摘　　要：为了解四川南充地区花生田昆虫群落结构,明确群落多样性水平及昆虫发生动态变化,利用马来氏网共收集到分属于15目、144科共25 393头昆虫样本。其中,膜翅目和鞘翅目占总数的20%以上;半翅目和双翅目占总数10%以上;其余各目均低于10%。试验区昆虫群落多样性指数、丰富度和均匀度相对比较平稳,其中,多样性指数在2.028~2.941之间;丰富度在55~96之间;均匀度指数在0.497~0.705之间。优势集中指数和丰盛度波动幅度较大,优势集中指数在0.066~0.280之间,丰盛度在1 123~4 558之间。综上,四川南充地区花生田昆虫群落具有丰富的多样性。In order to discover the insect community structure in peanut field of Nanchong, Sichuan, the level of community diversity and the dynamic changes of insects were determined. A total of 25,393 insect samples belonging to 15 orders and 144 families were collected by Malaise trap. Among them, Hymenoptera and Coleoptera accounted for more than 20% of the total;Hemiptera and Diptera accounted for more than 10% of the total;the rest orders were less than 10%. The diversity index, richness and evenness of insect community in the experimental area were relatively stable, among which the diversity index ranged from 2.028 to 2.941. The richness was from 55 to 96;the uniformity index was from 0.497 to 0.705. The index of dominance concentration and the degree of abundance fluctuated greatly. The Simpson ranged from 0.066 to 0.280, and the relative abundance ranged from 1,123 to 4,558. In conclusion, the genetic diversity of insect community is rich in peanut field of Nanchong, Sichuan.
