菜青虫的生物防治技术

The Biological Control Technology of Pieris rapae Linne

菜青虫为菜粉蝶的幼虫,在我国各地均有分布,且为害极为严重。对于菜青虫的防治一般采用化学防治的方法,但该方法易造成害虫抗性上升、环境污染和农药残留等问题。为避免此类问题的发生,笔者详细介绍了菜青虫的生物防治技术,包括病原微生物和天敌昆虫的应用,以期为菜青虫的有效防控提供新的途径。

Pieris rapae Linne distribut- ed in various regions in China, and its damage was also serious. The general control method of Pier,s rapae Linne was chemical control method, but it was easy to cause some problems, such as pest re- sistance increasing, environmental pollu- tion, pesticide residues and so on. To avoid these problems, the biological control technology of Pieris rapae Linne was introduced in this paper, including the application of pathogenic microor- ganism and natural enemy insects, in or- der to provide a new way for effective control of Pieris rapae Linne.
