| 摘 要： | 通过两年的研究,明确了太原地区甘蓝夜蛾年发生三代。第一代幼虫为害期为5～6月,第二代为害期为7～8月,第三代为害期为9～10月。室内用4种赤眼蜂对甘蓝夜蛾卵进行了抑制孵化试验,寄生率分别为:螟黄赤眼蜂97.68%,广赤眼蜂92.91%,玉米螟赤眼蜂80.90%,松毛虫赤眼蜂53.51%。甘蓝田、苤蓝田释放螟黄赤眼蜂、广赤眼蜂防治甘蓝夜蛾,5月份螟黄赤眼蜂寄生率68.76%,广赤眼蜂寄生率56.25%;9月份螟黄赤眼蜂寄生率92.82%,广赤眼蜂寄生率88.16%。使用化学农药防治的甘蓝田、苤蓝田均未发现有赤眼蜂寄生。

| Abstract: | Through two years of research,the occurred in three generations of Mamestra brassicae in Taiyuan region was defined.The first generation of larvae damaged from May to June,the second generation from July to August,the third generation from September to October.The indoor test used four kinds of Trichogramma to suppress Mamestra brassicae egg hatching,and parasitic rates were: Trichogramma chilonis 97.68%,Trichogramma evanescens 92.91%,Trichogramma ostriniae 80.90%,Trichogramma dendrolimi 53.51%.In the field test,parasitic rate of Trichogramma chilonis and Trichogramma evanescens were 68.76% and 56.25% in May;parasitic rate of Trichogramma chilonis and Trichogramma evanescens were 92.82% and 88.16% in September.Trichogramma parasites was not found by using chemical pesticides to control in cabbage fields. |
