[Objectives]  To clarify how different host plants and foods affect the growth and development of Carpomyia vesuviana. [Methods]  The sexual maturity, fecundity and longevity of C. vesuviana fed on foods containing different proportions of honey, YE, and sugar, were measured and compared. In addition, the effects of different host plant fruits (jujube and apricot) on the fecundity, larval growth，pupal characteristics, rate of adult emergence, and offspring sex ratio were determined under indoor conditions at (30±1.0)℃，14L︰10D. [Results]  The four different foods significantly affected the sexual maturity, mating period, fecundity and longevity of adult insects. The pre-mating period, mating period, and egg-laying period, of adults fed on food B were 5 d, 5.2 h, 2.87 individual, respectively, and longevity was 38 d for females and 19.5 d for males. These results for food B are significantly different from those obtained for foods A, C, and D. Longevity of female insects that were fed on foods A and D were significantly different from each other but the longevity of those fed food C was not significantly different from those fed on foods A and D. Diet had no effect on the longevity of male insects. Twice and many oviposition marks were found on jujubes as on apricots. The length, width and weight of pupae on jujubes (4.01 mm, 1.67 mm and 4.6 mg, respectively) were significantly greater than those on apricots, and the rate of adult emergence and sex ratio were significantly lower on apricots (56.6% and 1.8︰1, respectively) than on jujubes (80% and 2.4︰1, respectively). The result of this study have practical significance for the prevention and control of C. vesuviana.
