摘  要：
通过阳性(含Arsenophonus)与阴性(不含Arsenophonus)褐飞虱初羽化成虫的正反交试验,发现子代感染Arsenophonus的情况由其母本决定,而与父本无关,表明褐飞虱体内的Arsenophonus可由母体垂直传递给子代。初羽化阳性和阴性成虫的配对实验结果表明,Arsenophonus对褐飞虱后代数量及性比没有显著的作用,无雄性致死作用。通过黄绿绿僵菌ARSEF1764菌株对初羽化雌成虫褐飞虱的接种实验,发现阴性试虫的感病率为55.2%,显著高于阳性试虫的32.5%,表明感染Arsenophonus有助于提高褐飞虱对黄绿绿僵菌ARSEF1764菌株的抵抗能力。

摘  要：
According to direct and reciprocal cross test,Arsenophonus offspring infection was determined by female parents rather than male parents,which indicated Arsenophonus was maternally inherited in the brown planthopper(BPH),Nilaparvata lugens.The newly emerged Arsenophonus-infected(positive)and-uninfected(negative)BPH were paired respectively,the number and sex of offsprings were recorded.The results indicated Arsenophonusinfection did not significantly impact reproduction and sex ratio of BPH.It suggested that Arsenophonus had no male-killing function to BPH.The results showed that the infection rate of negative population to M.anisopliae ARSEF1764(55. 2%)was significantly higher than that of positive population(32.5%),which indicated Arsenophonus could improve the resistance of BPH to M.anisopliae.
