    Abstract: The subject invention concerns materials and methods useful in the control of pests and, particularly, the plant pests. More specifically, the subject invention concerns novel genes and pesticidal toxins referred to as 86A1(b) and 52A1(b). In preferred embodiments, the subject toxins are used for controlling flea beetles of the genus Phyllotreta. Using the genes described herein, the transformation of plants can be accomplished using techniques known to those skilled in the art. In addition, the subject invention provides toxin genes optimized for expression in plants.
