摘要
经调查,蚕豆田的昆虫和蜘蛛,计有68种,其中属农作物害虫的有18种,天敌有50种。本文还对蚕豆田节肢类的优势种群、种群动态及其群落特征进行了分析,阐明了保护蚕豆田中的天敌对控制后茬作物害虫的重要意义。
The species of Anhropoda in the broad bean feids of Wuchang were investigated in 1985-1986. It was found that there are 68 species of Anhropoda, 50 species of which are benificial kinds, 18 species of which are destructive species. Among them, 4main species of pests, Aphis craccivora, Empoasca flavescens, Bruchus rufimanus, Aulacophora femoralis chi-nensis, and 8 main species of natural enemies, Stenus macies, Paederus fuscipes, Verania discolor. Neoscona Doenitzi, Misumenopos tricuspidata, Theridion octomaculatum, Aphidus si-fuensis, and Diaeretiella rapae were recorded.The quantitative dynamics of main pests and natural enemies in the broad bean fields was analysed, and the community characteristics of pests and natural enemies in the broad bean fields, such as the food web in the broad bean field, the main kinds of the community and the dynamics of community were discussed. The important significance was expounded on protecting the natural enemies of the broad bean fields to control the pests of aftercrops.
