从江苏省连云港市云台山林区天然罹病死亡的日本弓背蚁幼虫体内分离出１株产生伴孢晶体的芽孢杆菌Ｌｙ３０株。该菌株具周生鞭毛，产生的伴孢晶体为钝菱形、不规则形和晶体镶嵌，且具显著晶格。聚丙烯酰胺凝胶电泳结果表明，伴孢晶体由１３５～１８５ｋＤａ的特殊多肽组成。经生化和血清学鉴定，该菌株属苏云金杆菌鲇泽亚种，血清型７（Ｂａｃｉｌｕｓｔｈｕｒｉｎｇｉｅｎｓｉｓｓｕｂｓｐ．ａｉｚａｗａｉ，ｓｅｒｏｔｙｐｅＨ７），对赤松毛虫、柏毛虫、玉米螟、菜青虫等幼虫有明显的致病性，尤其对赤松毛虫具有很高的毒力
A strain of Bacillus lycopersici producing Lycopersicum (Lycopersicon esculenta) strain Lycopersicon esculenta was isolated from the Japanese armyworm larvae that died of natural disease in Yuntai Mountain Forest Area, Lianyungang City, Jiangsu Province. The strain with periplasmic flagella, sporulation produced spongiform rhomboid crystals, irregular shape and crystal mosaic, and with significant crystal lattice. Polyacrylamide gel electrophoresis results show that the sporozoite crystal from 135 ~ 185kDa special polypeptide composition. The strain was identified as Bacillus thuringiensis subsp. Aizawai (serotypeH7) by the biochemical and serological methods. It showed obvious pathogenicity to larvae such as Dendrolimus punctatus, cypress, corn borer and cabbage caterpillars, especially Red cedar has a high toxicity
