2007年7—8月对洱海周边的下关、大理、喜洲、上关、双廊、挖色、海东、满江的水稻抽穗期稻田蜘蛛及昆虫资源进行了初步调查,共采集的节肢动物13225头,其中害虫2879头,害虫天敌2211头,鉴定结果显示:洱海周边地区水稻抽穗期稻田害虫有10种,隶属4目6科8属,害虫天敌46种,隶属5目18科27属。其中,挖色、上关、双廊、喜洲、下关、满江、海东和大理地区的害虫物种分别占整个洱海周边地区水稻抽穗期稻田害虫物种总数的80%、80%、70%、70%、50%、50%、50%和40%;害虫天敌分别为52%、50%、46%、46%、41%、39%、37%和35%。
During July to August, 2007, the resources of spiders and insects were preliminary investigated for the rice heading stage of Xiaguan, Dali, Xizhou, Shuanglang, Wase, Haidong and Manjiang areas. 13225 inarthropods were collected, among of these, pest 2879, pest natural enemy 2211. The result shows： there are 10 pests, belong to 4 orders, 6 families and 8 genera; in addi- tion, pest natural enemy 46, comprised 5 orders, 18 families and 27 genera. Among of them, the species richness of pest in Wase, Shangguan, Shuanglang, Xizhou, Xiaguan, Manjiang, Haidong and Dali occupied respectively80% , 80% , 70% , 70% , 50% , 50% , 50% and40% , respectively, and the pest natural enemy52% ,50% ,46% ,46% ,41% ,39% , 37% and35%.
