摘要

柑桔類作物為臺東縣東河鄉泰源幽谷的重要產業，栽培面積約400公頃，長期受東方果實蠅（Bactrocera dorsalis（Hendel））的威脅，影響果實品質與產量。為有效防治東方果實蠅，臺東區農業改良場於2010年在東河鄉泰源幽谷進行東方果實蠅區域共同防治試驗，與東河鄉農會合作，整合泰源幽谷柑桔及柚子產銷班共計14個產銷班，參與防治工作。工作內容透過密度監測，配合滅雄、滅雌等技術，並落實田間清潔等措施進行。試驗期間自2010年1月起至2011年3月產季結束，除果實蠅共同防治剛推行時1月高峰平均8.8隻／陷阱／天，至採收期降至3.3隻／陷阱／天；重新設置監測點後，至10月高峰期果實蠅密度平均7.2隻／陷阱／天，其後持續維持低密度狀態。田間晚崙西亞橙果實受害率調查結果顯示，未套袋果實平均受害率8.43%。

About 400 ha. of citrus were grown at Taiyuan valley, Donghe Township, in Taitung, it wa an important crop for local economy, however, the threat from the oriental fruit fly(Bactrocera dorsalis (Hendel)) is a constant problem. To effectively control the oriental fruit fly, Taitung District Agricultural Improvement Station promoted the area-wide control of the oriental fruit fly in 2010 in Taiyuan valley, Donghe Township. With the corporation of growers from Donghe Township, an area-wide oriental fruit fly control program was launched in 2010. Measures included geographic and agricultural information gathering, oriental fruit fly population monitoring, male annihilation by methyl eugenol bait and protein food bait to kill and lure female oriental fruit fly were implemented. In this study, 8.8 fruit flies / trap / day was detected at the beginning of the control program on January 2010, but the population density of fruit fly decreased thereafter, and was dropped to 3.3 / trap / day by harvest on March 2011 ; the highest peak was 7.2 fruit flies / trap / day in October, then continue to maintain a low-density status. By sampling the Valencia from three orchards, 8.43% damage rate was obtained.
