| 摘 要： | 川楝素是从川楝树分离得到的一种四环三萜类化合物。它对菜青虫有较强的拒食及毒杀作用,因此施药后能很快地得到保护叶片的效果,且在田间也有较长的残效期。经试验,川楝素对天敌凤蝶金小蜂及蚜茧蜂安全。

| Abstract: | A series of laboratory and field experiments were carried out in Guangzhou using toosendanin for the control of the imported cabbage-worm.Toosendanin was isolated from the bark of the chinaberry tree, Melia toosendan Sieb.et Zucc.in Sichuan Province.The sample for tes-ting contained 58% of pure toosendanin.Results showed toosendanin is a strong antifeedant as wellw as a stomach poison.A concentration of 100 ppm caused 80% mortality to the first instar larvae,and 400 ppm cau-sed 80.9% mortality to the third instar larvae in 4 days after applic-ation.Against the fifth instar larvae in the range of 300~2000ppm,with increasing concentrations,the amount of feeding markedly decreased and the mortality increased.(Fig.3). |
