摘要
选择了３种化学药剂对湿地松粉蚧进行室内杀虫试验及林间防治，结果表明：在室内低浓度下（稀释４０００倍）以速扑杀效果最好，平均校正死亡率达８４．４７％；林间用速扑杀能较快地降低当代虫口密度，对湿地松粉蚧的扩散蔓延起到一定的抑制作用。
Three kinds chemical on controlling Oracella acuta were tested in laboratory and in field as well. Low concentration of methidathion is the best and the average corrected death rate was up to 84.47%. The effect in the forest field shows that the methidathion can quickly reduced the population density of the pest and prevented it from spreading.
