麻点豹天牛化学防治试验研究

A Study on the Chemical Control Methods to Coscinesthes salicis

    摘要
  • 摘要: 经多种农药、剂量、防治方法的反复比较,筛选出树干涂刷、注干、喷雾、喷烟等多种较理想的麻点豹天牛防治方法和措施:应用5%氯氰菊酯乳油、25%保得乳油分别与柴油1:150倍混合药剂进行树干涂刷,麻点豹天牛卵及幼龄幼虫防治死亡率达80%以上,最佳防治时期为产卵期及幼虫孵化期;应用5%氯氰菊酯、25%保得乳油分别与柴油1:75倍混合药剂喷烟防治成虫,死亡率达85%以上,最佳防治时期为9月上旬至11月中旬;树干注药是该虫整个幼虫期较为有效的防治方法。

     

    Abstract: Four chemical methods have good control effects to Coscinesthes salicis.Besmearing the trunk with the mixture,5% Cypepmethpin oil emulsion or 2.5% Bera-cyfluthrin oil emusion and diesel oil in the proportion of 1:50,may kill more than 80% of the eggs and newly hatched larvae.Using the mixture of 5% Cypepmethpin or 2.5% Bera-cyfluthrin oil emusion and diesel oil as smoke emission to control the adults,may kill 85% of the adults.The best time for this method is from early September to middle November.In addition,injecting chemicals to the trunk is an effective control method to all instar larvae.
