Pesticide Toxicity to Bees 

UCR research and extension on pesticide toxicity to honey bees.


Much of this information was developed by E. Laurence (Larry) Atkins at UCR: Reducing Pesticide Hazards to Honey Bees an Adobe Acrobat Reader (.pdf) formatted version of University of California extension Leaflet 2883.

Bee Toxicity Calculator a spreadsheet (for Microsoft Excel) that can calculate expected bee kill given the field application dosage, the LD50 of the pesticide to honey bees, and the slope of the probit regression. Data on these parameters is included in another sheet (from Leaflet 2883).

The honey bee laboratory at UCR is directed by P. Kirk Visscher.
