Short communication: Is there a difference in the sensitivity of Africanised and European honeybees to thiamethoxam...

The similarity of sensitivity of adult Africanised and European honeybees following acute oral exposure to thiamethoxam has been questioned. Data collated from adult acute contact and oral toxicity testing of a range of thiamethoxam containing products (solo and mixtures) shows that the toxicity of these products to Africanised honeybees can be directly predicted from the toxicity of the active substances to European honeybees. Similarly, the acute contact and oral toxicity of dimethoate to Africanised bees lies within the same range as European honeybees. There are no major differences in the sensitivity of Africanised and European honeybee individuals to thiamethoxam and dimethoate.
