Abstract

<b>Background and Objective:</b> The oriental fruit fly <i>Bactrocera dorsalis</i> (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 <i>B. dorsalis</i> 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. <b>Materials and Methods:</b> The attractiveness of the juice and extract/distillate water of the host fruits to <i>B. dorsalis</i> 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. <b>Results:</b> The results show that among the eight fruit juice aromas tested, the ones that significantly affected the number of trapped female <i>B. dorsalis</i> 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 <i>B. dorsalis</i> fruit flies. Two volatile compounds in the banana distillate water were also reported to have the ability to attract female <i>B. dorsalis</i> and other fruit flies. <b>Conclusion:</b> From the results of this study, it can be concluded that the methanol extract and distillate water of the green <i>Ambon lumut</i> banana fruit of <i>Musa acuminata</i> Colla has the potential to be developed as an attractant of female <i>B. dorsalis</i>.
