摘　　要：测定了甲基嘧啶磷、四溴菊酯、DDVP3种保护剂对面粉、烤烟饲养的烟草甲的室内触杀毒力。结果表明:3种保护剂对烟草甲触杀活性的大小依次为:四溴菊酯>甲基嘧啶磷>DDVP;不同食料对烟草甲幼虫的药剂敏感性也产生变化。The contacting toxic ability of pirimiphos-methl, thralomethric and DDV to the tobacco beeries, Lasioderma serricome （Fabricius）was tested. Two different diets in the laboratory were raised and these recursive equations of their toxic ability and the LC50 were respectively gained. The results showed that the gradation of toxic ability of the three protection pesticides acting the cigarette beetle was： thralomethric 〉 pirimiphos-methl 〉 DDVP. Besides, the different diets had influenced the pesticide susceptibility obviously.
