摘　　要：采用“Y”形嗅觉仪研究二斑叶螨Tetranychus urticae Koch对接骨木(Sambucus williamsii Hance)、苹果(Malus pumila Mill.)、木瓜(Chaenomeles sinensis Koehne)、苦楝(Melia azedarach L.)、火炬树(Rhus typhina Torner)、大叶黄杨(Euonymus japonica Thunb)6种植物的嗅觉选择性差异。结果表明,该螨对苹果叶片的气味表现明显的趋向性,对木瓜叶片的气味表现明显的忌避性,而对其余4种叶片无趋向性或者表现中性。采用海绵水盘法研究在6种植物上的生长发育差异,该螨在接骨木、苹果、苦楝、火炬树上均能正常生长发育至成螨,且具有一定的繁殖力。但在木瓜和大叶黄杨上发育状况较差,繁殖力较差。Using “Y” olfactometer, we studied the olfactory response of Tetranychus urticae Koch odors from six plants species. Odors from Malus pumila Mill. were attractive to the mite and odors from Chaenomeles sinertsis Koehne were repel mites. Odors from the rest plants had neither attraction nor repulsion to the mite. Growth of T. urticae on six plants were studied by means of the leaf-dish rearing method. This mite could grow successfully from larva to adult on Sambucus williamsii Hance, Malus pumila, Melia azedarach L. , Rhus typhina Torner and had the high ability of reproduction. But growth from larva to adult on Chaenomeles sinensis and Euonymus japonica Thunb. is bad and had the low ability of reproduction.
