摘　　要：【目的】研究阿克苏地区中部夏季农田蛾类昆虫群落多样性。【方法】应用智能测报灯诱集农田蛾类昆虫,采用多样性测度方法。【结果】采集灯下蛾类昆虫标本10 338头,分属于鳞翅目夜蛾科、螟蛾科、天蛾科、尺蛾科等11科;农田蛾类昆虫多样性指数(H')和均匀性指数(J')随时间变化趋势一致,7月中旬和8月中旬最高;优势集中性指数(C)6月中旬最高;群落丰富度指数(E)6月初最高,随后下降,起伏不大。【结论】阿克苏地区中部夏季农田灯下蛾类昆虫120种,种—多度关系模型表明阿克苏地区中部农田生境较好;不同科优势种个体数量差异较大,根据灯下蛾类昆虫生物多样性随时间动态变化,为农田虫害防治和指导生产实践提供科学依据。[ Objective ] The project aims to survey the biodiversity of moths in central Aksu area farmland indices were applied to measuring the biodiversity. [ Result] It was reported that 10,338 specimens were collected in central Aksu area farmland, including 11 families of Lepidoptera, such as Noctuidae, Pyralidae, Sphingidae, Geometridae and so on; Statistics analysis indicated that the trend of the changes with dates in the diversity index （H＇） is coincident with that of evenness index（J＇） , the index was highest in middle of July and August ; The dominance index （ C ） was higher in mid - June ; The richness index （ E ） was higher at the beginning of June, and then dropped to the low level. Itg changes were poised. [ Conclusion] There were 120 species of moths under the lamp found in central Aksu area farmland, and the abundance distribution model of moth species indicated that the habitat of farmland was fine; It was highly different between the numbers of different species in different families. According to the population dynamics of moths under the lamp, it could be applied to comprehensive prevention of moths in central Aksu area.
