摘要
对新疆南部喀什地区莎车县恰热克镇棉田及相邻荒漠过渡带寄生性天敌昆虫群落结构及动态进行了初步的研究和分析,寄生性天敌在棉田中共有14科,荒漠过渡带共有21科。在棉田中蚜茧蜂数量最多,占总数的19.86%;荒漠过渡带中无后缘姬小蜂数量最多,占总数的34.93%。荒漠过渡带的寄生性天敌群落的丰富度、多样性指数均比棉田高,均匀性指数总体来说比棉田低。棉田中寄生性天敌昆虫和相邻荒漠过渡带中寄生性天敌昆虫关系密切。荒漠过渡带为棉田提供了丰富的寄生性天敌资源。
This article carries out a preliminary research and analysis on community character of the parasite natural enemy insects in desert transition zone and its adjoining cotton field in the south of Xinjiang, 14 families of parasite natural enemy were collected and indentified in the cotton field, and 21 families in the desert transition zone.Aphidiidae is maximum species in the cotton field, 19.86% of the total species number of parasite natural enemy insects in the cotton field , and Tetrastichidae is maximum in the deserts transition zone, 34.93 % of the total species number of parasite natural enemy insee in the deserts transition zone. The results showed that the numerical values of richness and diversity of the parasite nature enemies in the desert transition zone were higher than those in the cotton field, and the value of E was lower than that in the desert transition zone. There is a close relationships between the parasity natural enemy insects in desert transiction zone and its adjoining cotton field. This clearly indicated that the desert transition zone provided resource of the parasite natural enemy insect for the cotton field.
