【摘要】 本文分别采用浸渍法和药膜法生物测定了48%乐斯本乳油、4.5%高效氯氰菊酯乳油、10%吡虫啉可湿性粉剂、90%敌百虫原药和1.8%阿维菌素乳油5种药剂对番石榴果实蝇老熟幼虫、蛹及成虫的毒力。结果表明,供试药剂对番石榴果实蝇的毒力大小依次为48%乐斯本乳油>4.5%高效氯氰菊酯乳油>10%吡虫啉可湿性粉剂>90%敌百虫原药>1.8%阿维菌素乳油。认为这5种药剂可作为防治番石榴果实蝇的候选药剂。更多还原

【Abstract】 The toxicity of several insecticides including the 48% lorsban EC,4.5% beta-cypermethrin EC,10%imidacloprid WP,90 % trichlorfon and 1.8% abamectin EC on the mature larvae,pupae and the adult of B.correcta was evaluated by using the dip method and residual film bioassay method.The results showed that the toxicity of the tested insecticides to the B.correcta(Bezzi) was ranked of 48% lorsban EC>4.5% beta-cypermethrin EC>10% imidacloprid WP>90% trichlorfon>1.8% abamectin EC.The pesticides can be the alternative insecticides for the control on the guava fruit fly.更多还原
