The composition and preparation of an artificial diet for the coffee berry borer, Hypothenemus hampei is described. Ten generations were obtained without any significant change in fecundity. Development at 25-degrees-C on this diet was similar to previously reported work using coffee berries. One female reared on this diet lived for 380 days. This diet will permit investigations into the genetics of insecticide resistance, potential biopesticides and other research, requiring a convenient laboratory rearing system.
