TL;DR: It is suggested that pesticide mixtures in pollen be evaluated by adding their toxicities together, until complete data on interactions can be accumulated, and that chronic dietary exposure to a fungicide, pesticides mixtures, and a formulation solvent have the potential to impact honey bee populations.

TL;DR: The results demonstrate that pesticide exposure can substantially impact expression of genes involved in several core physiological pathways in honey bee workers, and there is substantial overlap in responses to pesticides and pollen-containing diets at the transcriptional level, and subsequent analyses demonstrated that pollen-based diets reduce workers' pesticide sensitivity.

TL;DR: Learning was impaired after ingestion of 20 µg organosilicone surfactant, indicating harmful effects on honey bees caused by agrochemicals previously believed to be innocuous, and may contribute to the ongoing global decline in honey bee health.

TL;DR: In vitro rearing of worker honey bees from larvae to adult emergence can be implemented as the standard protocol to determine the impact of pesticides on immature bees because of the protocol’s high control survivability, ease in end point determination, and high overall repeatability.

TL;DR: Two novel mutations, L925M and L925I, are identified in tau-fluvalinate resistant V. destructor collected at seven sites across Florida and Georgia in the Southeastern region of the USA using a multiplexed TaqMan® allelic discrimination assay, suggesting a high potential for resistance evolution if selection pressure is applied.
