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
