为比较溴氰虫酰胺和氯虫苯甲酰胺对甜菜夜蛾、玉米螟和小地老虎的作用差异,山东农业大学植物保护学院科研人员近期采用浸卵法、浸叶法、饲喂毒营养液法等,测定了溴氰虫酰胺和氯虫苯甲酰胺对3种害虫的卵、3龄幼虫和成虫的毒力,以及对其3龄幼虫的拒食活性。结果表明,溴氰虫酰胺和氯虫苯甲酰胺均无杀卵作用,但能降低初孵幼虫存活率。溴氰虫酰胺对甜菜夜蛾、玉米螟和小地老虎3龄幼虫的LC50值分别为0.11、
In order to compare the difference of the effects of Bromocarbide and Chlorantraniliprole against beet armyworm, Ostrinia furnacalis and Landrace, researchers at Plant Protection College of Shandong Agricultural University recently adopted the method of soaking eggs, dipping leaves and feeding toxic nutrient solution Method, the toxicity of 3, 3 instar larvae and adult adults of bromoxetane and chlorantraniliprole and the antifeedant activity against 3rd instar larvae were determined. The results showed that both bromothiramide and chlorantraniliprole did not kill eggs, but could reduce the survival rate of newly hatched larvae. The LC50 values of bromothrin for 3rd instar larvae of beet armyworm, Ostrinia furnacalis and Landrace were 0.11,
