Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Female reproductive system of Varroa jacobsoni is laelaptide-shaped and consists of U-shaped ovary with main partvitellarium, short oviduct, uterus and vagina which opens by genital orifice. Receptaculum seminis is connected via tubuli anulati and rami sacculi with sperm induction pores and, directly, with uterus. Differentiated accesory glands are absent. In receptaculum seminis, prospermia develop into spermatozoa. Weakly stainabe pyriform cells of receptaculum seminis are located mostly at the wall, separating it from the ovary. In adult inseminated females, receptaculum seminis is displaced laterally by developing Ovary, and clearance of tubuli anulati and rami sacculi of the receptaculum close, so that they became thin, weakly recognizible filaments. Ogenesis of nutrimentary type, with no folliculi formation. Oocyte nutrition is of teleotrophic type. Generative organs develop from unpaired profetal rudiments of a protonymph. Oocyte formation takes place only in females not started to lay eggs. Oocyte number per female reaches 25. Insemination is resulted probably in spermatozoa penetration through mellow wall between receptaculum seminis and ovary main part. Age changes in the uteral epitelium are described. It is shown that reproductive capacity of a female is limited by eco-physiological conditions of the first, probably singular, oviposition, age reduction changes of the uteral epithelium and singular copulation due to destructive changes in receptaculum seminis after insemination. |
