豆天蛾是我国黄淮地区夏大豆的主要害虫,近几年来连年为害,普遍严重.1985年,安徽省阜阳地区豆天蛾成虫大发生,后经作者定株系统调查,发现豆天蛾卵寄生率达90%以上,其中黑卵蜂(Tele-nomus spp) 寄生率达82.1%,是豆天蛾卵寄生蜂的优势种群,有效地控制了豆天蛾幼虫的发生量.因此,在制定大豆害虫的综合治理策略和措施中,应重视豆天蛾卵寄生蜂的发生数量,注意加强保护和利用. 掌握黑卵蜂种群寄生豆天蛾在一定环境内的空间分布结构,有助于进一步了解其生活习性与环境条件的关系,选用相应的田间取样技术和调查资料的数理统计代
Bean moths are the main pests of summer soybean in Huanghuai region of China, which have been seriously damaged in successive years in recent years. In 1985, the adults of bean moths occurred in Fuyang area of Anhui Province. After investigation by the authors, The parasitism rate was more than 90%, and the parasitism rate of Tele-nomus spp was 82.1%, which was the dominant population of the eggs parasitoid, and effectively controlled the occurrence of larvae. In the comprehensive control strategies and measures of soybean pest, we should pay more attention to the occurrence of egg parasitic wasps, and pay more attention to the protection and utilization.Controlling the spatial distribution structure of the parasitoids, Understand the relationship between their habits and environmental conditions, select the appropriate field sampling techniques and survey data on the generation of mathematical statistics
