摘　　要：选取8种化学农药对湿地松粉蚧Oracella acuta(Lobdell)幼虫进行室内毒力测定,结果表明:40%杀扑磷对湿地松粉蚧的室内毒杀力最强,LC50为0.0480 g/L;毒死蜱毒力最差,LC50为0.4026g/L。在8种农药中,杀扑磷、氧化乐果和吡虫啉对湿地松粉蚧均有较好的毒杀效果。Eight pesticides were selected to determine their toxicity against OraceUa acuta larvae in the laboratory. The result showed methidathion 40% had the strongest toxicity （LCso = 0. 0480 g/L）while the toxicity of Chlorpyrifos was the weakest （ LCs0 = 0.4026 g/L）. Among the 8 pesticides, methidathi- on, omethoate and imidacloprid had better poison effect against the larvae.
