利用光学显微镜和电子显微镜分析了工蜂幼虫向蛹转化过程中肠上皮细胞死亡的类型。变态开始于幼虫上皮细胞中自噬空泡数量的增加，并终止于整个肠上皮的溶解性破坏。细胞凋亡似乎与细胞年龄无关，但在新器官的形成中起重要作用。甚至在蛹上皮发育的幼虫上皮的再生巢中的细胞中，也发生凋亡性死亡。单个凋亡细胞逐渐从初级多层组织中消失，直到单层蛹上皮形成。一些凋亡细胞被姐妹上皮细胞内吞。
The types of cell death in the midgut epithelium of the worker honey bee during the larva-to-pupa transformation were analyzed by light and electron microscopes. The metamorphosis begins with an increase in the number of autophagic vacuoles in larval epithelial cells and terminates with lytic destruction of the whole intestinal epithelium. Apoptosis seems to be independent of cell age, but important in fashioning of the new organ. Even in the cells in the regenerative nests of the larval epithelium, from which the pupal epithelium develops, apoptotic death occurs. Single apoptotic cells are eliminated gradually from the primary multilayer tissue until the monolayer pupal epithelium is formed. Some of the apoptotic cells are endocytosed by sister epithelial cells.
