| 摘 要： | 用2年时间,在通辽市美国白蛾发生区研究了释放寄生性天敌昆虫周氏啮小蜂和赤眼蜂防治该害虫的效果和种群数量调控情况.结果表明:林间释放周氏啮小蜂对美国白蛾蛹的寄生率为69％、天敌总寄生率为92％、防治效果为87.4％,林间释放赤眼蜂对美国白蛾卵的防治效果为78.7％.利用天敌防治美国白蛾方法有利于其他天敌种群自然繁育,无抗...

| Abstract: | The control effect and the pest population regulation situation of releasing the parasitic natural enemy insects Chouioia cunea Yang and Trichogramma dendrolimi Matsumura were studied in the occurrence area of Hyphantria cunea in Tongliao City with the two-year experiment.The results showed that the parasitic rate of Chouioia cunea Yang released in the forest on the Hyphantria cunea pupae was 69%,the total parasitic rate of natural enemies was 92%,and the control effect was 87.4%.The control effect of releasing Trichogramma dendrolimi Matsumura in the forest on the Hyphantria cunea egg was 78.7%.The method of using natural enemies to control the Hyphantria cunea was conducive to the natural breeding of other natural enemy populations.That was non-resistant to drugs and pollution-free to control Hyphantria cunea population for a long time. |
