烟青虫是我省辣椒的主要害虫。幼龄幼虫为害辣角,使辣角变质,一般年份损失率为15％。目前生产上多采用滴滴涕为主的药剂防治,效果不显著。为了提供经济、安全有效的防治措施,于1980—1981年我们用拟澳洲赤眼蜂的三个生态型,在杨陵公社东魏店对烟青虫进行了防治试验。每种生态型的释放面积均在4亩以上,以药剂防治或不放蜂处理作为对照,每亩放蜂量3万头,分两次释放。放蜂后2日收回人工挂卵卡同时采烟青虫卵,进行寄生率观察,半月后
Tobacco caterpillar is the main pest in our province pepper. Young larvae harmful spicy angle, so that the hot angle deterioration, the general annual loss rate of 15%. The current production of more DDT-based pharmaceutical control, the effect is not significant. In order to provide economic, safe and effective prevention and control measures, we used the three ecotypes of Trichogramma ostriniae from 1980 to 1981 to test the control of tobacco budworms in Dongwei Branch of Yangling Commune. The release area of each ecotype is more than 4 acres, with the chemical control or not put the bee treatment as a control, the bee release amount of 30,000 mu, divided into two release. On the 2nd after the beekeeping recovery of artificial hanging egg card at the same time smoking caterpillar eggs, the parasitic rate of observation, a half months later
