不同管理措施对杏园昆虫群落结构的影响

为全面了解杏树林害虫的危害与发生规律,为综合防治提供依据,应用生物多样性指数分析了英吉沙县不同管理措施杏园生态系统中昆虫群落结构特征.结果表明:在3种类型的杏园中有昆虫37种,分别隶属于9目26科;不同杏园昆虫群落的科数、物种数及丰富度均有不同程度的变化;不同生境集中性指数也有一定的差异;各园的优势种主要以剌吸式口器的朝鲜球坚蚧为主;不同杏园昆虫群落及各类群生态优势集中性在不同时段并不一致.

Research of Structural Aspect and Space??time Trends of the Apricot TreeStand Yard Insect Community on Different Management

For the sake of finding out the laws of insect pest damage to apricot trees and providing the basis for controlling the pest, sample plot method was applied to investigate the apricot tree stand. The diversity and insect community in different intercropping and managing apricot tree stand yard ecosystems in Yingjisha were studied. The results showed that there were 37 species of insects belonging to 9 orders and 26 families in different apricot tree stand yard ecosystems in Yingjisha. The number of orders and species and individual were not the same in different apricot tree stand yard ecosystems. In different ecosystems, the proportion of principal insect community groups was different, so that the diversity and evenness and dominant concentration index were not the same. Annual dominant species in each apricot tree stand yard was mainly Didesmococcus koreanus. The dominant concentration index of insect community and its principal groups was not the same in different time and apricot tree stand yards.
