      Abstract

      Bacillus thuringiensis, an entomopathogenic bacterium, produced spores and crystal proteins during sporulation. They were toxic to insect pests. B. thuringiensis subsp. wuhanensis possessed three types of crystal protein(Cry1Ab,1 Db, and mixing of CrylAb and Cryl Db), as their gene expression. The purpose of the research was to identify toxicity of the spores and crystal proteins of B. thuringiensis subsp. wuhanensis. The results showed that Type 2 (Cryl Db) was very toxic to Spodoptera litura while Type 1 (Cryl Ab) was more toxic to Plutella xylostella than S. litura.Type 3 was toxic only against S.litura.The bioassay of B.thuringiensis 'spores against P.xylostella showed that Type 2 was very toxic compared with two other types.
