adopted stock. When a homeowner calls me to remove a nuisance honey bee colony, I believe I get to see & collect colonies that make it well through the gauntlet of nature's rigors. >>As far as us not having to worry about African genes in those wild swarms, don't bet on that one! You are right. They will likely be introduced in my area. Not sure if they will survive the winters in my area though. I am hoping not. And Africanized traits are not consistent - some in Africa and South America claim their bees are rather gentle although this does not seem to be the case in Mexico from what I've read. I perform feral removals without a veil after smoking and verifying the disposition of a colony. I do bring a veil just in case I eventually come across a nasty/Africanized colony.
