Fitness of Bactrocera dorsalis (Hendel) on seven host plants and an artificial diet
Turkish Journal of Entomology 38 (4), 401-414
Abstract: The oriental fruit fly, Bactrocera dorsalis (Hendel), is one of the most destructive pests in the Asia and Pacific area and is an important quarantine pest for the United States and many countries. This fly attacks more than 150 cultivated and wild fruits in Taiwan. To build an ecological database, we studied the life tables of B. dorsalis reared on seven host plants and an artificial diet at 25±1°C, 70±10% R.H., and a photoperiod of 12:12 (L:D) h. The life history raw data were analyzed using an age-stage, two-sex life table. The mean fecundity (F) ranged from 252.3 to 1300.3 eggs per female, and the highest fecundity was observed on pomelo; the net reproductive rate (R0) ranged from 100.9 to 588.3, and the highest reproductive rate was observed on jujube. The intrinsic rate of increase (r) was 0.1790, 0.1667, 0.1333, 0.1261, 0.1161, 0.1128, 0.1120, and 0.0797d-1on pitaya, artificial diet, guava, sweet orange, wax apple, pomelo, jujube, and wild-type mango in descending order, respectively. The high fecundity, net reproductive rates, and intrinsic rates of increase on these common fruits explain not only the high fitness of B. dorsalis as a pest in many areas but also the difficulty in managing this pest in past decades, as well. Finally, the results of a population projection could reveal the population growth and stage structure. The study were demonstrated that the age-stage, two-sex life table is a promising and reliable tool for pest management and general ecological study.
