3种杀虫剂对韭菜迟眼蕈蚊的亚致死效应
Sublethal Effects of Three Insecticides on Bradysia odoriphaga
摘要
Abstract
In this study,we tested the toxicities of dinotefuran,beta-cypermethrin and thiamethoxam on 3-instar larvae of Bradysia odoriphaga by stomach-contact method,and analyzed the LC30 (mg/kg) of three pesticides.After treated with LC30 concentration of pesticides for 48 hours,the surviving 3-instar larvae of Bradysia odoriphaga were raised in non-toxic petri dish,and the pupation rate,weight of male and female pupal,eclosion rate,ratio of female to male,egg number per female and egg hatching rate were observed.The results showed that dinotefuran had the highest toxicity in the three pesticides,with the LC30 value as 9.02 mg/kg,followed by thiamethoxam (15.24 mg/kg) and beta-cypermethrin(16.28 mg/kg).The three pesticides inhibited the development and propagation of Bradysia odoriphaga in different degrees.Beta-cypermethrin inhibited the growth of larvae,dinotefuran reduced the egg hatching rate of filial generation,and thiamethoxam decreased the egg number per female obviously.关键词
