The insect fat body is the main organ of the intermediate metabolism of insects. The majority of proteins of the haemolymph is synthesized in this tissue, which also presents the functions of lipids, carbohydrates and proteins storage. This tissue is also responsible for the synthesis of vitellogenins, proteins with an important role in the reproduction of the insects, being incorporated into the oocytes during vitellogenesis. The fat body consists of thin layers or strings, generally one or two cells thick, or small nodules suspended in the hemocele through connective tissues and trachea. Within a species, the structure of this tissue is more or less constant, but can have considerable differences between insects of different orders. In this way, this article makes a review about the main morpho-physiological features of the fat body cells of the insects, as well as a phylogenetic study of the fat body between basal and derived species of the Attini tribe ants.
昆虫的血体腔是昆虫中间代谢的主要器官。血液中的大多数蛋白质都是在这个组织中合成的，它还具有储存脂质、碳水化合物和蛋白质的功能。这个组织还负责卵黄蛋白原的合成，卵黄蛋白原是一种在昆虫繁殖中起重要作用的蛋白质，在卵黄生成过程中被纳入卵母细胞。血体腔由薄的层或线组成，通常为一层或两层细胞厚，或通过结缔组织和气管悬浮在血腔中的小结节。在一个物种中，这种组织的结构或多或少是恒定的，但在不同目昆虫之间可能存在相当大的差异。本文对昆虫血体腔细胞的主要形态生理特征进行了综述，并对 Attini 蚁科中基础和衍生物种的血体腔进行了系统发育研究。
