Abstract: The toxicities of six strains of Bacillus thuringiensis (belonging to four serotypes) to Ostrinia furnacalis (toxic indicator insect) and Heliothis armigera HÜbner,Mythimna separata Walker and Euxoa segetum SchiffermÜller were tested and compared, and the correlation between the toxic indicator insect and the other three kinds of insect was also determined. Suppose the toxic index of the tested strains to O. furnacalis is 0.The toxic indices to H. Armigera, M. separata and E. segetum are 0.647±0.074, 0.268±0.070 and 0.145±0.031, respectively. So the sequence of B. thuringiensis is O. furnacalis>H. armigera>M. separata>E. segtum.

Key words: Bacillus thuringiensis, Ostrinia furnacalis, Heliothis armigera, Mythimna separata, Euxoa segetum, Toxic indicator insect
