当一种外来害虫在一个新的地区定居下来后,通常采用的第一道防线是从该害虫的地方性地区引进天敌。这一策略被称为经典生物防治,可提供相当高水平的成本效益控制(货车den Bosch等人,1985年)。传统的昆虫生物防治常常强调引入拟寄生物和捕食者,虽然也使用病原体,但程度较有限(Fuxa 1987)。
After an introduced insect pest becomes established in a new area, the first line of defense often employed is to introduce natural enemies from the area of endemism of that pest. This strategy, termed classical biological control , can provide substantial levels of cost-effective control (van den Bosch et al. 1985). Classical biological control of insects frequently has emphasized the introduction of parasitoids and predators, although pathogens have also been used, but to a more limited extent (Fuxa 1987).
