中文摘要 | 荔枝細蛾(Conopomorpha sinensis Bradley)為荔枝果實生長發育過程中危害最甚的害蟲之一,生產者通常藉由施灑化學殺蟲劑以快速、有效地控制該害蟲。套袋是另一個選擇方案,可藉此提供友善環境與安全果品。荔枝品種「台農1號」因其穩定高產,深具發展為減藥生產品種潛力。結合該品種與適當的套袋處理,可作為安全荔枝生產的解方之一。本研究著重於「台農1號」荔枝套網袋生產的2項重要議題,包含套袋時機及所用網目大小對防治荔枝細蛾入侵的效果。研究中據此以套袋的時機及套袋材質孔徑兩項作為探討因子,並藉由追蹤落果表現、果實品質及危害情形來評估套果效益。研究結果顯示,在偏雌花盛開後3 wk套袋,可使生殖生長枝收穫最多且果實不受蟲害;未套袋的荔枝果實受害率則達到97.5%,且單果重量減少26.9%,可溶性固形物含量亦低於17°Brix。另外,使用16網目,並無法全然防範荔枝細蛾對果實的危害。因此,建議使用更細緻的網目,作為防範荔枝細蛾危害的套袋材料。 |
英文摘要 | Litchi fruit borer (Conopomorpha sinensis Bradley) is the most important pest during the fruit growth and development in litchi. Generally growers use chemical pesticides to control pest efficiently. Bagging is an alternative method, providing suitable growing environment and safe fruit. The litchi variety 'Tainung No. 1' may have potential to develop into a low pesticide used variety due to its stable and high yield traits. A combination of suitable variety and bagging practices could be the resolution for production of safe litchi. This study considered two important approaches, timing and mesh size of net, for the experiment. Best fruit bearing without pest infestation was observed on panicles which had bagged at 3 wk after full female bloom. About 97.5% fruit from unbagged panicles were infested by litchi fruit borer, with 26.9% fruit weight loss and reduction of total soluble solids content (less than 17°Brix). In summary, 16-mesh net cannot absolutely protect fruit from damage by litchi fruit borers. It is recommended to use the more fine materials. |
