Chlorpyrifos is a widely used organophosphorus insecticide. The acute oral
24 h median lethal dose (LD50) value of chlorpyrifos in Apis mellifera and in
Apis cerana was estimated to assess differential acute chlorpyrifos toxicity
in both bee species. The LD50 values of chlorpyrifos in A. mellifera and in
A. cerana are 103.4 ng/bee and 81.8 ng/bee, respectively, which suggests
that A. cerana bees are slightly more sensitive than A. mellifera bees to
the toxicity of chlorpyrifos. Doses half the acute LD50 of chlorpyrifos were
selected to study behavioral changes in both bee species using proboscis
extension response assay. A. mellifera foragers treated with chlorpyrifos
showed significantly lower response to the 10% sucrose solution compared
to control bees after 2, 24 and 48 h. Chlorpyrifos significantly impaired
the olfactory learning abilities and 2 h memory retention of forager bees
regardless of honey bee species, which may affect the foraging success of
bees exposed to chlorpyrifos.
