摘要

本硏究利用胺基甲酸鹽類或除蟲菊類農藥分別依5種比例添加於餌劑中，以評估對瓜實蠅的致死效果。結果顯示，隨著藥劑濃度的升高，瓜實蠅的死亡率也隨著升高。在非選擇性試驗的結果顯示，40%納乃得可濕性粉劑與餌劑1:1000、1:500、1:200或1:100混合以及48.34%丁基加保扶乳劑與餌劑1:200或1:100的混合比其他胺基甲酸鹽類和除蟲菊類農藥對瓜實蠅有較佳的致死效果。另在選擇性測試的結果顯示，40%納乃得可濕性粉劑與餌劑1:100混合與48.34%丁基加保扶乳劑與餌劑1:100混合造成瓜實蠅的死亡率超過80%。而殘效測試的結果顯示，40%納乃得可濕性粉劑與餌劑1:100混合於7天後的死亡率仍可達70%以上。綜合而言，在供試藥劑中，以40%納乃得可濕性粉劑與48.34%丁基加保扶乳劑添加於餌劑內具有防治瓜實蠅的效果，未來可以成爲瓜實蠅整合性管理的治防技術之一。

Studies were conducted to evaluate the mortality of melon fly (Bactrocera cucurbitae Coquillett) on adding carbamates or pyrethroids to baits in five ratios. Higher ratios of insecticides resulted in increased melon fly mortality. In the non-choice test, the mortality resulting from addition of 40% methomyl WP to baits by a ratios of 1:1000, 1:500, 1:200, or 1:100 and 48.34% carbosulfan EC to baits by a ratios of 1:200 or 1:100 were significantly higher than other carbamates and pyrethroids. In the choice test, baits incorporated with 40% methomyl WP in 100:1 or 48.34% carbosulfan EC in the same ratio could also make the mortality higher over 80% for melon fly. In the residual effects, 40% methomyl WP mixing with baits in 1:100 after seven days could make the mortality higher over 70%. It was concluded that the 40% methomyl WP or 48.34% carbosulfan EC adding in baits could manage the population of melon fly effectively. This technique could be applied in the integrated pest management of melon fly.
