Abstract
The practice of growing varieties, lines, or summary hybrids resistant to attack by insects, and their subsequent effectiveness in reducing pest populations and corresponding crop losses, is well documented for several agricultural crops and pest species. The development of many of these resistant cultivars has resulted from or been facilitated by (1) mary years of study of the insect pests, (2) the development of techniques to mass rear the insects, artificially infest the crop species, and screen the germplasm of the species (or their wild relatives) for resistance, and (3) the successful application of appropriate breeding procedures for improvement of the resistance characteristic over succeeding cycles or generations of population improvement (Guthrie, 1974, 1980).
