| 摘要: |
| 在研究、开发和使用新型植物性杀虫剂的过程中,以菜青虫为主,对苦楝、川楝树皮中的呋喃三萜类物质——川楝素,从药效、致毒机理、使用技术以及剂型加工工艺等方面做了10多年的研究。这种植物性杀虫物质可破坏菜青虫的中肠组织,并引起一系列生理病变。用楝树皮提取物为主要成份加工配制成0.5％楝素杀虫乳油,取名“蔬果净”,已正式投入生产。该剂安全、高效,使用后无毒害残留,尤适于经济作物上防治有害昆虫,是配合“无污染”蔬菜、果品、茶叶、烟草、中草药等作物生产的良好药剂。 |

| Abstract: |
| In the process of study,development and application of a new type of botanical insecticides, studies on a triterpenoid from the bark of chinaberry Melia toosendan and Melia azedarach in medical effectiveness,mechanical toxicology,application techniques and dosage processing technology have been, for more than 10 years,conducted with Pieris rapae L. in the main. This kind of botanical insecticides can cause damage to the midgut tissue and a series of physiological changes in Pieris rapae L. The atracts from the bark of chinaberry as the main component have been prepared into Toosendanin 0. 5 EC named as "Shuguojing",having been put into normal production. This botanical insecticide is safe and effective and free of toxic residuals and adaptable to controlling pests over industrial crops and also,a good inseticide in matching with the pollution -free production of vegetables,fruits,tea,tobaco,and medcial herbs. |
