“…Under light microscopy, epithelial and glandular cell types can be distinguished in the spermathecae. As observed in spermathecae from other insects, these cells are quite different from each other in terms of morphology and ultrastructure and such differences may be associated with their different roles (Tombes & Roppel 1972, Lay et al 1999, Staccomi & Romani 2010.…”

“…Besides that, in many insects the spermatheca receives and stores secretion from male accessory glands transferred during mating. Unfortunately, most of the data available in literature dealing with the spermatheca are related to systematics, while the ultrastructure of this organ has been studied in only 11 species belonging to the following ive orders: Dyctioptera (Gupta & Smith 1969), Orthoptera (Lay et al 1999), Diptera (Clements & Potter 1967, Filosi & Perotti 1975, Kokwaro et al 1981, Fritz & Turner 2002, Coleoptera (Happ & Happ 1970, Tombes & Roppel 1971, 1972, Villavaso 1975a, and Hymenoptera (Dallai 1975). The structure of this organ is very diversi ied among insects, varying from simple tube to complex organs (Matsuda 1976, Winterton et al 1999, Dallai et al 1996.…”

The spermatheca of Murgantia histrionica (Hahn) was investigated using luorescence, scanning and transmission electron microscopy. The aim of the study was to elucidate the structure of this organ, pointing out differences between mated and unmated females. Results have shown an elaborated cuticular structure associated with muscular and glandular tissues. The spermatheca is joined with the common oviduct by the spermathecal duct, forming a thin saccular dilation through two consecutive invaginations. The distal part of the organ is formed by a series of two communicating cuticular chambers. The irst cylindrical-shaped chamber, corresponding to the coiled region, is wrapped by longitudinal muscular ibers suspended between two cuticular langes. The contractions of these ibers compress a deformable zone of the cylinder, pumping the sperm toward the spermathecal duct. Without contractions the cylinder results to be isolated from the proximal part of the spermatheca by means of a valve. The second chamber, corresponding to the spermatheca, is made of two parts: a truncated-conical sub chamber, with a constant cuticular thickness, bearing on itself the distal lange, where muscular ibers are attached. The second part is a bulb-like structure wrapped in a glandular epithelium. The secretory units are composed by two cells: a secretory cell and an associated duct cell. Every evacuating duct shows a little reservoir just after the terminal apparatus, and converge inside the distal bulb after a tortuous path. The functional implications of this structure in the reproductive biology of M. histrionica are discussed.

“…Apical microvilli in the epithelial cells of the spermatheca have been described in some species of Blattaria [13] , Coleoptera [14,15] , Orthoptera [11] and in the stingless bee Melipona bicolor [16] . In the present study, similar structures, resemble a brush border, were observed in the internal secretory epithelium of A. s. piriventris.…”

The insect's spermatheca store the spermatozoa from the time of copulation until the fertilization of the eggs and consists of a sac, usually associated to glands. The ant species Atta laevigata, Atta sexdens sexdens, Atta sexdens piriventris, Acromyrmex coronatus and Cyphomyrmex muelleri are considered pests, as they cause economics losses to several crops. The spermatheca of these species were examined by scanning electron microscopy, histological and histochemical techniques. Their morphology resembled that of a bilobular pouch partially jointed in the central portion. In A. coronatus and C. muelleri it is flatter in shape than those of other species. The external spermathecal gland, groups of secretory cells, was located at the joining point of the two spermathecal lobes of the reservoir. This was observed in A. laevigata, A. s. sexdens and A. coronatus, like a group of cells, while in C. muelleri, like filaments. An external associated gland was not observed in A. s. piriventris, instead secretory cells were arranged in a simple prismatic epithelium internally lining the spermathecal lumen. This epithelium was also observed in A. s. sexdens, although it was restricted to the joining point of the spermathecal lobes. The presence of an internal secretory epithelium in A. s. piriventris and A. s. sexdens suggests that their physiology for the maintenance of spermatozoa in viable conditions for egg fertilization might differ from A. laevigata, A. coronatus and C. muelleri, in which only an external spermathecal gland was observed.
