| 摘 要： | 为明确19种杀虫剂对桃小食心虫的防治效果,为卵期喷药防治该虫提供依据,用浸渍法进行了室内毒力测定。结果表明,19种供试药剂的毒力差异较大,拟除虫菊酯类杀虫剂溴氰菊酯、高效氯氟氰菊酯、甲氰菊酯、高效氯氰菊酯、氰戊菊酯及混剂甲维氯氰对桃小卵活性较高,其LC50均小于0.3 mg/L;其次为室内甲维盐、氟虫腈、灭幼脲、丁烯氟虫腈、毒死蜱、噻虫嗪、虫螨腈;阿维菌素、噻嗪酮、茚虫威较低;氯虫苯甲酰胺毒力最低。在桃小卵期树上施药,可优先选用杀卵活性较高的拟除虫菊酯类药剂,与具有杀幼虫活性、持效期长的灭幼脲和氯虫苯甲酰胺混用,可有效防治桃小食心虫。

| Abstract: | The toxicity of nineteen insecticides to the eggs of Carposina nipponensis Walsingham were detected by impregnation method.The results showed that the nineteen insecticides had great differences in toxicity.The pyrethroid insecticides such as decamethrin,lambda-cyhalothrin,fenpropathrin,beta-cypermethrin,fenvalerate and the mixed agent of emamectin benzoate and cypermethrin had relatively higher toxicity to the eggs of Carposina nipponensis Walsingham with LC50 lower than 0.3 mg/L;emamectin benzoate,fipronil,chlorbenzuron,butane-fipronil,chlorpyrifos,thiamethoxam and chlorfenapyr had moderate toxicity;avermectins,buprofezin and indoxacarb had lower toxicity,and chlorantraniliprole had the lowest toxicity.In conclusion,the pyrethroid insecticides should be preferred use and combined with the long-validity insecticides chlorbenzuron and chlorantraniliprole to control Carposina nipponensis Walsingham. |
