Abstract
瓜實蠅（Bactrocera cucurbitae Coquillett）（雙翅目：果實蠅科）素為瓜類之重要害蟲，可為害幼瓜及成熟果實。2006年在嘉義鹿草苦瓜園以0.02%賜諾殺濃餌劑稀釋8倍，每公尺約點噴5ml處理，試區平均誘到之瓜實蠅雌蟲及雄蟲皆顯著比試區外圍者為少。處理區不套袋苦瓜之平均被害率及被害度分別為19.2%及4.0%，與不施用對照區有顯著差異。在彰化溪州網室內處理前誘到之雌、雄蟲數為9.3及7.3隻，以賜諾殺濃餌劑處理之結果，平均誘到之雌蟲及雄蟲數則分別為0.1及0隻。網室內賜諾殺處理區之不套袋苦瓜平均被害率與被害度，分別僅為0.9及0.1%。另在雲林斗南瓜實蠅發生較多之絲瓜專業區，賜諾殺處理組之絲瓜平均被害度僅為34.7%，而對瓜實蠅之防治率平均幾乎達到50%。綜合上述結果，賜諾殺餌劑對瓜實蠅確具有明顯誘殺效果及應用之潛力。
The melon fly, Bactrocera cucurbitate Coquillett, is the major insect pest of cucumber crops and it is able to damage both young and ripen fruits. Results from a bitter gourd orchard at Lutsao, Chiayi in 2006 showed the average captured female and male melon files from the 0.02% Spinosad-treated plot (8x), were significantly lower than the numbers captured from surrounding area. The average percentage of fruit damage and percentage infestation of non-paper-bagging bitter gourd were only 19.2% and 4%, respectively, in the treated area that were significantly different from the percentage of no bait check. The average number of captured melon files from the Spinosad treated plot in a screenhouse at Hsichou, Changhwa were 0.1 females and 0 male while in the pretest they were 9.3 females and 7.3 males. The average percentage of fruit damage and percent infestation for non-paper-bagging fruits were 0.9% and 0.1%, respectively, in the screenhouse. In addition, the averaged percent infestation was only 34.7% from the Spinosed-treated plot in a special sponge gourd producting area with high melon fly population at Tounan, Yunlin and the averaged control rate was up to 50% for the melon fly. In conclusion, the Spinosad bait exhibit a significant control to the melon fly and is of great potential in its application.
