“…As for the eggshell itself, the fine detailed structure observed in C. megacephala is comprised of several layers similar to that in Drosophila melanogaster [32]. The characteristic changes in the development of the follicular epithelium (i.e., chorionogenesis) in this blow fly species are even quite similar to those described in the stoneflies Perla marginata and P. pallida (Plecoptera: Perlidae) [33]. The reproductive status of flies may be used to imply approximate generation times or time between egg batches within a population.…”

Abstract-Chrysomya megacephala (F.) (Diptera: Calliphoridae) is a medically important blow fly species in many parts of the world. In this study, we examined the ovary of C. megacephala at the ultrastructural level using light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Dissection of the ovaries revealed eight stages of ovarian development, thus providing a means of estimation of the age of females based on this organ. In the initial stage I (day 0-2), freshly-emerged flies up to three days old each display piriform germaria while the follicles are not yet well differentiated. In stage II (day 3), each follicle is nearly spherical and separating from the germarium. During stage III (day 4), each follicle is now easily distinguished from the germarium and is only connected by a thin interfollicular stalk. The nurse cells are completely surrounded by the cuboidal epithelial follicular cells. In stage IV (day 5-6), each follicle is spherical and considerably enlarged; whereas, the nurse cells within are more differentiated into individual round inclusions and grouped in the follicle chamber. Stage V (day 7) marks appearance of the visible oocyte at the posterior pole of the follicle. During stage VI (day 8), each follicle displays oocyte expansion anteriorly to occupyfrom one-third to one-half of the total length. In stage VII (day 9) the oocyte characteristically fills the posterior two-thirds of the total length of the follicle and in the final stage VIII (day 10), each follicle is completely filled by an oocyte and nurse cells have disappeared. The micropyle and narrow, elongate median area are clearly seen in this final stage. SEM images reveal that the ovary is covered by an ovarian envelope, which is tough and thickened in 3-day-old adult ovarioles; whereas, it becomes thin and fragile in 9-day-old adult ovarioles. TEM analysis of ovarioles of 3-day-old adult flies shows that cuboidal follicular cells containing large nuclei with visible fibrils of muscle simply encircle the large compartments of nurse cells; whereas, ovarioles of 7-day-old adult flies displayed a more completely developed enclosure for the developing oocyte. This was observed by the presence of the outermost follicular cell layer with underlying eggshell, vitelline envelope, trabecular layer, and layer of granular material that surrounded the innermost oocyte.

“…When reaching the anterior pole of oocyte, they begin to form the micropylar apparatus (micropyle), which allows the sperm cells to enter and fertilize the oocyte (Jaglarz et al, 2008). The subpopulations of follicle cells are also investigated in many other insects such as Phthiraptera (Bilinski and Jankowska, 1987), Plecoptera (Rosciszewska, 1995), and Coreidae (Ogorzalek, 2007) and Hydrometridae in Heteroptera (Simiczyjew, 1999).…”

“…As the follicle cells secrete the main components of vitelline membrane, the microvilli carry them to the surface of the oocyte to form the vitelline membrane. In stoneflies, the vitelline membrane is formed by electrondense fibrillar material deposited around microvilli (Rosciszewska, 1995) and the innermost fibrous layer may have water-proofing function (Mouzaki and Margaritis, 1991). In Panorpa, the vitelline membrane might be formed by the compacted protein, the product of the annular rough endoplasmic reticulum.…”

“…The structure of the eggshell has been investigated in many insect orders, such as Lepidoptera (Leclerc and Regier, 1993), Zygentoma (Poprawa and Rost, 2004), Plecoptera (Rosciszewska, 1995), Diptera (Trougakos and , and Hemiptera (Leclerc and Regier, 1993;Ogorzalek, 2007;Poprawa and Rost, 2004;Rosciszewska, 1995;Trougakos and Margaritis, 1998;Vogelgesang and Szklarzewicz, 2001). In Mecoptera, one of the most primitive taxa among Holometabola (Kaltenbach, 1978;Willmann, 1987), the process of choriogenesis and structure of eggshells have been studied only briefly for Panorpodes paradoxa in the species-poor family Panorpodidae (Simiczyjew, 2003).…”

“…Usually, the eggshell may be separated into two major parts: An inner vitelline membrane and an outer chorion. The vitelline membrane, which adheres directly to the surface of the egg (embryo), is usually thin, homogeneous and does not show local modifications, whereas in many insects the chorion consists of several layers and displays regional specialization (Margaritis, 1985;Margaritis and Mazzini, 1998).The structure of the eggshell has been investigated in many insect orders, such as Lepidoptera (Leclerc and Regier, 1993), Zygentoma (Poprawa and Rost, 2004), Plecoptera (Rosciszewska, 1995), Diptera (Trougakos and Margaritis, 1998), and Hemiptera (Leclerc and Regier, 1993;Ogorzalek, 2007;Poprawa and Rost, 2004;Rosciszewska, 1995;Trougakos and Margaritis, 1998;Vogelgesang and Szklarzewicz, 2001).

The morphology and formation of the eggshell in the scorpionfly Panorpa liui Hua were examined with light microscopy and scanning and transmission electron microscopy. During oogenesis of the scorpionfly, the follicle cells multiply by mitotic divisions and diversify into four morphologically distinct subpopulations, three of which are engaged in the eggshell formation and mold various parts of chorion. The eggshell consists of three layers: An inner vitelline membrane, an outer chorion, and a precursor extrachorion. The chorion constitutes a very compact endochorion, a rough fibrillar exochorion, and a polygonal meshwork of elevated ridges. At proximal end of ovarioles the chorion of matured oocyte is covered with a loose membrane, which might be the remnant of follicle cells. The jelly substance, which acts as lubricant to protect the oviducts and ovulated eggs during ovulation, might add to the top of polygonal ridges as the outermost extrachorion after oviposition. The eggshell formation process in Panorpa is tentatively proposed.

The organization of the egg capsule of the euholognathan stonefly, which represents the family Taeniopterygidae (Nemuroidea) was investigated using light and electron microscopy techniques. The presence of a complex, multilayered egg capsule, composed of a vitelline envelope, multilayered chorion, and extrachorion is described. The morphology of the eggshell of Brachyptera risi was compared with that of euholognthan and systellognathan egg coverings and the ground plan of the egg capsule in Plecoptera was discussed.
