Zusammenfassung:	Compositions and methods for controlling plant pests are disclosed. In particular, transgenic maize plants comprising nucleic acid molecules encoding modified Cry3A toxins having increased toxicity to western corn rootworm are provided. Such modified Cry3A toxins, into which a non-naturally occurring protease recognition site is inserted, are expressed at levels in transgenic plants to inhibit insect feeding damage and cause insect mortality.
