The report of Larry Krengel P30LEK1@NIU struck me as interesting. Not the part about Varroa resistance, but the fact that menthol apparently was effective in knocking Varroa down to the bottom board. This is the first time I have heard about menthol acting on Varroa; it mostly has been used for tracheal mites and I believe still labelled only for that use. Another piece of the Varroa puzzle to remember is that even though mites are knocked off by chemicals, if they are not killed, they often can get right back on the insects. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Tom Sanford Extension Apiculturist University of Florida Mailing Address: Bldg 970, Hull Rd., Gainesville, FL 32611-0620 Voice phone 904/392-1801, Ext. 143 FAX 904/392-0190 INTERNET: [log in to unmask] BITNET: MTS@IFASGNV +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
