“…As eggs pass through the common oviduct they are fertilized by sperm contained within the spermatheca, which is part of an elaborate spermathecal complex. The spermathecal complex in B. hilaris is similar to other pentatomids (Candan et al 2015, Souza et al 2015). It arises from the medial or distal portion of the common oviduct via the spermathecal duct (Figs.…”

In this paper, we describe the morphology of the female Bagrada hilaris (Burmeister) reproductive system and develop a physiological age-grading system related to egg production. The female reproductive system is composed of two meroistic and telotrophic ovaries each containing 5–6 tubular ovarioles. The ovarioles unite into the lateral oviduct which combine to form the common oviduct. The ovarioles are composed of two regions; the distal germarium and the tubular vitellarium which contains maturing follicles. Each follicle is surrounded by a layer of cells; the follicular epithelium. As the follicle passes from the ovariole to the lateral oviducts the follicular epithelial cells slough off and accumulate in the base of the ovarioles and are known as follicular relics. The continuum of ovarian development is divided into two categories: nulliparous (‘nonreproducing’) and parous (‘reproducing’). The nulliparous category is characterized by the absence of follicular relics or eggs in the oviducts as opposed to the parous category where follicular relics and, in many cases, eggs occurred in the oviducts. The nulliparous category is divided further into two stages; N1 and N2 based on ovariole differentiation. The parous category is divided into three stages; P1, P2, and P3, based on the quantity and appearance of follicular relics. Females characterized as P3 produced three times more eggs (79.2 eggs ± 5.7) than females characterized as P1 (27.1 eggs ± 6.0).

“…Spermathecal ducts are region of the sperm transport system, they are responsible for sperm can be transported directly from the spermathecae to the common oviduct (Puchkova, 1959). The two ring sclerites presence within the genital chamber are common to all species of Pentatomidae previously studied (Javahery, 1994;Candan et al, , 2015. Based on our study, morphological characters of eggs and spermathecae of S. coloratum can be useful in the classification of Pentatomidae.…”

“…In some taxa, they are essentially straight; in others they can be very coiled. Also, sometimes there is a swelling or enlargement just below the proximal flange (Javahery, 1994;Candan et al, , 2015. In this SEM study, the distal spermathecal duct and the proximal spermathecal are almost the same length, and muscular structures.…”

The spermathecae and egg morphology of Stenozygum coloratum (Klug, 1845) were examined with light and scanning electron microscopy, and their external morphology was characterized in detail (egg chorion surface, operculum, and aero-micropylar processes, and spermathecae morphology). Eggs are barrel-shaped; operculum is round and the hatching line can be easily distinguished in the scanning electron photograph. The egg batches usually consist of 12 eggs. Because of the thick egg chorion, embrionic development was not visible from the outside. The eggs of S. coloratum are usually laid in two rows and are glued to the Capparis spinosa (Capparacea) plants.The egg burster is highly sclerotized, thick and T shaped. It is clearly observed in the hatched egg. Egg-burster is remains attached with the inside lateral surface of the egg. The well-marked operculum intersects the ring of 18-20 short pipe shaped micropylar projections that are found between the tubercles around the hatching line. In S. coloratum, the spermathecae has a semi-oblong spermathecal bulb, a pumping region, intermediate flanges, a dilation of spermathecal duct and distal and proximal ducts. The pumping region has distal and proximal flanges. The balloon-like median spermathecal dilation has sclerotized rod and is narrowed distally and tipped. The proximal area of the spermathecal duct is close to the vagina opening. Two V-shaped sclerites and two ring sclerites are localized on the genital chamber (vagina) wall in to which opens the spermathecae. Egg and spermathecae structures in insects differ from species to species. In this study, spermateca and egg structures of this species, which have not been studied before, were examined in detail, and it was aimed to contribute to systematic and taxonomic studies.

“…Publications by Kumar (1962, 1965) and McDonald (1966) were the first to indicate the importance of the female genital structures (including spermatheca) for classification and phylogeny in Pentatomoidea. This was confirmed later for most of the pentatomoid families (Servadei 1964; Štys 1964; Štys and Davidová 1979; Davidová-Vilimová and Štys 1980; Schaefer et al 1988; Gapud 1991; Kim and Lee 1993, 1995; Schaefer 1993; Kocorek and Danielczok-Demska 2002; Sweet and Schaefer 2002; Pluot-Sigwalt and Lis 2008; Stacconi and Romani 2011; Candan et al 2015).…”

Structures of spermatheca in 63 species of Scutelleridae (Hemiptera) representing 46 genera and all subfamilies currently recognised in the family were examined and compared. The morphology of three main parts of the spermatheca (receptacle, intermediate part, and spermathecal duct) was described and three main types of spermatheca in Scutelleridae were identified. The taxonomic importance of spermathecal features for the higher classification of scutellerids is discussed.
