Stalk-boring and leaf feeding lepidoptera are major pests of maize worldwide. Improvement of plant resistance to these pests is an objective of public maize research groups at international, federal, and state institutions. These institutions have played important and unique roles in the development of insect rearing techniques, efficient methods for infesting and evaluating germplasm for resistance, screening germplasm to identify sources of resistance, and the release of resistant germplasm to the public. Commercial seed companies have become the primary institution for developing new lines and hybrids in the USA and Europe. Private seed companies, both international and domestic, are also becoming important seed suppliers for the rest of the world. For these reasons, the introgression of insect resistant sources into elite germplasm has required the transfer of knowledge and resistant sources from public to private institutions. The development of multiple borer resistant hybrids illustrates the value of good institutional linkages in the improvement of maize.
