【摘要】 用抗性高粱饲养高粱蚜Melanaphis sacchari(Zehntner)的结果表明,高粱的抗生性影响蚜虫的生殖力和死亡率,田间抗性植株上蚜量少的原因就是与其上的蚜虫生殖力低、死亡率高有关,而且对子代的作用比母代大。更多还原

【Abstract】 As the sorghum aphid Melanaphis sacchari (Zehntner) was reared onsorghum leaves of resistant varieties tested in incubator,its mortalitywas increased and fecundity was decreased.There was more inhibitionon the progeny than on their parent aphid.It was suggested that thelower aphid population occurred in resistant sorghum field was associ-ated with the antibiosis on aphid development and reproduction.更多还原
