“…These results are corroborated in the grasshopper Gomphocerus rufus, where proteolitic enzymes secreted from epithelial gland cells into the spermathecal lumen digest the transferred spermatophore (Hartmann, 1970). The actual process of dissolution and resorption was demonstrated in the grasshopper Chorthippus curtipennis by ligaturing a spermathecal duct that contained a transferred spermatophore (Hartmann and Loher, 1974).…”

The white secretions (WS) from the tubules of the male accessory glands (AG) of Locusta migratoria are composed of peptides and proteins. The WS are transferred during mating to the female's spermatheca. They have been followed to their destinations with immunological and radioactive marker techniques. In the spermatheca, peptides are split off from WS-protein complexes, permeate the spermathecal epithelium via glandular cells, enter the hemolymph and attach to other proteins in various target organs such as the dorsal fat body, the preterminal/terminal oocytes, and the follicular cells. In developing eggs, they concentrate at the posterior pole where sperm enters the egg, and in early embryogenesis they are found in the germ band. These results extend the functions of the spermatheca and the role of the male during the reproductive process.

“…A similar complexity with regards to the external shape could be demonstrated for the accessory glands of G. bimaculatus , whereas the respective organs of G. assimilis and T. commodus have a much simpler structure (Sturm 2002a, 2002b, 2008; Sturm and Pohlhammer 2000). Concerning the external gland shape of A. domesticus , a certain analogy between females and males may be attested, insofar as the male accessory organs are also marked by an increased complexity of their external structure with respect to other orthopteran species (Hartmann 1970). …”

The accessory glands in the genital tract of female Acheta domesticus L. (Orthoptera: Gryllidae) were investigated in detail. The glands are situated within the 7th and 8th abdominal segment and lead to the genital chamber lateral to the terminal papilla of the ductus receptaculi. The shape of the gland is characterized by a complex system of tubules, including numerous ramifications. The gland's size ranges from 2 to 4 mm. The epithelium is constructed according to a simple scheme and consists of a cuticular intima at the luminal side, one layer of gland cells, and a basallamina at the outermost side. The observed morphology of the accessory glands widely corresponds with that in other cricket species (e.g., Teleogryllus commodus). This is also true for the structure of a single gland cell, which can be subdivided into a basal part with nucleus and intracellular cisternae, as well as an apical part with all those compartments responsible for the production of the secretion. The secretion itself may be classified as lipophilic and is produced for the first time 4 to 6 days after the imaginai moult. Several endogenic functions of the secretion are discussed (lubricant for oviposition, support for introducing the tube of the spermatophore into the ductus receptaculi, etc.).

“…(Boldyrev 1929), Camnula pellucida, Chortoicetes terminifera, and Locustana pardalina (Pickford, unpub. data)] and the Gomphocerinae [including Gomphocerus rufus (Hartmann 1970) and Euthystira brachyptera (Renner 1952)l all form only a single spermatophore during copulation. Thus, within the Acrididae, there appears to be a close physiological relationship between the Cyrtacanthacridinae and the Catantopinae, and between the Oedipodinae and the Gomphocerinae.…”

SPERMATOPHORE FORMATION AND SPERM TRANSFER IN THE DESERT LOCUST, SCHISTOCERCA GREGARIA (ORTHOPTERA: ACRIDIDAE)

Can. Ent. 105: 613-618 (1973) Sperm transfer in the desert locust, Schistocerca gregaria (Forsk.), is accomplished by means of small (1.5 mm) spermatophores, formation of the first of which begins almost immediately after coupling. A normal copulation, which lasts 4 hours or longer, results in the production of about 6 spermatophores and a maximum of at least 14. Some details of the process of spermatophore formation are presented and differences among certain groups of acridoids are discussed.
