Abstract - Three experiments were conducted on queen and worker honey bees (Apis mellifera L) to assess effects of treatment with fluvalinate impregnated (Apistan®) strips. A 5-d treatment of worker bees (weighing 1.4 kg per group) in screen packages with a fluvalinate strip (2.5% a i, 2.5 x 13 cm) did not increase mortality. Overwintered laying queens (n = 30), and newly mated queens (n = 60) were treated in Benton mailing cages for 5 d with fluvalinate (Apistan Queen Tabs, 1% a i, 2.5 x 1.3 cm). All queen mortality occurred on d 4 and 5 of the treatment period, which is beyond the recommended 3-d-treatment. Neither group of treated queens exhibited a significant increase in mortality. However, attendant worker bees in the second trial exhibited a significant increase in mortality during treatment. No differences were observed in colony acceptance of queens, brood viability, or supersedure rates at 2 and 6 months post-exposure.
