摘　　要：本试验研究了施用除草剂对烟田节肢动物群落的影响。结果表明 ,施药区植食类相对丰盛度明显增加 ,尤其是蚜科 ,捕食类相对丰盛度明显减少 ,特别是蜘蛛类的皿蛛科 ;节肢动物群落和植食类亚群落的多样性指数和均匀度降低 。The effects of herbicide application on the arthropod comunities were studied in tobacco fields. The results indicated that in the fields with herbicide use,the relative abundance of phytophages became higher obviously,especially Aphididae,and that of predators became lower, especially Linyphyiidae.The diversity indexes and evenesses of arthropod commnities and phytophage sub communities reduced,and that of predator and spide sub communities increased.
