摘要:

综述了近年来甜菜夜蛾Spodoptera exigua (Hübner)、寄主植物和寄生蜂互作关系方面的研究进展。介绍了甜菜夜蛾取食诱导的植物抗虫性产生的原因和机制;阐述了诱导植物产生抗性的甜菜夜蛾激发子volicitin的合成途径和功能,以及虫害诱导的植物挥发物和蛋白酶抑制剂对甜菜夜蛾及其寄生蜂的生态学功能;展望了植物诱导抗虫性在甜菜夜蛾的生物防治和新型抗虫品种开发等领域的应用前景。

Abstract:

The interactions of host plants, the beet armyworm Spodoptera exigua (Hübner), and its natural enemies was summarized. The mechanism and inducement of plant inducible resistance induced by the beet armyworm were introduced. The author clarified the synthesis and function of volicitin that elicits herbivore-induced plant volatiles, and the characteristics and ecological function of herbivoreinducible plant volatiles and wound-induced defense proteins in regulating the interactions of host plants, the beet armyworm, and its parasitoid natural enemies. The roles of plant inducible resistance in biological control of the beet armyworm and the research exploring new resistant varieties of crops in future were also discussed.

Key words: Spodoptera exigua, host plant, parasitoid wasps, tritrophic interactions, plant resistance to insects, bio-control
