The Development of Botanical Insecticides——Toosendanin

Zhang Xing Wang Xinglin Feng Juntao(Department of Plant Protection,Northwestern Agricultural University,Yangling,Shaanxi,China,712100)Chili Shin-Foon(Laboratory of Insect Toxicology,South China Agricultural University,Guangzhou,China,510642)  
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 M. 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.
