Influence of the neonicotinoid insecticide thiamethoxam on soil bacterial community composition and metabolic function

Changcai Wu et al.

Summary: This study investigated the effects of the neonicotinoid insecticide thiamethoxam on bacterial communities and metabolic functions in two types of soils. Thiamethoxam treatment significantly affected soil bacterial abundance, reduced microbial diversity, and temporarily altered the bacterial community structure. The study also identified changes in the populations of certain beneficial and pollutant-degrading bacteria, as well as the increased abundance of biodegradation and pesticide degradation genes, including cytochrome P450. The conclusions of this study will contribute to safety evaluations and degradation-related research on neonicotinoid insecticides in soil.
