La presente invención se refiere a aislados de Bacillus thuringiensis designados B. t. PS157C1, B. t. PS86A1 y B. t. PS75J1, que son activos contra plagas de ácidos. Así, estos aislados, o sus variantes, pueden ser usados para controlar esas plagas. Adicionalmente, se pueden retirar los genes que codifican ó-endotoxinas novedosas, de estos aislados, y se pueden trasferir a otros microbios o plantas anfitriones. La expresión de las ó-endotoxinas en anfitriones microbios, da por resultado el control de plagas de áfidos, mientras que las plantas transformada se vuelven resistentes a las plagas de áfidos. The subject invention concerns Bacillus thuringiensis isolates designated B.t. PS157C1, B.t. PS86A1, and B.t. PS75J1, which are active against aphid pests. Thus, these isolates, or variants 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 aphid pests, whereas transformed plants become resistant to aphid pests.
