As synthetic pesticides contribute to the global decline of pollinators, biopesticides have gained attention as more sustainable pest management alternatives in agriculture. Despite their perceived safety, there is increasing evidence that bioinsecticides can harm honey bees, which are crucial pollinators many commercial crops and key ecotoxicological models.

Interactions between environmental stressors may contribute to ongoing pollinator declines, but have not been extensively studied. Here, we examined the interaction agricultural fungicide Pristine (active ingredients: 25.2% boscalid, 12.8% pyraclostrobin) and high temperatures on critical honeybee behaviours. We previously shown that consumption of field-realistic levels this shortens worker lifespan in field impairs associative learning performance a laboratory-based assay. hypothesized would also impair homing foraging behaviours field, an with hot weather exacerbate effect.

Abstract Neonicotinoids represent over a quarter of the global pesticide market. Research on their environmental impact has revealed adverse effect cognitive functions pollinators, in particular bees. Cognitive impairments, mostly by behavioural studies, are phenotypic expression an alteration underlying neural circuits, matter deserving greater attention. Here, we reviewed studies field‐relevant doses neonicotinoids neurophysiology and neurodevelopment In particular, focus olfactory system as much knowledge been gained different brain areas that participate odour processing. Recent have detrimental effects at multiple levels system, including modulation odorant‐induced activity sensory neurons, diminished responses antennal lobe (the first processing centre) abnormal development connectivity within mushroom bodies (central neuropils involved multisensory integration, learning memory storage, among others). Given importance perception for aspects bee biology, reported disruption circuit, which can occur even upon exposure to sublethal neonicotinoids, severe consequences both individual colony levels. Moreover, multimodal structure such indicate neonicotinoids' translates other domains. Assessing pesticides is crucial understanding how influence behaviour ecological contexts defining effective sustainable agricultural practices.
