Recovery of learning responses by honeybees following a sublethal exposure to permethrin


USDA-ARS, 2000E. Allen Road, Tucson, Arizona 85719, U.S.A


ABSTRACT A classical conditioned response was used to evaluate the learning behaviour of honeybees (Apis mellifera L.) which survived a sublethal dose of permethrin. Treated bees had lower learning response levels than untreated bees for 3 days, but regained normal learning ability on the fourth day after exposure. However, bees trained prior to exposure showed no significant effect of permethrin on their conditioned response.
