Effects of rearing density of larvae and adults on the production rate of Dacus cucurbitae were examined for the improvement of mass production techniques. The relationship between metabolic heat produced in larval diet and the rearing density was presented by a linear regression. At the egg density more than 4ml per 2l laval medium, temperature of the medium reached 33.5℃ and this results in harmful effect on larvae and pupae. There was anegative linear relationship between the pupal weight and the rearing density. The recovery of pupae reached 69.7%, when the rearing density was 0.5ml eggs per 2l larval medium, and 93.4% in case of 1.0ml eggs per medium, but it decreased when the egg density was more than 2.0ml per mebium. We consider that the optimum rearing density is approximately 2,0-2.5ml per 2l medium. Population productivity seems to be the highest when adults were reared at a density of 30,000 individuals per cage
