摘要
Chouioia cunea Yang is a natural enemy for many kinds of crop and forest pests, particularly for Hyphantria cunea Drary, which is an international quarantine pest. The experiment of rearing Chouioia cunea with Tussah (Silkworm) pupa were carried out by 搕hree-cut method?and inoculating method. The results showed that three-cut method is effective way for breed-ing Chouioia cunea, with a parasitical rate of 95%. The biological characteristics and the life cycle of Chouioia cunea were ob-served and described and more hosts of Chouioia cunea were found. 揟hree-cut method?as a new technique of rearing Chouioia cunea has been put into practice.
白蛾周氏啮小蜂是许多种农林害虫的天敌,尤其是对美国白蛾(HyphantriacuneaDrary)这种世界性检疫害虫效果更为显著。本实验利用三刀法和接种法通过柞蚕蛹人工大量繁殖白蛾周氏啮小蜂。结果显示,三刀法对于繁殖白蛾周氏啮小蜂是非常有效的,达到95%的寄生率。我们观察和描述了白蛾啮小蜂的生物学特性和生活史,并且发现了更多的寄主。三刀法作为饲养白蛾周氏啮小蜂的一种新技术已经被推广和应用。图4表1参5。
