摘要
研究报道了危害鲁梅克斯K— 1杂交酸模的主要害虫种类及 3种主要害虫的生物学特性和防治方法。蓼龟象甲 1年发生 2代 ,主要以成虫在寄主根部附近土层中越冬 ,亦有少数蛹及老熟幼虫在寄主根内越冬 ,成虫咬食叶片 ,幼虫钻蛀于根部危害 ;黎叶蜂 1年发生 3代 ,以老熟幼虫在土内作茧越冬 ;甘蓝夜蛾 1年发生 2代 ,以蛹在田埂和根部附近土下 5～ 10cm深度越冬。可采取轮作、诱杀。
Three main pests on a forage Rumex hybrid K-1, their bionomics and control strategies in Xinjiang were studied. The results showed that Rhinoncus pericarpius , Ametastegia wuorentausi and Mamestra brassicae had 2, 3 and 2 generations per year respectively, and overwintered as adult, over mature larvae in cocoon and pupa respectively in the soil near the host in Urumqi region. The control strategies of crop rotation, lure moth with lamp and insecticide application were proposed.
