Abstract: An isolation method was developed with comparing different selective culture media and 54 Bt strains were isolated from 25 species of plants in China. The bioassay was conducted by use of Ectropis obliqua, Empoasca vitis and Acaphylla theae as target insects. It showed that there were 10 strains effective to Lepidoptera and 4 to Homoptera but they were all ineffective to Acaphylla theae mites.
