Among numerous insects which attack maize, Zea mays L., stem borers are ubiquitous and major pests. These lepidopterous insects infest the maize crop throughout its growth from seedling emergence to maturity. Maize in every country and type of crop cultivation is usually infested by one or more stem borer species. The use of borer resistant maize varieties is an ideal method of managing these pests. Breeding for stem borer resistance has become a major research objective in most of the maize growing countries of Africa, Asia, and the Americas. Success in breeding for stem borer resistance depends upon the development of effective and efficient techniques for screening germplasm for sources of resistance. Screening techniques were presented at the first CIMMYT symposium on developing insect resistant maize in 1987. After sources of resistance have been identified and developed to some usable form (i.e., inbreds), the mechanism(s) and bases of resistance should be determined to fully understand the nature of the resistance and how to best use the resistance source in breeding programs and the resistant cultivars in integrated pest management programs. This paper serves as a review of some entomological techniques which have been used to determine mechanism(s) operating in resistant plants and to elucidate the chemical and/or physical factors (bases) responsible for resistance.
