摘　　要：【目的】在杏树树体流动花芽膨大前,吐伦球坚蚧越冬代若虫体背开始产生蜡丝时,筛选出合适的药剂进行田间防治。【方法】用20种药剂对介壳虫若虫进行室内药剂筛选,并选择室内防效好的药剂进行田间防治试验。【结果】室内筛选出16种药剂,在药后第6 d其防效都大于90%,选择了其中11种药剂进行田间防治试验,药后12 d顺式氯氰菊酯1 500倍+甲维盐2 500倍混剂、蚧必治1 000倍液、金速扑杀+3%0#柴油及高效氯氰菊酯微乳剂+3%0#柴油防效均可达97%以上;毒死蜱+3%0#柴油、蚧虫毒1 000倍液、8Be石硫合剂、滴一滴8 000倍液、阿克泰4 000倍液的防效也可达94%以上。【结论】11种药剂对吐伦球坚蚧越冬代若虫均具有较好的防治效果。【Objective】Before the apricot flower formation and serictery silk gland appear from Rhodococcus turanicus Arch nymph wintering,the suitable pesticides were screened and selected to be used for preventing and controlling Arch nymphs in the field.【Method】The 20 different kinds of pestcides in the lab were selected to have better control efficacy in field to control scales nymph.【Result】In the labs 16 kinds of pesticides were selected,after 6 days,the result indicated that the efficacy would be over 90%;11 pesticides were used in field,after 12 days treatment,the result of field trials showed that the control effeicacy of mixture alpha-cypermethrin 1 500 times＋emamectin benzoate 2 500 times,jiebizhi 1 000 times,mathidathion＋3%0#diesel and cypermethrin ＋3%0#diesel reached over 97%,the control efficacy of chlorpyrifos＋3%0# diesel,jiechongdu1 000 times,8Be lime sulfur,imidacloprid 8 000 times thiamethoxam 4 000 times were over 94%.【Conclusion】These kinds of pesticides have better efficacy to control Rhodococcus turanicus Arch nymph.
