| 摘 要： | 扁座壳孢(Aschersonia placenta Berk.et Br.)是黑胶粉虱病原真菌,在寄主初龄幼虫期使用孢子悬浮液喷雾,个体容易感病,而且致死力较强。该菌最适生长温度24—26℃,暴发性流行季节气候条件多阴雨,相对湿度在85％以上。病原能在一般培养基上生长繁殖。在自然界以感病致死虫尸为营养载体,粘附在叶面,不断形成分生孢子,产生再次侵染,对控制害虫虫口增长作用显著,是综合防治中不可忽视的生物因素。 |

| Abstract: | Aschersonia placenia Berk, et Br. is a parasitic fungus of the white fly Aleurotrachelus camellia Kuwana. In applicating spore suspensions of the fungus to the pest, in its young stage it has shown great pathogenieity.The optimum temperature for growth of the fungus is between 24—26℃. The epizootics of the fungus usually occur in rainy season when R. H. is above 85%. The fungus can grow on some common media.In nature, the fungus persists and sporiilates on the bodies of infected insects. The organism can reinfect its hosts and thus reduces the pest population. It is a biotic agent which should not be neglected for the integrated pest management. |
