渦旋式誘蠅器對東方果實蠅（雙翅目：果實蠅科）之誘殺效果

田間測試結果，利用含毒或不含毒甲基丁香油誘殺板之渦旋式誘蠅器對東方果實蠅(Bactrocera dorsalis (Hendel))皆有良好的誘殺效果，可持效8個月以上，經再次試驗之結果亦同。雄蟲誘殺量可隨誘蠅器內誘殺板甲基丁香油含量之增加而增加，每片吸滿12ml以上時可發揮最大功效。室外陽台觀察結果，在4個月內亦以不含毒閉密式之渦旋式誘蠅器具有較佳之持續誘殺效果。連續8天及6天短期觀察結果，含毒、密閉與否之誘引力差異不明顯，縱然是使用含毒之誘殺板，亦宜置於渦旋式誘蠅器內。進一步田間蓮霧園測試結果，含毒誘殺板之誘殺雄蟲量，僅為不含毒誘蠅器誘蟲數之44.4%。在荔枝園渦旋式誘蠅器不論使用含毒或不含毒之甲基丁香油，再添加蜂蜜或尿素並不會增加誘殺效果。在含毒或不含毒誘蠅器外加覆粘蟲紙，亦不會明顯增大誘殺效果。另外，在渦旋式誘蠅器之底邊周圍打5個小孔，並不會影響其誘引力，確可解決器內積水問題。

The results of field tests showed that it was effective in attracting the Oriental fruit fly, Bactrocera dorsalis (Hendel), by using the Victor fly trap in which a poisoned or non-poisoned methyl eugenol (ME) fiber board was placed. Its effectiveness could last for more than eight months, which was further proven in the subsequent test. The number of male trapped was greatly increased with the increase of the concentration of ME in Victor fly trap. The amount of ME more than 12ml per fiber board produced the best result in attracting male. Observations also showed that the non-poisoned ME in the closed Victor fly trap had the best lasting effects in attracting males within a period of four months. There was no significant difference between poisoned and non-poisoned ME traps in a continuous short-term observation for 6 and 8 days. An additional test in wax apple orchard showed that the number of male trapped by poisoned ME in Victor fly trap was only 44.4% as compared with that of non-poisoned ME. In litchi orchard, adding honey or urea to poisoned or non-poisoned ME did not influence the effectiveness of attracting the Oriental fruit fly. Similar results were also observed in adding sticky board to poisoned or non-poisoned Victor fly trap. Piercing 5 small holes at the bottom of the Victor fly trap did not affect the effectiveness of the trap, and could prevented the problem of water accumulation in the trap.
