European corn borer is not only a major pest on all types of corn, but it also causes losses in several other crops. For some crops subjected to unusually high infestations, the economic losses can amount to hundreds of dollars per acre. Larvae of European corn borer infest more than 200 species of plants. Research has been ongoing in its ecology, genetics, and diversity, and in how to manage it. Studies indicate that European corn borer is one of the most adaptable and hard to predict insects. Thus, adaptation to new hosts is constantly occurring and impact on its current crop hosts seems to change constantly. This broadly diverse species also continues to evolve new genetic strains that present new problems and challenges to scientists. In the past few years, a higher incidence of infestation has been found in cotton, wheat, and apple shoots than was found previously. Also, recent research has shown that the E pheromone type often is associated with several early crops in the eastern United States, such as potato and wheat. It would not be surprising to discover that this insect is genetically adapting to become more of a problem on wheat in the eastern and midwestern United States and to cotton in the southern states.
