For some time now I have been interested in tracheal mite (and varroa) infestation, as most of us have. Like others, I have previously purchased putative resistant packages, and I have already ordered an number of new packages for the spring of so-called Tabor resistant bees, plus some Yugo bees that are reputed to be resistant. My question is simple: Where is the evidence of resistance? I would very much appreciate anyone's telling me about data that uphold the reputed claims to tracheal mite resistance. I assume that because I do not read all of the insect/parasite/ecological journals that I have missed the reports. I am unfortunately afflicted with a wealth of ignorance, so I would appreciate your tolerance with my having missed the reports. A number of companies now advertise resistant bees, and a number of us are eager to accept the claims of resistance. But as a scientist, I am naturally concerned about the data. Are these companies that advertise/sell so-called resistant bees obligated to backup their claims with scientific reports? Please don't get me wrong....with mites being the problem that they are, I am as eager (as a hobbyist/researcher) to grasp at straws as anyone else. However, as a scientist, I wonder about the extant evidence. Can anyone provide some reference to published data? Many thanks. ------------------------ John Batson --------------- ------------ Psychology--Furman Univ.
