【摘要】 :对杨小舟蛾 [Micromelalopha troglodyta ( Graeser) ]的化学防治、微生物制剂防治和人工防治试验结果表明 ,应用 40 %氧化乐果乳油 2 0 0 0倍、40 %水胺硫磷乳油 15 0 0倍、2 0 %速灭杀丁乳油 30 0 0倍、2 5 %灭幼脲 2 0 0 0倍液防治杨小舟蛾幼虫 ,均可取得良好效果 ;B.t+氧化乐果具有增效作用 ,其中 B.t+氧化乐果 ( 40 0 +60 0 0倍 )防治效果最好 ;人工除蛹对杨小舟蛾具有一定的防治效果。化学农药防治最佳时期为第 2代幼虫期。更多还原

【Abstract】 The results of experiment on control of small prominent Micromelalopha troglodyta ( Graeser) show that it is the most effective to control larves of second generation of M.troglodytawith chemicals,including spray of40 % folimt at2 0 0 0 dilution,2 5% diflubenzurn at 2 0 0 0 dilution,and other two kinds of chemicals. Spray of B.t emulsion & forlimat is the best way to control small prominent,and artificial killing of pupa also effective way to control it.更多还原
