| Abstract: | Both the standard Bacillus thuringiensis kurstaki (HD-1) and the formulated commercial product resulted from this strain have shown limited pathogenicity against the tobacco cutworm (Spodoptera litura). However, two new isolates of Bacillus thuringiensis (K-2074 and K-2178) isolated from Taiwan have been identified through an active screening program to be highly pathogenic against the tobacco cutworm. In this paper, we present results of characterization and the pathogenicity of these two new isolates. |
