为筛选出防治苹果全爪螨越冬卵的有效药剂，指导田间科学施药，通过室内和室外试验评价了8种杀螨剂对苹果全爪螨越冬卵的杀灭效果。结果表明：8种杀螨剂对苹果全爪螨越冬卵的杀灭效果均较低，其中杀卵效果最好的药剂是146 g／L 阿维·乙螨唑 SC，其29．20 mg／L 浓度处理室内外的校正死亡率分别为66．61％和60．77％；其次是110 g／L 乙螨唑 SC，其22．00 mg／L 处理的校正死亡率分别显著和不显著低于146 g／L 阿维·乙螨唑 SC。建议在早春用146 g／L 阿维·乙螨唑 SC 喷苹果枝干防治苹果全爪螨越冬卵。%In order to screen out effective acaricides and guide their application in field,the killing effect of eight acaricides on the overwintering eggs of Panonychus ulmi were tested indoor and outdoor.The results showed that all the eight acaricides had lower killing effect on the overwintering eggs of Panonychus ulmi,in which,146 g/L abamectin etoxazole SC had the best killing effect,and its adjusted death rates indoor and out-door reached 66.61% and 60.77% respectively at the concentration of 29.20 mg/L.The next was 110 g/L etoxazole SC with the adjusted death rates at the concentration of 22.00 mg/L being significantly and not signifi-cantly higher than those of 146 g/L abamectin etoxazole SC.It was suggested that 146 g/L abamectin etoxazole SC should be used to spray apple branches in early spring to kill the overwintering eggs of Panonychus ulmi.
