为筛选出用于防治棕榈蓟马的有效药剂,北京市植保科技人员近期采用玻璃残留处理法测定了5种药剂对蔬菜上棕榈蓟马的室内毒力,并进行了田间药效试验。室内毒力测定结果表明,杀虫活性最高的是乙基多杀菌素,其48小时的LC50值为0.19mg/L;其次是阿维菌素、溴氰虫酰胺和啶虫脒,LC50为54.45~76.48mg/L,呋虫胺的毒力最低。田间试验结果表明,6%乙基多 To screen out effective agents for the prevention and treatment of Thrips tabaci, Beijing plant protection scientists recently used glass residual treatment method for the determination of five agents on vegetables Thrips tabaci indoor toxicity and field efficacy trials. The results of indoor toxicity test showed that the highest insecticidal activity of spinetoram, 48h LC50 value of 0.19mg / L; followed by avermectin, bromoxetine and acetamiprid, LC50 was 54.45 ~ 76.48mg / L, the lowest toxicity of dinotefuran. Field test results show that 6% ethyl more
