番茄潜叶蛾及其他4种番茄常发害虫的高效兼治药剂筛选
Effective Pesticide Screening for Common Control of Phthorimaea absoluta and Other Four Pests of Tomato
摘要
Abstract
After the tomato leaf miner(Phthorimaea absoluta Meyrick)invaded China,a trend of this pest occurring together with other four common pests,including Liriomyza sativae Blanchard,Bemisia tabaci Gennadius,Thrips palmi Karny and Tetranychus urticae Koch,which posed great threats to the safety produc-tion of tomato in China.In order to screen out the pesticides simultaneously controlling P.absoluta and the oth-er 4 pests,the toxicity of 16 common pesticides to P.absoluta larvae,L.sativae larvae,B.tabaci adults,T.palmi adults and T.urticae adults were determined to comprehensively analyze the simultaneous treatment of these pesticides.The results showed that the pesticides with higher toxicity(LC50＜5.0 mg a.i./L)to P.abso-luta larvae were chlorantraniliprole,abamectin,spinetoram,cyantraniliprole,clorfenapyr,emamectin benzo-ate and tetrazolamide.The pesticides with high toxicity(LC50＜18.0 mg a.i./L)to P.absoluta and L.sativae were cyantraniliprole,spinetoram,abamectin,chlorfenapyr,chlorantraniliprole,emamectin benzoate and tet-razolamide.The pesticides with high toxicity(LC50＜28.0 mg a.i./L)to P.absoluta and B.tabaci were cyan-traniliprole,thiamethoxam,abamectin and emamectin benzoate.The pesticides with high toxicity(LC50＜24.0 mg a.i./L)to P.absoluta,L.sativae and B.taboci mainly included cyantraniliprole,abamectin and emamectin benzoate,which also had high toxicity(LC50＜7.0 mg a.i./L)to T.palmi.Abamectin and emamectin benzoate showed higher toxicity to the five pests with the LC50 of 0.22～9.24 and 0.80～6.90 mg a.i./L,respectively.In toma-to production,the co-treatment pesticides should be chosen according to the species and harm degree of tomato leaf miner and other pests,and their alternate use should be noted.关键词
