| 摘 要： | 2006年7～9月,用五点抽样法对新疆石河子农耕区不同植被类型中的昆虫群落结构进行调查,共采集到昆虫68种,隶属10目34科,共计6727头,其中叶蝉和蚜虫是主要害虫,瓢虫和草蛉是主要天敌昆虫。群落结构分析表明:在不同植被类型中昆虫群落多样性显著不同,以苗圃的多样性指数最高(2.5739),玉米的最低(1.0189),果木类的高于农作物的,间作的高于单纯植物的。

| Abstract: | The diversity characteristics of insect community structrues in different types of vegetations in Shihezi agriculture cultivation area were studied by sampling method in five spots from July to September. Sixty-eight kinds of insects species were collected in this investigation, which are belonged to ten orders, thirty-four families. Among them, Jassidae and Aphididae are the main injurious insects and Coccinellidae and Chrysopidae are the primary natural enemies. The researching results show that the diversity index of insect community of nursery is the highest, that of corn-land is the lowest, that of fruit tree is higher than that of crop and that of intercrop vegetation is higher than that of pure vegetation. |
