Oogenesis and spermatogenesis are two fundamental processes of gamete formation in insects, essential for sexual reproduction. Both processes involve a series of cellular divisions and differentiation steps that transform germ cells into mature eggs and sperm, respectively. Oogenesis in insects begins with the differentiation of oogonia, which are diploid germ cells located in the ovaries. These oogonia undergo several mitotic divisions to increase their number before entering the first meiotic division, becoming primary oocytes. The primary oocyte then undergoes meiosis I, but this process is often arrested at prophase I until certain developmental signals trigger its continuation. After completing meiosis I, the cell divides into a secondary oocyte and a smaller polar body, which generally degenerates. The secondary oocyte proceeds to meiosis II but usually pauses at metaphase II until fertilization occurs. During oogenesis, a significant amount of cytoplasmic growth and yolk deposition takes place. The oocyte accumulates nutrients and yolk proteins, which are synthesized in the fat body and transported via hemolymph. These yolk proteins are taken up
