Screening for Resistance to Sorghum Shoot Bug and Spider Mites

Sorghum is one of the most important cereals in the semi-arid tropics. Nearly 150 insect specieshave been reported to damage the crop worldwide, causing an estimated loss of over US$ 1 000million annually. Of these, shoot fly, stem borers, greenbug, sugarcane aphid, shoot bug, spidermites, armyworms, midge, head bug, and head caterpillars are the major pests. Plant resistance toinsects is one of the most important components of pest management in sorghum. Thus, the 18specialist scientists who have contributed the 25 papers included in this book, that is based on atraining course for researchers involved in the development of insect-resistant cultivars for inte-grated pest management in sustainable agriculture, describe and discuss the theoretical and practi-cal aspects of resistance-screening techniques, mechanisms and inheritance of resistance, breedingfor resistance, statistical designs, and strategies for integrated pest management. Information hasalso been provided about the international sorghum insect resistance testing program and the roleof networks in collaborative research and technology exchange.
