松毛虫长效阻杀剂试验研究

为了充分发挥阻隔法防治松毛虫等有上(下)树习性的林果害虫不污染环境、极少杀伤天敌的优点，有效提高现有阻隔制剂的杀虫持效期和防治效果，采用农药缓释技术和抗雨水冲刷技术研制出了松毛虫长效阻杀剂。防治松毛虫试验结果表明，其杀虫持效期长达250d，虫口减退率达到100％，对害虫天敌的影响极小。该技术将高效杀虫与保护环境和天敌有机地融为一体，能在确保森林、环境和生态安全的前提下，有效控制松毛虫等的猖獗危害。

THE STUDY ON THE ENDURING EFFECTIVE INSECTICIDE TO PINE MOTH

In order to completely develop the strong points of cutting-off method to the environment pollution and natural enemies in dealing with the forest destructive insects such as pine moth which crawls up and down the tree habitually, and to efficiently lengthen effective time of validity and prevention results of plant diseases and elimination of pests, the author develops the enduring effective insecticide to pine moth on the basis of both farm chemical gradual sending-off technology and rain brushing resistance technique.The technical index shows that its effective validity may last as long as 250 days and dropping rate of insects may reach as high as 100 percent with little side-off effect to the natural enemies. This technique is to combine the high efficiency of killing insects and protection of not only the environment but also of the natural enemies.Moreover, the technique can effectively control the rampant damages of pine moth with the premise of ensuring the safety of the forest, environment and ecology as well.
