ABSTRACT
This chapter describes the importance of artificial selection experiments that provide the basis for improving the mass rearing methods of the melon fly. It discusses additive genetic variance in the melon fly, which causes a response to selection. The chapter reviews results of selection experiments in the melon fly. It discusses application of selection experiments to the mass rearing process. Genetic changes within the mass-reared strain of the melon fly, Bactrocera cucurbitae, have been an important consideration in the eradication project in Okinawa. Laboratory stocks are used for different applications after their characters have been affected by the genetic factors. Genetic variance of target traits is necessary to permit response to selection. Artificial selection is a useful tool with which the genetic basis of traits in insects can be evaluated.
