摘　　要：应用害虫种群系统的理论和方法,以苏云金杆菌(Bt)、赤眼蜂(Techogrammerconfursam)、性诱剂为基本措施,辅以小菜蛾颗粒体病毒(PlutellaxylostellaGranulosisvirus,PxGV)、爱比菌素(Abamectin)和印楝素等非化学杀虫剂,组配成9种生态控制配套措施,评价其对小菜蛾的控制作用。其中7套措施可将小菜蛾种群趋势指数(I)持续控制在1.0以下,不同地区可合理选择使用。The 9 kinds of Ecological measures to control diamondback moth (DBM), Plutella xylostella (L.) were constituted based on cultivable and biological control methods, such as Bt, T. confursum and sex pheromone, PxGV, Abamectin and, neem oils from October, 1997 to December, 1998 in Dongguan City, Guangdong Province. The effects of the 9 kinds of ecological measures against DBM were evaluated. The results indicated that 7 of the 9 kinds of ecological measures played effective roles in suppressing the population densities of DBM. The indexes of population control were below one. The seven ecological measures could be selected in different regions in need of control DBM.
