梨小食心虫生物防治研究进展

Advances in research on the biological control of the oriental fruit moth

梨小食心虫Grapholita molesta(Busck)是世界性分布的果树主要害虫之一,可危害多种果树。多年来,过度依赖化学农药防治梨小食心虫效果并不理想,且杀伤天敌、污染环境、导致农药残留。利用自然天敌防治梨小食心虫高效、无毒、无污染,符合当前社会对环保的要求。本文结合前人工作,从病原微生物、寄生性天敌、捕食性天敌、性信息素、化学信息物质等方面,综述了梨小食心虫生物防治的研究进展,并对其应用前景进行了展望。

The oriental fruit moth, Grapholita molesta（Busck）, is a major pest of fruit crops worldwide that causes serious damage in most fruit-growing areas. Control of this pest has mainly depended on chemical pesticides which have undesirable side effects, for example, reducing the abundance of natural predators of pests and environmental pollution from pesticide residues. In contrast, using predators to control the oriental fruit moth is both effective, and produces no pesticide residues or other environmental pollution. This paper reviews previous research on biological control agents for the OFM, including pathogenic microorganisms, parasites, predators, sex pheromones, and semiochemicals. Potential future developments in the biological control of this pest are also discussed.
