上海地区花卉节肢动物群落组成调查

2006年2月至2007年1月对上海地区60余种花卉生境中节肢动物群落组成进行了调查,把采集的节肢动物按营养关系分为植食类、捕食类、寄生类、其它类等4个功能团。根据鉴定结果,植食类共121种,捕食类22种,寄生类12科,其它类13科。其中,16种节肢动物为上海地区首次报道。植食类、捕食类、寄生类和其它类的相对丰富度分别为78.10%、5.61%、2.44%和13.85%。保护花卉生境中的捕食性和寄生性天敌种类是花卉生产生态化管理的重要任务之一。

An investigation of arthropod community composition in ornamental plants habitat in Shanghai

We investigated the arthropod community composition in the habitat of more than 60 species of ornamental plants in Shanghai from Feb.2006 to Jan.2007.Arthropods were sorted into guilds, which were phytophages,predators,parasitoids and others.Based on the classification,there were 121 species of phytophagous arthropods,22 species of predators,12 families of parasitoids and 13 families of others.In our studies,16 arthropods were first reported in Shanghai.The relative abundance of phytophages,predators,parasitoids and others were 78.10%,5.61%,2.44% and 13.85%,respectively.One of the ecological management measures was to protect predators and parasitoids arthropods during vegetative cycle of ornamental crops.
