| abstract |
Disclosed and claimed are Bacillus thuringiensis isolates designated B.t. PS45B1, B.t. PS24J, B.t. PS94R3 B.t. PS17, B.t. PS62B1 and B.t. PS74G1 which are active against acarid pests. Thus, these isolates, or mutants thereof, can be used to control such pests. Further, genes encoding novel delta -endotoxins can be removed from these isolates and transferred to other host microbes, or plants. Expression of the delta -endotoxins in microbe hosts results in the control of acarid pests, whereas transformed plants become resistant to acarid pests. |
