Morphology of the Antennal Sensilla of the Oriental Fruit Fly, Dacus Dorsalis Hendel (Diptera: Tephritidae)

東方果實蠅(Dacus dorsalis Hendel)觸角感覺毛形態之研究

摘要


利用掃描電子顯微鏡技術研究東方果實蠅Dacus dorsalis觸角感覺毛外部形態。東方果實蠅之觸角結構,雌蠅與雄蠅相同,包括有柄節(Scape),梗節(Pedicel)和鞭節(Funiculus)三部份。柄節和模節上著生有豐富的細毛(Microtrichia)和剛毛(Chaetae)。鞭節上具有七種不同型態之感覺毛(Sensilla)遮覆於細毛下方,這七種感覺毛可歸屬4類,它們是毛狀感覺毛(Trichoid Sensilla)I型和II型,棒狀感覺毛(Clavate Sensilla)I型和II型,突出感覺毛(Basiconic Sensilla)I型和II型,以及時針感覺毛(Styloconic Sensilla)。這些感覺毛之外部形態特徵及其在鞭節上著生好佈情形和數目,均詳細研究觀察並報告於原文。

並列摘要


The external antennal sensilla morphology of the oriental fruit fly, Dacus dorsalis Hendel has been studied with scanning electron microscopy. The antennae of this fly, exhibiting no sexual dimorphism, consists of 3 segments: basal scape, pedicel, and elongated funiculus. The scape and the pedicel have dense microtrichia and chaetae. Seven distinct morphological types of sensilla belong to 4 groups on the funiculus, among the microtrichia. These sensilla are: trichoid sensilla types I and II, clavate sensilla types I and II, basiconlc sensilla types I and II, and styloconic sensilla. The morphological characteristics, distribution, and quantity of each sensillum on the funiculus are described below.
