金银花林下种植模式昆虫多样性研究

Study on Community Diversity of Insect in Honeysuckle Underwood Planting Pattern

目的:摸清北京市金银花林下种植模式的昆虫群落结构,为金银花害虫的绿色防控提供依据。方法:应用虫情测报灯进行监测,调查昆虫种类和数量,分析其多样性、种群动态等。结果:昆虫群落由7目21科50余种昆虫组成,其中,鳞翅目昆虫种类最多,为30种;鞘翅目次之,为10余种。鳞翅目、鞘翅目在数量上占整个昆虫群落的绝大多数,分别为30.26%、56.32%。5—9月为昆虫活动高峰期,在7月昆虫群落的个体数量达到最大值,4月和10月个体数量相对较低。8月、9月多样性指数较高,昆虫群落的物种多样性相对丰富。结论:上述结果为指导金银花综合防治提供了依据。

Objective： The purpose of this study is to verify the community diversity of insect in honeysuckle planting pattern,thus providing the basis for prevention and control of honeysuckle pests. Methods： Pest forecast lamp was used for monitoring,insect species and quantity was investigated,its diversity and population dynamics was analyzed. Results： The insect community consisted of 7 orders,21 families and more than 50 species. Among them,Lepidoptera was the dominant order which consisted of 30 species, Coleoptera came second which consisted of 10 species. Lepidoptera and Coleoptera accounted for the vast majority of the whole insect community in number,made up 30. 26% and 56. 32%,respectively. The peak period of the pest activities was from May to September,the individual number of insect community reached the maximum in July,the number of individuals was relatively low in April and October. The diversity index of insect community was high,species diversity was relatively rich in August and September. Conclusion： These results provide the basis for IPM in honeysuckle.
