Abstract The use of agrochemicals is increasingly recognized as interfering with pollination services due to its detrimental effects on pollinators. Compared the relatively well-studied chemical toxicity agrochemicals, little known how they influence various biophysical floral cues that are used by pollinating insects identify rewards. Here, we show widely horticultural and agricultural synthetic fertilizers affect bumblebee foraging behavior altering a complex set interlinked properties flower. We provide empirical model-based evidence recurrently alter magnitude dynamics electrical cues, similar responses can be observed neonicotinoid pesticide imidacloprid. interact in modifying electric fields such changes reduce foraging, reflecting perturbation sensory events experienced bees during flower visitation. This unveils previously unappreciated anthropogenic interference elicited within landscape likely relevant for wide range chemicals organisms rely naturally occurring fields.

Widespread contamination of ecosystems with pesticides threatens non-target organisms. However, the extent to which life-history traits affect pesticide exposure and resulting risk in different landscape contexts remains poorly understood. We address this for bees across an agricultural land-use gradient based on assays pollen nectar collected by Apis mellifera, Bombus terrestris Osmia bicornis, representing extensive, intermediate limited foraging traits. found that extensive foragers (A. mellifera) experienced highest risk-additive toxicity-weighted concentrations. only (B. terrestris) (O. bicornis) responded context-experiencing lower less land.

Bees are essential pollinators of many crops and wild plants, pesticide exposure is one the key environmental stressors affecting their health in anthropogenically modified landscapes. Until recently, almost all information on routes impacts came from honey bees, at least partially because they were only model species required for risk assessments (ERAs) insect pollinators. Recently, there has been a surge research activity focusing effects non- Apis including other social bees (bumble stingless bees) solitary bees. These taxa vary substantially another several important ecological traits, spatial temporal patterns, foraging nesting requirements, degree sociality. In this article, we review current evidence base about pathways consequences We find that insights into bee resulting across biological organizations, landscapes, mixtures, multiple still infancy.

Abstract Pollinators, particularly wild bees, are suffering declines across the globe, and pesticides thought to be drivers of these declines. Research into, regulation has focused on active ingredients, their impact bee health. In contrast, additional components in pesticide formulations have been overlooked as potential threats. By testing an acute oral dose fungicide product Amistar, equivalent doses each individual co-formulant, we were able measure toxicity formulation identify ingredient responsible. We found that a alcohol ethoxylates, caused range damage bumble Exposure ethoxylates 30% mortality sublethal effects. Alcohol treated bees consumed half much sucrose negative control over course experiment lost weight. had significant melanisation midguts, evidence gut damage. suggest this explains reduction appetite, weight loss mortality, with dying from energy depletion. Our results demonstrate impacts need considered during regulatory consideration, co-formulants can more toxic than ingredients.
