本研究於實驗室進行家蠅取食偏好及顏色偏好的試驗，並於田間進行食物誘引劑對家蠅的防治效果。嗅覺測定設備顯示家蠅對牛肉蛋白及台糖貳號特砂糖有較佳的嗅覺偏好。以網籠進行家蠅取食偏好，家蠅對台糖貳號特砂糖調配蔗糖溶液的取食偏好高於黑糖蜜、台糖高級紅糖及台糖精製特砂，對 50% 蔗糖溶液有較高的取食偏好。利用50% 蔗糖溶液調製不同濃度的介面活性劑，結果發現添加介面活性劑不會降低家蠅的取食偏好，與50% 蔗糖溶液的取食結果無顯著差異。家蠅對 10% 牛肉蛋白的取食偏好明顯大於雞肉蛋白及幼鰻粉，家蠅對10% 牛肉蛋白溶液有較強的取食偏好。本實驗証實家蠅對 50% 蔗糖溶液混合 5% 牛肉蛋白與 5% 幼鰻粉混合溶液的取食偏好明顯大於其他供試溶液。加入乙醇可增加食物誘引劑的誘引效果。食物誘引劑配製後第0至第2天對家蠅有較佳的誘引效果。顏色會影響對家蠅的誘引效果，以塗刷白色誘引器的誘引效果最佳，與顏色蠅格子進行家蠅對顏色偏好的結果一致，塗刷白色的誘引器須添加食物誘引劑才會增加對家蠅的誘引效果。於養雞場進行食物誘引劑與誘引器顏色對家蠅防治效果評估，以蠅格子估算家蠅發生數量，計算第3天、第 4天、第 5天、第 6天、第 7天及第 8天計算家蠅的防治率分別為 77.08、 85.53、84.67、91.20%、94.48及95.86%，試驗進行第4天及第8天後，誘引器內平均誘引家蠅數量分別為1200及1335隻，可有效降低家蠅發生數量。本研究以無毒安全的食物誘引劑，配合誘引器顏色，可有效防治田間家蠅數量，更可提供未來開發家蠅餌劑的參考。 The food preference and color preference of the house fly were investigated in the laboratory and field. Several different carbohydrates and proteins were tested in liquid formulations. Multiple choice assays were performed on house fly to evaluate specific food preferences. The olfactometers were observed that the housefly preferred TSC NO. II sugar and beef peptone powder significantly. The significantly preferred TSC NO. II sugar compared with dark molasses, brown sugar and white sugar solution at a concentration of 40%. The significant preference concentration of sucrose solution is 50%. Three series of Tween 20 solution concentration were prepared using a 50% sucrose solution compared trapping rate that seemed to no affect the food preferences of the house fly. The results indicated a significant preference for beef peptone solution at a concentration of 10% compared with chicken peptone and elvers powder and the most significant preferences for house fly was the mixture of beef peptone and elvers powder. The best mix ratio of beef peptone and elvers powder was 5:5 with 50% sucrose solution. Three series of ethanol solution concentration were prepared using a 50% sucrose solution with 5% beef peptone and 5% elvers powder compared trapping rate. The trapping rate seemed to increase affect the food preferences of the house fly. The trapping rates of food lures prepared in 0-2 days were significant higher than in 3days fermented commercially available fish meal. The housefly preferred white fly trap was the same result as using colors fly counting grill for house fly. The white house fly trap with food lures and water, respectively, for the housefly preference test, showed food lures will be added to increase the attractant effect of housefly. The field trials results the control rate average of 77.08-95.86%. The findings may provide more enticing attractant bait in the future to development more strength and efficiency food lures and color trapping device.
