Technical Abstract: The western corn rootworm is a major insect pest in continuous corn production, but no viable alternatives to insecticides are available for its control. Several seed companies have announced commercialization goals for transgenic seed with resistance to corn rootworm larval feeding, but sources of native resistance developed over the years have not been widely incorporated into the elite germplasm grown by farmers. A review of nativ resistance breeding programs will be presented along with a comparison of transgenic and native sources of resistance. Since corn rootworms are the target of more acres of insecticide than any insect pest, should transgenic sources of resistance be registered and/or native sources of resistance yield well enough, viable alternatives for corn rootworm control may have environmental as well as economic benefits.
