Abstract:Although some Chinese scholars have conducted research related to the parasitoid wasp Fopius arisanus (Sonan) and sterile males of the Oriental fruit fly [Bactrocera dorsalis (Hendel)], research related to the integrated control of B.dorsalis using both the parasitoid and sterile males of B.dorsalis has not yet been conducted.Three steps were used to achieve the goal of controlling B.dorsalis using the parasitoid wasp F.arisanus and sterile males of B.dorsalis.First, the size of the male fruit fly population was partially controlled using an attractant to initially reduce the size of the population.Second, the population was further controlled by releasing sterile males of B.dorsalis.Finally, the residual eggs of B.dorsalis in the field were parasitized by releasing F.arisanus.To evaluate the effects of this integrated pest management (IPM) system on controlling B.dorsalis populations, the effects of these three field-based control methods were evaluated by monitoring the population dynamics of B.dorsalis and by investigating the level of fruit damage in the field during the entire IPM process.Specifically, the results of paired-samples T-test were used to evaluate the differences in population dynamics between orchards that received different treatments.The average level of fruit damage and the effectiveness of the control methods were used to evaluate the overall control effectiveness of IPM in the field.The results show, first, that the population of B.dorsalis can be effectively reduced using an attractant.Second, controlling a population of B.dorsalis by releasing the parasitoid wasp F.arisanus and sterile males of B.dorsalis takes a long time and the effects are not immediately obvious.Third, using these two methods together in the field combined with use of an attractant played a significant role in controlling the population of B.dorsalis.Fourth, 90% total control effectiveness can be achieved with these methods.Last, some useful and effective methods for improving control of this pest were also proposed, and drawbacks of the methods used in this study were presented.Based on our results, we suggest successful IPM requires a population of B.dorsalis to first be reduced using an attractant about 1 month before releasing the parasitoid species and sterile males.Next, based on the limitations of this study, some suggestions for further research are presented.First, no uniform standard is available for the concentration or mixing of the attractant suspension in the traps, so this could be analyzed in future.Second, this test was carried out only in a valley, so the effectiveness of this IPM technique should be tested on other terrain.Third, additional testing should be conducted to perfect this IPM.For example, tests using only the parasitoid wasp or only sterile males will be done in future research.Also, future studies could test the effectiveness of releasing different numbers of the parasitoid and/or sterile males at different intervals as a single control measure.Also, studies analyzing and comparing of the economic benefits of different versions of this IPM should be conducted.
