Cowpea aphid (Aphis craccivora Koch) is a major pest of cowpea (Vigna unguiculata L. Walp.) particularly in the drier regions of the tropics. Although aphid resistant varieties had been developed, resistance has recently broken down. The present study seeks to identify new sources of resistance. ...
