摘　　要：采用5种不同浓度的森得保粉剂对马尾松毛虫和焦艺夜蛾幼虫进行喷粉防治试验,结果表明:森得保∶轻质碳酸钙为1∶13～1∶22的配比浓度,喷粉后12天防效均可达90%以上,同一浓度对两种害虫防治效果相近,对不同虫龄药效差别不明显,生产中建议采用1∶19～1∶22配比浓度,既经济又有效,可大面积推广应用。Five different concentrations of Sendebao,a dust pesticide,were sprayed against the larva of Dendrolimus punctatus and Hyssia adusta in the forest.The results showed that Sendebao raw dust and light calcium carbonate which mixed in the concentration ratio of 1∶13 to 1∶22 had a good control effect reached over 90% on the pests after used 12 days.They had a similar control effect against the two pests at the different ages in the same proportion.In fact,it’s effective and economic to promote the use of large area in the proportion of 1∶19 to 1∶22.
