【Abstract】 In Qingzhou City of Shandong Province,carbosulfan 10 g(a.i.)/667?m2,p-metolcarb 15?g(a.i.)/667?m2,metolcarb 12.5?g(a.i.)/667?m2,o-metolcarb 12.5?g(a.i.)/667?m2 showed larvicidal activity of 91.13%～91.14%,89.66%～91.66%,89.29%～91.36% and 87.82%～88.83% respectively in field trials on leaf-miner,Liriomyza sativae, on aubergine plants after 3～7 days.These substances were quick acting and had good residual performance.N-methyl-3-ethylphenyl carbamate 12.5?g(a.i.)/667?m2,macbal 15?g(a.i.)/667?m2,meobal 15?g(a.i.)/667?m2,hercules 15?g(a.i.)/667 m2 showed a control efficacy of 80% or so on pumpkin.The efficacy of p-metolcarb 20?g(a.i.)/667?m2 WP were 84.93%～85.47% on cucumber in Haidian district,Beijing.On different host plant,the adjusted mortality of β-carbaryl was over 85%.carbosulfan,p-metolcarb,metolcarb,o-metolcarb and β-carbaryl are effective pesticides for the control of L.sativae.更多还原
