摘要
甜菜夜蛾近年来在我国南方地区蔬菜和棉花上频繁暴发，尤其是７～９月发生严重。甜菜夜蛾在田间有大量的捕食性、寄生性天敌以及病原微生物，这些天敌包括捕食性天敌２５种、寄生性天敌６２种及病原线虫９种等，对甜菜夜蛾种群起着一定的控制作用，天敌种群的被破坏导致了甜菜夜蛾的暴发。本文综述了国内外目前对甜菜夜蛾天敌的调查研究和利用情况，对甜菜夜蛾防治中ＢＴ制剂和核多角体病毒的利用前景和存在问题进行了探讨。
Outbreaks of beet armyworm Laphygma exigua in vegetables and cotton in southern China occured frequently in recent years, mainly in July to September. It is, however, attacked by a large number of benefici predatory and parasitical arthropods and pathogens that appear to have some control effects on beet armyworm. This natural enemy complex include 25 predatory arthropods, 62 parasitoids and 9 entomopathogenic nematodes. Distruption of the complex contributes to outbreaks of beet armyworm. This paper reviews the worldwide investigation and application of beet armwworm natural enemies, and the applications of Bt and nuclear polyhedrosis virus and its problem in application are also discussed.
