This means that the Queen has the ability to hold more and produce more eggs at one time. Physogastric Queens produce an enormous amount eggs which can account for a significant amount of their body weight. Specifically in ''Macrotermes subhyalinus,'' eggs can actually make up 1/3 of their body weight as a 15 g Queen can make up to 30 eggs/min. The Physogastric Queens' egg production is supported by oocyte proteins supplied by the "queen body fat." == Physogastrism in Termite Species == Physogastrism in termites presents itself in quite an unusual manner. Unlike most physogastric insects, the queen termite is able to increase its size without the use of cuticular molting. Rather, the queen unfolds and stretches her abdominal epicuticle in order to make room for the subsequent egg deposits. This process has been observed to be incredibly slow (sometimes over the course of several years). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Physogastrism」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
