摘要

In this study, the female reproductive system of Isotomus speciosus (Cerambycidae) and Mylabris cernyi (Meloidae) species were examined anatomically and histologically under light and scanning electron microscopes. The first of the adult insects was collected from Kömüşini, Kulu, Konya, Turkey and the other from Keklikdere, Bingöl, Turkey. According to the results obtained, the female reproductive system in both species consists of a pair of ovaries, lateral oviducts, a common oviduct, spermatheca, bursa copulatrix, and genital chamber. Each ovary has 28 ovarioles in I. speciosus and 50 ovarioles in M. cernyi. In both species, each ovariole consists of a terminal filament, germarium, vitellarium, and pedicel. However, the properties (The number of ovaries, presence-absence of terminal filament, thickness, the length of terminal filament, dimensions of germarium, the number of oocytes in vitellarium, ooplasm content of oocytes, the shape of follicle epithelium surrounding oocytes, the size of oocytes, oocyte surface differentiation) of these parts differ according to the species. In both species, previtellogenesis, vitellogenesis, and choriogenesis stages oocytes were found in the vitellarium. In this study, the similarities and differences in the anatomical and histological structures of the parts of the female reproductive system of I. speciosus and M. cernyi with species belonging to other families were compared.
