| 中文摘要 | 龍骨瓣莕菜 (Nymphoides hydrophylla) 俗稱水蓮或野蓮,為生長於水塘中之水生 作物,統計資料顯示在高雄美濃地區栽種面積已超過 180 公頃。然近年發現褐帶紋水 螟 (Parapoynx crisonalis) 會取食其葉片並造巢形成危害。為防治此害蟲,本研究先 於室內篩選可防治此蟲之蘇力菌 (Bacillus thuringiensis) 產品,結果顯示庫斯蘇力菌 產品於測試 120 h 後,褐帶紋水螟幼蟲死亡率最佳者可達 100%。結合無人機 (UAV) 進行蘇力菌的田間藥效試驗,無人機施藥參數測試結果顯示每公頃 40 L 的水量,其 有效噴幅可達 2.73±0.92 m;於龍骨瓣莕菜栽種後期,以飛行速度 2.6 m/s 與有效噴幅 2.7 m 等基本施藥參數下,以無人機噴施蘇力菌確認褐帶紋水螟之田間防治成效,結 果顯示蘇力菌處理組可有效降低褐帶紋水螟之造巢率,並減少龍骨瓣莕菜葉片受危 害之情形,本篇研究是第一篇應用無人機於龍骨瓣莕菜蟲害防治之研究,未來應有 助於作為龍骨瓣莕菜蟲害防治工作之基礎。 |
| 英文摘要 | Nymphoides hydrophylla, commonly known as anemone, water skin lotus, or crested floating-heart, is an aquatic crop of Taiwan that is grown in ponds. Statistical data indicates that the total area of cultivated anemone in the Meinong region of Kaohsiung currently exceeds 180 hectares. In recent years, an insect pest was identified as Parapoynx crisonalis on anemone leaves. P. crisonalis is capable of damaging crops by feeding and nesting. The current study screened Bacillus thuringiensis (Bt) products to determine their efficacy against P. crisonalis. Our laboratory results showed that Bt products based on B. thuringiensis subsp. kurstaki (Btk) achieved 100% larval mortality within 120 hours of feeding. And then, we conducted field efficacy trials, using unmanned aerial vehicles (UAVs) to apply Bt products. UAV application parameter tests revealed that the effective spray width was 2.73 ± 0.92 meters, and water volume was 40 L per hectare. During later anemone growth stages, field efficacy trials with UAV were carried out at a flight speed of 2.6 m/s and a spray width of 2.7 meters. Results confirmed the field efficacy of UAVsprayed Bt against P. crisonalis, with Bt treatments significantly reducing the nesting rate of P. chrisonalis and the leaf damage to anemones. This study is the first study on the application of UAVs in the insect pest control of anemone crops. Findings from this study should benefit pest control efforts in anemone crops in the future. |
