摘要

本試驗設計長效型果實蠅誘殺器，改善高屏地區防治東方果實蠅（Bactrocera dorsalis Hendel）之適用性，分別在綜合果園區（高雄場）、番石榴園（高雄縣燕巢鄉）及芒果園（屏東縣枋山鄉）三個不同果樹種植區進行田間誘殺試驗，以中改式誘殺器（目前田間監測果實蠅棲群密度用）配合含毒甲基丁香油誘殺板作對照，在綜合果園區及番石榴園之試驗結果顯示，長效型誘殺器在誘殺蟲數及含毒甲基丁香油之使用量與對照組間均有顯著差異，誘殺蟲數分別可達1.46倍（綜合果園區）及2.08倍（番石榴園），而含毒甲基丁香油之使用量則分別節省27.7%及20.3%。長效型誘殺裝置除了節省含毒甲基丁香油之使用量，更提升了持續誘殺果實蠅效能，且在試驗過程中連續四個月無需更換誘殺藥劑，在果實蠅高密度區可達到更方便且更有效率防治成效。

This study was to design a trap with longer efficiency to improve the effectiveness of the traps currently used for the control of the oriental fruit fly, Bactrocera dorsalis Hendel, in the Kao-Ping area. Field tests of the effectiveness of the traps were conducted in three different orchards: a combination-fruits orchard at the Kaohsiung District Agricultural Research and Extension Station, a guava orchard at Yen-Chao Hsiang, Kaohsiung County, and a mango orchard at Fan-Shan Hsiang, Pingtung County. A modified trap, commonly used for monitoring population densities of the oriental fruit fly, in combination with methyl eugenol impregnated fiber boards, was chosen as the control. The results showed that the average number of the fruit fly adults caught in the combination-fruits orchard and the guava orchard using the longer efficiency trap was significantly higher by 1.46 and 2.08 times, respectively, than the control. The volume of methyl eugenol laced with naled used in the longer efficiency traps, which were placed in the combination-fruits orchard and the guava orchard, was significantly reduced at 27.7% and 20.3%, respectively, as compared with that used in the control. The longer efficiency trap not only reduced the volume of methyl eugenol laced with naled used, but also prolonged the effectiveness of trapping the fruit fly. It was also demonstrated that no replacement of the methyl eugenol used in the longer efficiency trap was necessary in four months. This would greatly enhance the effectiveness of the fruit fly control in high population density areas.
