ABSTRACT:
Disclosed 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 produce novel .delta.-endotoxins active against acarid pests. Thus, these isolates, or mutants thereof, can be used to control such pests. Claimed are genes encoding these novel .delta.-endotoxins, which can be removed from these isolates and transferred to other host microbes, or plants. Expression of the toxins in microbe hosts results in the control of acarid pests, whereas transformed plants become resistant to acarid pests.
