Roy Nettlebeck, I want to THANK YOU for your comments about research! I have always failed to understand why the average beekeeper will heed the advice of some local farmer, mechanic, plumber, carpenter (ALL HONORABLE VOCATIONS) about beekeeping rather than listen to the advice of some dedicated researcher, who has perhaps studied hard in college for 7-8 years to gain a degree in Entomology and then be hired by a university or government BEE LABORATORY to full-time try to find the solutions to our beekeeping problems. Many beekeepers have said, "The bee scientists and bee researchers have NOT found the solution for XYZ..... or the control of varroa jacobsoni, so we have HAD to listen to our experienced fellow beekeepers." The scientists are so limited by "arms" of the government in that whatever solution they find must meet several widely divergent criteria, such as: 1) must kill the mite, 2) must NOT kill the bee or its brood, 3) must NOT be dangerous to humans, 4) must not be collective in the wax. Further, beekeepers DEMAND that this product be CHEAP in price. Since this year is my 70th consecutive year of beekeeping, I have seen many problems that are not even imagined today by new beekeepers. Where would we be today without the findings of Terramycin, Fumidil-B, para dichlorobenzene, Gard Star, CheckMite, Apistan, Bee-Go, Artificial swarm pheromones, plastic foundation, and many other findings, all found by scientists and researchers, but none found by those myriad number of local beekeepers who were not trained scientists. Scientists don't always HAVE to use chemicals. Dr. Diana Sammataro "discovered" the effective control of tracheal mites by plain grease patties, just plain sugar and Crisco. Our dedicated scientists and researchers are trying to find those things that positively WORK, regardless of whether the active material is a dangerous chemical like the organophosphate coumophos (CheckMite) or something simple like a vegetable oil (Crisco). Normally I keep silent regarding these difficult subjects which are not unlike discussing religion or taxes where one never finds a winner, but you said "so much" so well, I just had to reply. Again, THANK YOU! George Imirie Certified EAS Master Beekeeper Past President of Maryland State Beekeepers Author of George's Pink Pages @ www.beekeeper.org/george_imirie/index.html
