Gamma irradiation of the western cherry fruit fly for the sterile male control technique

Creator:: Brown, Robert David
Abstract:: The western cherry fruit fly, Rhagoletis indifferens Curran, was studied to determine the suitability of the sterile insect technique for its control. To obtain insect material, field collection of maggots is preferred to sifting of soil or rearing on artificial diet. The western cherry fruit fly is strictly univoltine; only...
