Toxicity Of Formulated Insecticide Mixtures To Apis And Non-Apis Bees, Joseph Edward Belsky

Graduate Theses and Dissertations

This work investigates ecotoxicology of new insecticide mixtures to Apis and non-Apis bees. Previous studies have demonstrated the acute and sub-lethal toxicity of individual active ingredient insecticides to honey bees and to a lesser extent non-Apis bees. However, the contact toxicity of formulated premix insecticides containing multiple active ingredients to bees has not been thoroughly assessed. To address this void, laboratory studies simulating exposure to four premix insecticides under different field-realistic scenarios were conducted for two bee species.

Honey bee, Apis mellifera (Linnaeus) contact exposure was examined by simulating three scenarios: (1) when bees continuously forage in a field and …
