【摘要】 甜菜夜蛾是蔬菜等多种植物的重要害虫 ,现在已成为一个急需解决的问题。已有报道表明甜菜夜蛾抗药性迅速增加是导致其在我国频繁暴发的主要原因。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 ,这些对甜菜夜蛾种群的控制起到很大的作用 ,所以生物防治对于防治甜菜夜蛾来说至关重要。本文综述了国内外近些年来甜菜夜蛾天敌、病原真菌以及病原微生物的调查研究和利用情况 ,并对甜菜夜蛾防治中植物提取物和性引诱剂等的利用现状作了探讨。更多还原

【Abstract】 Beet armyworm (Spodoptera exigua Hb.) is an important pest on many vegetable crops and its control has recently become a critical concern.Outbreaks of the pest have been attributed to development of insecticide resistance.There are a large number of natural predators,parasites,and pathogenic microbes that appear to provide some control of beet armyworm,and thus biological control seems to play an important role in its control.This paper reviews the status of research and utilization both inside and outside China of natural enemies,pathogenic fungi,and pathogenic microbes as well as plant extracts and sex attractants in controlling beet armyworm.更多还原
