Abstract：
Insect metamorphosis involves significant changes in insect internal structure and is thus a critical focus of entomological research. Investigating the morphological transformation of internal structures is vital to understanding the origins of adult insect organs. Beetles are among the most species-rich groups in insects, but the development and transformation of their internal organs have yet to be systematically documented. In this study, we have acquired a comprehensive dataset that includes 27 detailed whole-body tomographic image sets of Harmonia axyridis, spanning from the prepupal to the pupal stages. Utilizing this data, we have created intricate 3D models of key internal organs, encompassing the brain, ventral nerve cord, digestive and excretion systems, as well as the body wall muscles. These data documented the transformation process of these critical organs and correlations between the origin of adult and larval organs and can be used to enhance the understanding of holometabolous adult organ genesis and offers a valuable reference model for investigating complete metamorphosis in insects.
摘要：
昆虫变态涉及昆虫内部结构的重大变化，因此是昆虫学研究的重点。研究内部结构的形态转变对于了解成年昆虫器官的起源至关重要。甲虫是昆虫中物种最丰富的群体之一，但是他们内部器官的发展和转变尚未得到系统的记录。在这项研究中,我们已经获得了一个全面的数据集，其中包括27个完整的Harmoniaaxyridis全身断层图像集，从pupal到p阶段。利用这些数据，我们创造了复杂的关键内脏器官的3D模型，包围大脑，腹侧神经索，消化系统和排泄系统，以及体壁肌肉。这些数据记录了这些关键器官的转化过程以及成虫和幼虫器官起源之间的相关性，可用于增强对全代谢成虫器官起源的理解，并为研究昆虫的完全变态提供了有价值的参考模型。
