“…It is possible that Acps could participate in other phenomena we observed, such as potentially contributing to the clear liquid in the anterior uterus in Stages 4-10, or in inducing the synthesis or secretion of this fluid (for example, by the parovaria (in Drosophila: Nonidez, 1920; antibacterial activity in Ceratitis capitata, Marchini et al, 1993), spermathecae or spermathecal glands (in Drosophila and Rhodnius prolixus: e.g. Anderson, 1945;Davey and Webster, 1967;Filosi and Perotti, 1975), or uterine lining (in Drosophila: Middleton et al, 2006)). However, available strains, reagents and methods for Drosophila do not allow us to test this possibility.…”

In most insects, sperm transferred by the male to the female during mating are stored within the female reproductive tract for subsequent use in fertilization. In Drosophila melanogaster, male accessory gland proteins (Acps) within the seminal fluid are required for efficient transfer and subsequent accumulation of sperm in the female's sperm storage organs. To determine the events within the female reproductive tract that occur during sperm storage, and the role that Acps and sperm play in these events, we identified morphological changes that take place during sperm storage in females mated to wild-type, Acp-deficient or sperm-deficient males. A reproducible set of morphological changes occurs in a wild-type mating. These were categorized into 10 stereotypic stages. Sperm are not needed for progression through these stages in females, but receipt of Acps is essential for progression beyond the first few stages of morphological changes. Furthermore, females that received small quantities of Acps reached slightly later stages than females that received no Acps. Our results suggest that timely morphological changes in the female reproductive tract, possibly muscular in nature, may be needed for successful sperm storage, and that Acps from the male are needed in order for these changes to occur.

“…The spermathecal gland secretion of insects is involved in spermatozoa activation, spermatozoa transfer to the spermatheca, and maintenance of spermatozoa (Davey & Webster 1967;Bhatnager & Musgrave 1971;Villavaso 1975;Grodner & Steffens 1978). In L .…”

Functional anatomy of the reproductive system ofListronotus bonariensis(Kuschel)

The reproductive anatomy and development of adult Listronotw bonariensis is described, illustrated and discussed in relation to other Coleoptera. The ovaries of the female are teletrophic and are characterised, during the vitellogenic stages, by lack of nutritive cords and interfollicular tissue. Oocyte resorption is indicated by crystalline inclusions in the pedicels. Mature eggs are stored in the calyx, a structure contiguous with the median oviduct and characterised by a spinose intima. Distinctive features of the male reproductive system are the paired seminal vesicles, accessory glands and prostate glands. Sperm stored in the seminal vesicles is mixed with secretions of the accessory and prostate glands before transfer to the female in the form of a spermatophore during mating. Weevils mate repeatedly. The spermatophore is dissolved in the bursa copulatrix and the sperm are stored in the spermatheca.

“…The endocrinal implications of this were discussed by Davey in 196ôband he has since shown that active secretion does take place after mating in Rhodnius (Davey and Webster, 1967).…”
