摘要为了调查蓝莓地害虫及天敌昆虫的分布情况，为害虫的科学防治提供理论依据，于2013年4月至10月利用马来氏网法对杭州蓝莓地的害虫及天敌昆虫的分布情况和多样性进行了系统的调查和分析。结果显示：昆虫群落结构丰富，蓝莓地有昆虫8目35科76种。其中，害虫有15种，相对丰盛度为0.1104，相对丰盛度在前三位的有：黄守瓜（0.0368）、叶蝉（0.0359）、果蝇（0.0195）；天敌昆虫15种，相对丰盛度为0.4268，相对丰盛度在前三位的有：长足虻（0.2782）、烟蚜茧蜂（0.0565）、黑小唇泥蜂（0.0333），捕食性天敌占主导地位。蓝莓地害虫的发生动态与天敌昆虫的发生动态基本一致，害虫的数量从4月份至9月份呈上升趋势，10月份降低，天敌昆虫的数量在4月份至9月份之间亦呈上升趋势，10月份降低，天敌昆虫的发生动态与害虫的发生动态在时间和数量上有明显的跟随关系；昆虫的多样性指数从4月至9月呈上升趋势，到9月份达到最高值（0.5243），随后下降。46801

Abstract

In order to provide theoretical basis for scientific control of pests in blueberry orchard, we used the method of Malaise Traps to systematically carry out an investigation and analysis about the distribution and persity of pests and natural enemies in blueberry orchard of Hangzhou. The result of investigation showed that the insect community was abundant，which including 8 order, 35 families, 76 species. Among them, the species of pest were 15, the relative abundance was 0.1104, the top three was Aulacophora indica(Gmelin)(0.0368),Cicadellidae(0.0359),Drosophila melanogaster(0.0195); the species of natural enemy were 15, the relative abundance was 0.4268,  the top three was Chrysozona rufipennis(0.2782),Aphidius gifuensis(0.0565), Larra carbonaria(0.0333) and the predatory natural enemy insects played a dominant role. The occurrence dynamics of pests and natural enemy insects is basically consistent, the number of pests from April to September is on the rise, and reduce in October; the natural enemies is the same as the pests. There are obvious pursuing relationships in time and quantity between the pests and natural enemies. The persity index of insects from April to September was on the rise, until September reached its highest (0.5243), then down in October.
