Title: Comparison of Pathogenicity Parasporal Crystal Protein in some Bacillus thuringiensis
Abstract: The study has been carried out to acquire some basic informations about Bacillus thuringiensis for developing the microbial pesticide. Pathogenicity tests on three of B.thuringiensis var. aizawai, kurstaki, and dendrolimus were determined in two species of insects, H. cunea and B. moris. The pathogencity in varieties of B. thuringiensis against H. cunea and B. mori was depended on instar age of tested larvae. Bacillus thuringiensis var. dendrolimus, kurstaki, aizawai are arranged in order of pathogenicity against H. cunea and B. mori. In result Bacillus thuringiensis var. kurstaki was shown the most stable toxicity with respect to each instar of tested larvae.
