云南酸甜石榴园Malaise网诱捕昆虫群落及其季节性动态*

 2007～2008年，以云南省建水县酸石榴园为基地，采用Malaise网诱捕器对园内昆虫群落结构进行了调查，根据节肢动物群落中物种的营养和取食关系将总群落划分为天敌亚群落、害虫亚群落、中性昆虫亚群落，利用群落多样性指标对石榴不同生育期昆虫群落结构及其动态进行了分析比较。结果表明，从2007年5月～2008年9月，共诱捕获得昆虫纲12目75科375种1708头。物种丰富度、多样性指数和均匀度分别为5025，508，086。其中寄生性天敌有79种300头，捕食性天敌有46种162头，害虫有193种959头，中性昆虫有57种287头。害虫亚群落、天敌亚群落和中性昆虫亚群落物种丰富度分别为2796，2021，989，多样性指数分别为423，436，326。天敌昆虫群落与害虫群落及中性昆虫群落相对多度呈互补关系

Seasonal Structure and Dynamics of Insect Communities Trapped by Malaise Trap in Pomegranate Orchard

The community structure of insect communities in sweet soul pomegranate orchard was surveyed by using the Malaise trap in pomegranate orchard in Jianshui county, Yunnan province, China. Results showed that, there were 1708 insects belonging to 12 orders and 75 families of insect captured in the Malaise trap from May, 2007 to the September, 2008. The richness and Shannon Wiener index and Evenness index was 5025, 508, 086, respectively. Among of them, there were 79 species of 300 individuals were parasitoid, there were 46 species of 162 individuals of predator, and 193 species of 959 individuals of pest insects of pomegranates. The species richness was 2796, 2021, 989 for pest insects, natural enemies and neutral insects, respectively, and the ShannoJP6]n WJP]iener index was 423, 436, 326, respectively. The abundance of the natural enemies was complementary with the pests and neutral insects in the pomegranate orchard.
