Sorghum, maize and cowpea serve as staple food for people in Africa and are grown mostly by small-scale farmers. A major constraint on the production of these crops is attack by insect pests among which crop borers are most important, causing 30–80

Once a resistant cultivar is developed, the hope is that the resistance which has been selected is durable. One way of making sure that the resistance obtained lasts long is the development of multiple resistance.The International Institute of Tropic
