中文摘要： 采用浸叶法比较了外来入侵物种西花蓟马Frankliniella occidentalis （Pergande）与本地物种烟蓟马Thrips tabaci Lindeman对辛硫磷、毒死蜱、高效氯氰菊酯、多杀霉素、甲氨基阿维菌素苯甲酸盐和阿维菌素6种杀虫剂的敏感性。结果显示：西花蓟马对辛硫磷、毒死蜱和多杀霉素的敏感性均比烟蓟马明显要高，而高效氯氰菊酯和阿维菌素对烟蓟马则具有较高的毒力。多杀霉素对西花蓟马和烟蓟马的防治效果最好，在药剂浓度为0.5 mg/L时，2种蓟马的校正死亡率均超过90%。
英文摘要： The susceptibility of invasive Frankliniella occidentalis (Pergande) and native Thrips tabaci Lindeman to phoxim, chlorpyrifos, betacypermethrin, spinosad, emamectin benzoate and avermectins was compared under laboratory conditions using the dip method.The results indicated that F.occidentalis was significantly more susceptible to phoxim, chlorpyrifos and spinosad than T.tabaci but T.tabaci was more susceptible to beta-cypermethrin and avermectins.In addition, we found spinosad was effective for controlling both F.occidentalis and T.tabaci; the corrected mortality of both these thrips was over 80% at a concentration of 0.5 mg/L active ingredient
