摘要:

本文论述了生物防治与保护生物多样性的关系,提出生物多样性是生防作用物的必要来源,生物防治是保护生物多样性的重要措施。文中分析了自然界和农田生态系统中天敌的多样性和寄主专一性,并从外来种的治理、濒危物种和栖境的保护等几个方面探讨了生物防治对于保护生物多样性的作用。作者还强调应加强国际间天敌资源的交换,建立严格的天敌引种释放法规,以便开展更多的安全有效的生物防治项目。

Abstract

This paper discussed the relationship between biological control of pests and conservation of biodiversity, pointing out that biodiversity was the source of biological control agents, and in turn biological control of pests played an important role in conservation of biodiversity. It reported briefly the diversity of natural enemies and their host specificity in natural and agricultural ecosystem, and the roles of biological control in management of exotic species as well as conservation of endangered species and habitats. The authors also emphasized that international exchange of natural enemy resources should be widely supported and the code of conduct for the import and release of biological control agents should be earlier established in order to implement more safe and effective biological control programs.
