Dear all, The Apiculture Lab at Michigan State University is looking for Apistan (fluvalinate) resistant varroa mites. We are conducting research to understand the mechanisms of Apistan resistance. So far we have identified 4 mutations that might be associated with resistance but we need to survey more mites to see if this correlation holds for mite samples from other places. Our previous publications on this subject are at: http://cyberbee.msu.edu/huangpub/2002JAR.pdf http://cyberbee.msu.edu/huangpub/2003IBMB.pdf If your lab or apiary have mites that are known to be resistant to Apistan, or if you know beekeepers who are having trouble controlling mites using Apistan, we would appreciate receiving some mite samples (about 50 mites in 95% ethyl alcohol). We will pay for the postage.
