摘　　要：利用天然植物去创制新型杀虫剂已成为目前农药研究的热点。本文研究发现 ,太白山区的白藓皮具有良好的杀虫活性 ,对蟋蟀、蚱蜢的死亡率达 10 0 % ,对三龄粘虫的拒食率为 87 8% ,死亡率为 83 3% ,这表明白藓皮有望成为新的植物杀虫剂。Making use of natural plants to create new insecticides has become a heated topic of the study of pesticides recently The insecticidal activity of Cortex dictamni of Taibai Mountains has been studied,its toxicity determination indicates that Cortex dictamni has fine insecticidal power,the death rate to grasshoppers and crickets is up to 100%,then the antifeed rate to 3rd instar Mythimna separata (Walker) is 87 8% and its death rate 83 3%,the one will become the new biorational pesticides
