Chlorantraniliprole (CAP) is an insecticide with low toxicity and high efficiency, which is widely used in agriculture in China. However, its potential ecological risks remain unknown. In this study, we investigated the impact of different CAP concentrations on bacterial and fungal communities in soil based on high-throughput sequencing. The results showed that CAP application had no significant effect on soil bacterial and fungal diversity, but altered the bacterial and fungal community structure. In particular, the soil bacterial and fungal community structure in the low CAP concentration treatment group exhibited large variability. Compared with 0 day, the phylum level of bacteria changed at 115 days, and fungi changed at 175 days, indicating that soil microbial community might have significant correlation with CAP degradation in soil. Correlation analysis between soil properties and microbial communities showed that TN, TP, and NO-N were three key factors that significantly influenced microbial community structure. These results provide basic data for studying the effects of pesticides on ecosystem and potential remediation strategies of polluted soil.
氯虫苯甲酰胺（CAP）是一种低毒高效的杀虫剂，在中国农业中广泛使用。然而，其潜在的生态风险仍然未知。在本研究中，我们基于高通量测序研究了不同浓度的CAP对土壤细菌和真菌群落的影响。结果表明，施用CAP对土壤细菌和真菌多样性没有显著影响，但改变了细菌和真菌群落结构。特别是，低浓度CAP处理组的土壤细菌和真菌群落结构表现出较大的变异性。与第0天相比，细菌的门水平在第115天发生变化，真菌在第175天发生变化，表明土壤微生物群落可能与土壤中CAP的降解有显著相关性。土壤性质与微生物群落的相关性分析表明，TN、TP和NO-N是显著影响微生物群落结构的三个关键因素。这些结果为研究农药对生态系统的影响以及污染土壤的潜在修复策略提供了基础数据。
