从海州常山(Clerodendron trichotomum Thunb.)鞘锈菌(Coleosporium clerodendri Diet.)的夏孢子中分离出一种头孢霉,对其形态和生物学特性进行了研究,鉴定为Cephalosporium purpurascerts var.uredini-cola var.nov.(变紫头孢霉嗜锈品种),该菌对海州常山鞘锈菌有较强的破坏性,在高湿条件下,如霉雨季节或多露天气,对夏孢子寄生率达80％以上.又从蚜虫上获得2株轮枝菌,并鉴定为Verticillium lecanii(Zimm)Viegas(蜡蚧轮枝菌),该2菌株在高湿条件下对菊小长管蚜(Macrosiphoniella sanborni Gilletfe),菜缢管,蚜(Rhopalosiphum pseudbridssicae Dayis)和挑蚜(Myzus persicae Sulzer)均有致病力.
A strain of Cephalosporium was isolated from the summer spores of Coleosporium clerodendri Diet. The morphological and biological characteristics of Cephalosporium purpurascerts var. Provenini-cola var.nov. (Corynebacterium alkalophylla var. rust), the bacteria on the Haizhou habitat rust hardy have strong destructive, under high humidity conditions, such as the rainy season or more exposed weather, the rate of uredospores Up to more than 80% .And two strains of Verticillium lecanii (Zimm) were obtained from the aphids. Verticillium lecanii (Verticillium lecanii) was isolated from Macrosiphoniella sanborni Gilletfe, Rhizoctonia solani, Rhopalosiphum pseudbridssicae Dayis and Myzus persicae Sulzer.
