| 摘 要： | 采用室内生测和田间小区试验相结合的方法,对秋季甘蓝进行了1%苦皮藤素微乳剂防治小菜蛾和菜青虫的生物活性研究。室内生测采用药浸法,结果表明:用1%苦皮藤素微乳剂对小菜蛾和菜青虫的3龄幼虫的LC50分别为0.980、.39 mg/L;而1%苦皮藤素乳油对小菜蛾和菜青虫的3龄幼虫的LC50分别为1.811、.01 mg/L。田间药效试验结果表明:1%苦皮藤素微乳剂稀释800~1 000倍防效较好,且药效持久,与1%苦皮藤素乳油相比,可减少原药用量的35%~40%。

| Abstract: | The method of biological test indoor and experiment in field was adopted in the paper,and the biological activity of Piutella xylbstella L.and Pieris rapae L.using 1% high osmotic Celangulins ME microemulsion was studied.The results of pesticide soak indoor biological test showed:LC_(50) of 1% Celangulins microemulsion against Piutella xylbstella and Pieris rapae with the age of three larvae LC_(50) was respectively 0.98 and 0.39?mg/L;but the LC_(50) of 1% Celangulins EC to Piutella xylbstella and Pieris rapae with the age of three larvae was respectively 1.81 and 1.01 ml/L.The medicinal effect in field showed:the medicinal effect of 1% Celangulins microemulsion diluted 800～1?000 times was better and longer than 1% Celangulins emulsive oil,which reduced the dosage of 35～40 percent in technical grade material. |
