馬拉巴栗 (Pachira macrocarpa Walp) 葉片氣味對東方果實蠅 (Bactrocera dorsalis) 及瓜實蠅 (B. cucurbitae) 之誘引探討

Abstract

本試驗證實馬拉巴栗 (Pachira macrocarpa Walp) 葉片之氣味俱有誘引東方果實蠅 (Bactrocera dorsalis)及瓜實蠅 (B. cucurbitae) 之效果，亦可誘使東方果實蠅雌蟲在內置有碎葉片之黃色塑膠球內產卵，但不會誘引瓜實蠅雌蟲產卵。初步試驗證實此葉片中所含的成分可同時誘引東方果實蠅及瓜實蠅，具有開發成為誘引劑之潛力，惟仍需進一步萃取、鑑定和評估。 The leaf odor of the Malabar chestnut (Pachira macrocarpa Walp ) was proven to be attractive to the Oriental fruit fly (Bactrocera dorsalis) and the melon fly (B. cucurbitae ). It can also attract female Oriental fruit flies but not female melon flies to lay eggs in yellow plastic balls. The results of this experiment showed that the chemical compounds existing in the leaf may have great potential for development as attractants for both fruit fly species. However, further extraction, identification, and evaluation of individual compounds are needed in future studies.
