摘　　要：应用饲料重量的0.2%、0.4%、0.8%的棉酚浓度,在室内饲养雄性蟑螂(德国小蠊:Blat-tella germanica L.)结果表明:0.8%的棉酚对雄性蟑螂有明显的雄性不育作用,幼虫孵化率比对照减少92.9%;0.4%棉酚对雄性蟑螂有一定的雄性不育作用,幼虫孵化率比对照减少41.3%;SSR检验表明,三种浓度之间不育效果差别明显。不育雄虫可能有一定竞争交配的能力。该方法为蟑螂的防治中减少种群数量开辟了新途径。The sterility effect of 0.2%,0.4%,0.8% of gossypol sterilant to the male Blattella germanica L. in the laboratory was studied.The results showed that the sterility effect of 0.8%,0.4% of gossypol sterility was significant. The incubation rate of the larvae＇s decreased respectively 92.9%, 41.3% than CK. The SSR test showed that the sterility effect of hree kinds of concentrations of gossypol was significant different. The sterile males may have mating competition ability. It is a new method for the decrease of population of Blattella germanica L. in the laboratory.
