赣东北地区的松毛虫卵寄生蜂综述

赣东北地区的松毛虫卵寄生蜂有 1 5种 ,其中有 3种是近年发表的新种。调查分析表明 ,赤眼蜂、黑卵蜂和平腹小蜂是主要类群 ;平腹小蜂属的白跗平腹小蜂是优势种。思茅松毛虫的卵寄生率明显高于马尾松毛虫 ,主要是个体大、寄生力强的平腹小蜂和金小蜂的寄生量大。若能造成多种卵寄生蜂及其它天敌增加的趋势 ,控制松毛虫成灾是完全可能的。

Egg parasitic wasps of pine caterpillars in the Northeastern area of Jiangxi Province

There are 15 species of egg parasitic wasps on pine caterpillars in the Northeastern area of Jiangxi Province,among which 3 species are described recently.The investigation and analysis show Trichogramma sp., Telenomus sp., Anastatus sp.are the main parasitoids, Anastatus albitarsis Asmead is the superior species.The egg parasitic rate of wasps. on Dendrolimus kikuchii is obviously higer than on D.punctatus (Walker).The cause is that the Anastatus sp.and the Pachyneuron sp. have large parasitic capacity,big bodies and strong parasitisms It is possible to control pine caterpillars if we can increase the population of egg parasitic wasps and other natural enemies.
