摘　　要：为筛选出高效安全的植物油类杀虫剂,采用标准土壤法比较了精制松树油、棕榈油、精制松树油与棕榈油混合油等3种植物油和二甲苯为助剂配制的1%甲维盐EC对赤子爱胜蚯蚓(Eisenia foelide)的室内毒力,同时测定了4种药剂对小菜蛾(Plutella xylostella L.)的田间药效试验.结果显示:棕榈油配制的1%甲维盐EC毒性低于二甲苯配制的1%甲维盐EC,因此棕榈油替代二甲苯配制的1%甲维盐EC提高了对蚯蚓的安全性.精制松树油+棕榈油基1%甲维盐EC 0.90 L/hm^2剂量处理在药后7 d的防效尤为显著,且优于相同剂量的二甲苯基1%甲维盐EC处理的防效.In order to select safe and efficient plant oil pesticide, the toxicities of emamectin benzoate mixed with three plant oils （pine oil, palm oil, pine oil with palm oil） and xylene to earthworm （Eisenia foelide） were investigated by the standard soil test, and the filed efficacy with four pesticides to controll pluteUa xylostella were determined. The results showed that the acute toxicity of emamectin benzoate mixed with the palm oil to earthworm was lower than that of the emamectin benzoate mixed with xylene and having higher safety for earthworm. The emametin benzoate mixed with pine oil and palm oil had excellent effect with 0.90 L/hm^2 treatment after 7 days for controlling plutella xylostella, and it had better control effect compared with the emamectin benzoate mixed with xylene.
