TLDR
It is submitted that 2 key processes underlie honey bee pesticide exposure: 1) the acquisition of pesticide by foraging bees, and 2) the in‐hive distribution of pesticide returned by foragers.Abstract:
The role of pesticides in recent honey bee losses is controversial, partly because field studies often fail to detect effects predicted by laboratory studies. This dissonance highlights a critical gap in the field of honey bee toxicology: there exists little mechanistic understanding of the patterns and processes of exposure that link honey bees to pesticides in their environment. The authors submit that 2 key processes underlie honey bee pesticide exposure: 1) the acquisition of pesticide by foraging bees, and 2) the in-hive distribution of pesticide returned by foragers. The acquisition of pesticide by foraging bees must be understood as the spatiotemporal intersection between environmental contamination and honey bee foraging activity. This implies that exposure is distributional, not discrete, and that a subset of foragers may acquire harmful doses of pesticide while the mean colony exposure would appear safe. The in-hive distribution of pesticide is a complex process driven principally by food transfer interactions between colony members, and this process differs importantly between pollen and nectar. High priority should be placed on applying the extensive literature on honey bee biology to the development of more rigorously mechanistic models of honey bee pesticide exposure. In combination with mechanistic effects modeling, mechanistic exposure modeling has the potential to integrate the field of honey bee toxicology, advancing both risk assessment and basic research.

Pesticide residues in honey bees, pollen and beeswax: Assessing beehive exposure
TL;DR: In this article, a total of 133 samples were screened for 63 pesticides or their degradation products to estimate the pesticide exposure to honey bee health through the calculation of the hazard quotient (HQ).
Pesticide residues in honey bees, pollen and beeswax
TL;DR: Beeswax revealed high levels of miticides used in beekeeping such as coumaphos, chlorfenvinphos, fluvalinate and acrinathrin, which were detected in more than 75% of samples, and pollen samples contained the largest number of pesticide residues and relevant hazard (HQ > 50) to bees.

TL;DR: A socioecological framework designed to synthesize the pesticide-pollinator system and inform future scholarship and action is presented, consisting of three interlocking domains-pesticide use, pesticide exposure, and pesticide effects-each consisting of causally linked patterns, processes, and states.

Characterizing honey bee exposure and effects from pesticides for chemical prioritization and life cycle assessment.
TL;DR: A method for quantifying pesticide field exposure and ecotoxicity effects of honey bees as most economically important pollinator species worldwide is developed, and should be expanded to cover all relevant pesticide-crop combinations.

Influence of land use on chlorpyrifos and persistent organic pollutant levels in honey bees, bee bread and honey: Beehive exposure assessment
TL;DR: Results revealed that the land uses and seasonal variations have directly impacted on the levels of agrochemicals, PCBs and PBDEs found in the beehive matrixes, highlighting the importance of soils as sink of these persistent contaminants, which became available depending on environmental conditions.
