Background and Objective: The oriental fruit fly Bactrocera dorsalis (Hendel) is one of the most important insect pest species of fruit and vegetable crops in the tropical and subtropical regions. This study aimed to determine the attraction of female and male B. dorsalis fruit flies to the aroma of fruit juice from the host plants as well as their attraction to methanol extract, ethyl acetate extract and distillate water of selected host fruits. Materials and Methods: The attractiveness of the juice and extract/distillate water of the host fruits to B. dorsalis fruit flies was carried out in an experimental cage measuring 200×200×200 cm that was placed in the laboratory. The volatile compounds in the juice, methanol extract, ethyl acetate extract and distillate water of the selected fruits were analyzed using GCMS-Pyrolysis. Results: The results show that among the eight fruit juice aromas tested, the ones that significantly affected the number of trapped female B. dorsalis were the aromas of banana juice, papaya juice and chilli juice. The results of the analysis by GCMS-Pyrolysis showed that the methanol extract of banana fruit contains one volatile compound that was previously reported to have the ability to attract female B. dorsalis fruit flies. Two volatile compounds in the banana distillate water were also reported to have the ability to attract female B. dorsalis and other fruit flies. Conclusion: From the results of this study, it can be concluded that the methanol extract and distillate water of the green Ambon lumut banana fruit of Musa acuminata Colla has the potential to be developed as an attractant of female B. dorsalis.
