摘要:

本文通过防治试验,提出了云杉阿扁叶蜂Acantholydapiceacola Xiao et Zhou的综合防治措施。研究认为,开展封山育林,改善林分环境,保护和利用天敌,是长期控制该虫害的根本措施。成灾区应采取多种措施,综合治理。在2龄幼虫期以25%灭幼脲3号胶悬剂100~150×液低容量喷雾一次,杀虫率在95%以上;卵孵盛期以飞机低容量喷洒25%灭幼脲3号(600g/hm2)与2.5%功夫乳油(105g/hm2)混配液一次,杀虫率达96%以上。

Abstract:

The control trail of Acantholyda piceacola was carried out by using insectcides, such as, Dimilin, Cyhalothrin, Deltamethrin etc., and the integrated control method of the Acantholyda piceacola was advanced in this paper. The results show that the essential way to control the pest in a long term is to carry out the measures of closing the forest, improving stand environment, protecting their natural enemies. The integrated control method should be used in harmed area. The death rate of the 2d instar larvae was over 95% by using Diflubenzuron No.3 25% (100×~500×). In the hatching peak period, the mortality could exceed 96% by using low volume aerial spraying once with mixed emulsion of 25% Diflubenzuron No.3 (600g/hm2) and cyhalothrin (105g/hm2)
