舞毒蛾黑瘤姬蜂等美国白蛾蛹期寄生性天敌昆虫研究进展

Research advance in the parasitic enemy insects of Hyphantria cunea Drury pupae,mainly Coccygomimus disparis Viereck

美国白蛾是危害猖獗的世界性检疫害虫,笔者介绍了该虫蛹期寄生性天敌昆虫的种类,在介绍其中7种优势寄生性天敌对美国白蛾越冬蛹和夏季蛹的自然寄生率、寄主蛹中羽化的子代数和性比等研究结果的基础上,系统综述了舞毒蛾黑瘤姬蜂的分布、寄主、寄生率、生物学特性和人工繁殖与利用等方面的研究进展。结合江苏省采用天敌昆虫开展生物防治的现状,探讨了应用舞毒蛾黑瘤姬蜂防治美国白蛾的研究方向与利用对策。

Hyphantria cunea Drury is the dangerous quarantine insect pest in the world. In this article,the parasitical enemy insects of H. cunea pupae were introduced in detail. Research results of the natural parasitism rate to overwintering and summer host pupae,number of offspring,female ratio of seven main parasitical enemy insects were introduced,and research progresses of distribution,hosts,parasitism rate,biology and artificial production technique of Coccygomimus disparis Viereck were also mainly reviewed systematically. Moreover,the practical situation of controlling pests to use natural enemies in Jiangsu was discussed and research direction and application strategy of controlling H. cunea to use C. disparis in the future were also explored.
