The sublethal effects of pesticide poisoning will have significant negative impacts on the foraging and learning bees bumblebees, so it has received widespread attention. However, little is known about physiological spinetoram glyphosate exposure bumblebees. We continuously exposed Bombus terrestris to (2.5 mg/L) or under controlled conditions for 10 days. superoxide dismutase, glutathione-S-transferase, carboxylesterase, prophenoloxidase, α-amylase protease activities, changes in gut microbes were measured understand physiology Sublethal significantly increased dismutase activity decreased bumblebees but had no effect carboxylesterase activities. In addition, prophenoloxidase. Interestingly, we observed that neither two pesticides a dominant bacteria, altered structure fungal community, reduced relative abundance Zygosaccharomyces associated with fat accumulation. These results suggest do not affect detoxification system may bumblebee health by inhibiting energy acquisition. Our provide information low concentrations terms microbes.

Honeybee is an essential pollinator to crops, evaluation the risk assessment of honeybee larvae exposure pesticides residue in bee bread and honey important strategy protect colony due mixture these two matrices main food for 3-day-old larvae. In this study, a continuous survey five pyrethroid insecticides between 2018 2020 from 17 major cultivation provinces which can be determined as Northeast, Northwest, Eastern, Central, Southwest, Southern China, there was at least one type II insecticide detected 54.7 % samples 43.4 honey. Then, we assayed acute toxicity based on detection results, LD50 value 0.2201 μg/larva (beta-cyhalothrin), 0.4507 (bifenthrin), 2.0840 (fenvalerate), 0.0530 (deltamethrin), 0.1640 (beta-cypermethrin), respectively. Finally, hazard quotient calculated larval oral ranged 0.046 × 10-3 2.128 10-3. Together, empirical findings provide further insight into accurate contamination colonies caused by chemical pesticides, used valuable guidance beekeeping industry pesticide regulation.
