基本含義
pupal是英語形容詞(adj.),意為“of, relating to, or characteristic of a pupa”,即與蛹相關的或具有蛹的特徵,中文可譯為“蛹的”或“處於蛹階段的”。
其英式與美式發音均為['pjuːpəl]。
該詞常用於描述昆蟲的發育階段,如“pupal stage”(蛹期)、“pupal cases”(蛹殼)等表達。
與“larval”(幼蟲的)相比,pupal特指昆蟲發育的蛹階段。
基本特徵
pupal是一個形容詞(adj.),意為“蛹的”,用於描述與蛹相關的事物。其音標為英['pju:pəl],美['pjupəl]。例如“the pupal stage of development”(蛹的發育階段)。相關詞為larval。

在家蠶(Bombyx mori)的
變態發育過程中,同源域轉錄因子(如BmPOUM2和ABmAbd-A)被證實調控著蛹期基因(pupal genes)的轉錄。這些基因的表達受蛻皮激素調控,並在蛹期表現出異性專一的表達模式。相關研究為深入理解昆蟲變態發育的激素調控機制提供了新視野,也為培育長蛹期家蠶品種、提高蠶絲品質提供了理論基礎。

雙語例句
Peridomestic and intradomestic areas were much more important for pupal production than commercial and public spaces other than schools and religious facilities.人類住所周圍和內部區域對於蛹的繁殖較商業和公共場所(除了學校和宗教場所以外)要重要得多。
And here’s something scary: The Berkeley scientists can now implant the MEMS equipment during the pupal stage so that the beetles emerge embedded with electrodes, ready to be wired up.有一點很可怕:伯克利分校的科學家目前已經能夠在昆蟲還處於蛹的階段就將微機電系統(MEMS)設備植入昆蟲體內,所以昆蟲內嵌著電極長大,並且準備好了接通電源。
A complex but non-significant association was found between water supply and pupal counts, and lack of waste disposal services was associated with higher vector abundance in only one site.我們發現,水的供應和蛹的數量之間存在複雜但非重大的關聯,沒有水處理設施只在一個地點與較高的病媒豐度存在關聯。
