This study aims to determine the most suitable artificial diet for rearing the Oriental fruit fly Bactrocera dorsalis. The experiment was conducted by evaluating the growth and development parameters of the Oriental fruit fly when reared in the laboratory with four artificial diets with main ingredient: yeast (TA1), wheat bran (TA2), rice bran (TA3), and ground longan (TA4). The results showed that B. dorsalisfemales reared on TA2 had the shortest lifecycle (29.75 days), while there was no significant difference in lifecycle when reared on the three other diets, with 34.23 days (TA1), 34.28 days (TA3) and 34.27 days (TA4). The daily oviposition and total reproduction of the female adults reared on TA2 were the highest, with values of 13.11 eggs/day and 587.40 eggs/female, respectively, significantly higher than the other diets. The net reproductive rate (R0) and intrinsic rate of increase (rm) were also significantly higher than the other diets. R0decreased in the order of TA2 (320.73), TA3 (264.55), TA1 (262.63), TA4 (258.78), while rmdecreased in the order of TA2 (0.131), TA1 (0.120), TA3 (0.116), TA4 (0.115). In conclusion, the diet with wheat bran as the main ingredient (TA2) proved to be the most suitable for the development, reproduction, and mass rearing of the Oriental fruit fly.
