发展和利用天敌控制森林害虫的增长是防治森林害虫一个重要途径。几年来,由于天敌的作用,舞毒蛾在敦化林区柞树林内虽然保持着一定的数量,但并未成灾。为了准确地掌握天敌的种类,更好地发展和利用天敌资源,特对敦化林区内舞毒蛾幼虫天敌进行了调查。视步收集到舞毒蛾天敌昆虫7种,其中有寄生蜂6种、捕食性天敌1种。简述如下: Apanteles sp.属膜翅目,姬蜂总科,茧蜂科,绒茧蜂属。该蜂是小型蜂,蜂幼虫寄生于寄主幼虫体内,蜂幼虫成熟后结茧于寄主体外。茧白色,圆筒形,绒状,群集于寄主之旁
Developing and using natural enemies to control the growth of forest pests is an important way to combat forest pests. In recent years, due to the role of natural enemies, Gypsy moths maintained a certain amount in the oak grove of Dunhua forest area, but they did not cause any disasters. In order to accurately grasp the types of natural enemies and to better develop and utilize the natural enemy resources, we conducted a survey on the predators of the gypsy moth larvae in Dunhua Forests. Seven kinds of natural enemies of Gypsy moth were collected as follow, including 6 kinds of parasitic wasps and 1 kinds of predatory natural enemies. Briefly described as follows: Apanteles sp. Is a Hymenoptera, Scabis Division, Braconidae, velvet bee. The bee is a small bee, bee larvae parasitize in the host larvae, bee larvae mature cocoons after the host outside. Cocoon white, cylindrical, velvet, clustered in the host next to
