Current PRTF Projects Compilation and statistical analysis of pollen and nectar pesticide residue concentrations Completed PRTF Projects Evaluation and improvement of models used to predict over-wintering sucess of honey bee colonies Re-evaluation of the Brigg’s plant uptake model Evaluation of the relative toxicity of active ingredients versus formulation products Improving the honey bee larval toxicity test Chronic larval and adult honey bee laboratory testing: Which dietary additive should be considered when a test substance is not solubilized in acetone? Comparison of knowledge contributed to the risk assessment by two different larval tests Improvements in the foliage residue toxicity test
