Abstract Since the EU banned classic neonicotinoids like imidacloprid and clothianidin, they may be replaced by more recently marketed insecticides such as flupyradifurone. However, all operate on same neuropharmacological principle selective agonists at insect’s nicotinic acetylcholine receptors. Here we investigated impact of flupyradifurone, clothianidin neuronal processing in auditory pathway desert locust Schistocerca gregaria . While stepwise increasing insecticide concentration haemolymph, extracellularly recorded spike responses afferents tympanal nerve interneurons neck connectives. All three showed a very similar dose-dependent suppression ascending towards brain, whereas sensory neurons ears appeared unaffected. Furthermore, systematic injection experiments demonstrate that dosages which already supress information transfer are far too low to induce typical poisoning symptoms trembling, spasms, paralysis. We discuss how sublethal intoxication with classical or functionally related flupyradifurone disrupt postsynaptic balance between excitation inhibition locusts other orthopteran insects.

Monitoring the environment for pollution, pesticides, and pathogens is crucial protecting human, agriculture, overall ecosystem health. Diverse strategies ranging from physical sensors to sentinel species have been used environmental monitoring.

During foraging, bees are exposed contaminants carry them their hives where they be detected quantified.

Insect nicotinic acetylcholine receptors (nAChRs) are pentameric ligand-gated ion channels mainly expressed in the central nervous system of insects. They directed targets many insecticides, including neonicotinoids, which most widely used insecticides world. However, development resistance pests and negative impacts on bee pollinators affect application have created a demand for alternatives. Thus, it is very important to understand mode action these not fully understood at molecular level.

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.

Honeybees and wild bees are among the most important pollinators of both cultivated landscapes. In recent years, however, a significant decline in these has been recorded. This decrease can have many causes including heavy use biocidal plant protection products agriculture. The frequent residues bee originate from fungicides, while neonicotinoids and, to lesser extent, pyrethroids popular insecticides detected products. There is abundant evidence toxic side effects on honeybees produced by neonicotinoids, but only few studies investigated because they generally regarded as not being harmful for bees. field, variety substances taken up mixtures their combinations be lethal pollinators, depending specific group insecticide or fungicide. review discusses different major fungicide classes Fungicides inhibiting sterol biosynthesis pathway strongly increase toxicity pyrethroids.
