Organophosphate (OPs) insecticides are still widely used in pest control. The hydrolysis of OPs or oxons of organophosphorothionates by organophosphate hydrolases (OP-hydrolases) represents a major detoxification pathway of OPs. In this study, the response of insect OP-hydrolase activity to the allelochemical quercetin and the insecticide...

Bactrocera dorsalis is a notorious polyphagous pest in China, and its management strategies largely depend on methyl eugenol (ME), which has been widely used as an attractant to monitor and eradicate B. dorsalis populations for seven decades. However, the non-responsiveness levels in field B. dorsalis populations to ME is unknown. In this...

Wheat is a major crop and plays a significant role in food security in China. Cereal aphids Rhopalosiphum padi L. and Sitobion avenae Fab. are widespread worldwide and considered as serious pests in the winter wheat belt of North China. Natural enemies are well known for their ability to control aphid species in a wide range of cropping...

Competition is a key structuring component of biological communities, which is affected by both biotic and abiotic environmental stressors. Among the latter, anthropic stressors and particularly pesticides are noteworthy due to their intrinsic toxicity and large use in agroecosystems. However this issue has been scarcely documented so far. In...
