Technical Abstract: Insects have historically been, and continue to be, one of the more destructive groups of organisms that feed on corn. More recent studies also indicate that they are important in promoting mycotoxin problems in corn. A combination of breeding and genetic engineering has greatly reduced the problems with many of the insects that are important pests of corn. There is also evidence that the generically engineered corn hybrids that are resistant to insects have reduced levels of mycotoxins compared to their nonresistant counterparts. However, insect pest complexes, weather conditions, and inherent hybrid resistance to insects or fungi can influence the relative value of genetically engineered resistance in reducing mycotoxins. The dynamic evolutionary relationship between insects, corn, and their environment are likely to continue to create challenges for those attempting to develop more insect-resistant corn.
