摘  要:
首次报道美国白蛾Hyphantria cunea(Drury)的一种捕食性天敌——蠋敌Arma chinensis(Fallou),简述了蠋敌的生物学特性。在商河县,蠋敌在美国白蛾幼虫网幕枝中的分布率为2.33%~17.86%;记述了蠋敌的捕食习性和规律,经室内饲养,统计出各龄若虫和成虫的捕食量,从若虫到成虫,最大捕食量为2头3龄、7头4龄、5头5龄、23头6龄共37头白蛾幼虫;最小取食量为4头2龄、8头3龄、1头4龄、1头5龄、2头6龄共16头白蛾幼虫;分析并指出蠋敌对美国白蛾具有较强的控制能力,是自然界中影响美国白蛾种群密度的重要因子。

摘  要:
A predatory natural enemy of Hyphantria cunea(Drury),Arma chinensis(Fallou),is reported firstly.Biological characteristics,preyed habits and regulation of Arma chinensis(Fallou) was descriped.Distributiong rate of Arma chinensis(Fallou) in web branches of Hyphantria cunea(Drury) larvae is 2.33%~17.86%.The most preyed mount were 37 heads Hyphantria cunea(Drury) larvae through indoor rearing,2 heads of 3 instar,7 heads of 4 instar,5 heads of 5 instar,23 heads of 6 instar,respectively.And the least preyed mount were 16 heads Hyphantria cunea(Drury) larvae through indoor rearing,4 heads of 2 instar,8 heads of 3 instar,1 heads of 4 instar,1 heads of 5 instar,2 heads of 6 instar,respectively.The result showed that control ability of Arma chinensis(Fallou) to Hyphantria cunea(Drury) was strong.Arma chinensis(Fallou) was important factor to effect population density of Hyphantria cunea(Drury) in nature.
