中文摘要： 柑橘矢尖蚧Unaspis yanonensis (Kuwana)是危害柑橘的重要害虫之一。为了筛选高毒有机磷农药的替代物，在室内条件下采用浸渍法分别测定20种杀虫剂原药对柑橘矢尖蚧1龄若虫的毒力。结果表明：供试杀虫剂对柑橘矢尖蚧的毒力大小依次为：甲氨基阿维菌素苯甲酸盐＞阿维菌素＞硝虫硫磷＞噻嗪酮＞杀扑磷＞吡虫啉＞乙酰甲胺磷＞毒死蜱＞喹硫磷＞亚胺硫磷＞稻丰散＞敌百虫＞残杀威＞氟氯氰菊酯＞甲氰菊酯＞甲氧虫酰肼＞苯氧威＞高效氯氰菊酯＞石硫合剂＞矿物油。
英文摘要：Unaspis yanonensis (Kuwana) is one of the important insect pests in the orange production process. To select the pesticide which can replace the organophosphorus pesticide with high toxicity, the toxicities of 20 kinds of common pesticides applying against U. yanonensis were determined by the means of soaking under laboratory conditions. The order of toxicities of the 20 insecticides from high to low against the first instar larva of Unaspis yanonensis Kuwan was emamectin benzoate＞abamectin＞xiaochongliulin＞buprofezin＞methidathion＞imidacloprid＞acephate＞chlorpyrifos＞quinalphos＞phosmet＞phenthoate＞trichlorfon＞propoxur＞cyfluthrin＞fenpropathrin＞methoxyfenozide＞fenoxycarb＞beta-cypermethrin＞lime sulfur＞petroleum oil.
