摘要
从内地黄脊竹蝗自然病死虫尸内分离到一种病原菌,其纯培养物经KOCK病症律证明,并按《伯杰细菌鉴定手册》(第九版)的方法进行了生物学测定、生理生化实验,并测定了其DNA中G+Cmol含量为63.73％,确定该病原物为类产碱假单胞菌(Pseudomonas pseudoalcaligenes)。经生物测定,该菌对草地蝗虫和黄脊竹蝗有较强的感染力,对草地其他害虫也有一定的感染力。
A pathogen Was isolated from natural dead pests of Ceracris kiangsu in Geleshan farm of Chongqin. Its pathogenecity was comfirmed by the law of KOCK. It was identified as Pseudomonas pseudoalcaligenes according to its physiological and biochemical properties as well as the G+C content of DNA (63. 73mol%). The results of preliminary bioassay show that the pathogen can infect the grasshoppers and Ceracris kiangsu , and also can infect other pests of grassland in a certain extent.
