It was determined as a new serotype H70 by agglutination tests. Parasporal crystals were bipyramidal shape and contained two proteins of 135kD and 130kD. Strain YK30 04 showed lower toxicities to the larva of Plutella xylostella and Prodenia litura, whereas no activities to the larva of Tenebrio molitor and Culex fatigans. Thus the strain YK30 04 was identified as a new serovar: Bacillus thuringiensis subsp. sinensis.展开更多
