I am a high school biology teacher and also a beekeeping hobbiest (3 hives, one is particularly bad shape).I teach a section of Advanced Biology to seniors and most of these students are planning to become biologists. After 8 months of pushing them through the rigors of modern biochem and genetics and embryology (etc) I like to let them loose on current research being done in areas that I am interested in. Naturally, that's bees. We are currently looking at 2 problems: 1) What frequencies of sound can bees detect? 2) Population genetics and evolution of bees with particular interest in changes in the enzyme malate dehydrogenase (MDH)in bee populations throughout the world. Last year we made some progress on the sound problem but ran into some technical difficulties which led us to doubt our results. We are very interested in hearing from anyone who can point us to methods of operant conditioning in bees: our main problems were in the areas of holding them down during training, possible stimulus-response methods and sound delivery systems. If anyone can offer help, we would really appreciate it. My e-mail address is [log in to unmask] Thanks, Reid Walker
