Abstract - The tau-fluvalinate content of 13 lot numbers of Apistan® strips was determined by high performance liquid chromatography (HPLC). The average percent tau-fluvalinate in strips from each lot number ranged from 9.95 to 10.64 %, which falls within the range specified in the Confidential Statement of Formula (CSF) on file with the Environmental Protection Agency. It is not likely that the reduced efficacy in parasitic mite (Varroa jacobsoni) control reported in certain areas of the US is due to the tau-fluvalinate content of Apistan® strips. © Inra/DIB/AGIB/Elsevier, Paris
