采用浸叶法,在室内测定了5种杀虫剂对北京地区黏虫的毒力。结果表明,甲氨基阿维菌素苯甲酸盐对黏虫3龄幼虫的毒力最高,氯虫苯甲酰胺和虫螨腈次之,毒死蜱和氯氟氰菊酯的毒力较低。建议在黏虫应急防控中应用甲氨基阿维菌素苯甲酸盐、氯虫苯甲酰胺或虫螨腈(延庆除外),以提高防治效果。
The leaf dipping method was used to determine the toxicity of five pesticides to the armyworm in Beijing. The results showed that the emamectin benzoate had the highest toxicity to the 3rd instar larvae of the armyworm, followed by the chlorantraniliprole and chlorfenapyr, and the virulence of chlorpyrifos and cyhalothrin. Proposed application in the prevention and control of sticky worm methylamino abamectin benzoate, chlorantraniliprole or chlorpheniramine (except Yanqing), in order to improve the control effect.
