Abstract：
:A morphological and ultrastructural study was carried out on the spermatophore and spermatodoses of some species of Orthoptera Tettigoniidae. From the results concerning the spermatophore it emerged that this structure has a morphological and ultrastructural organization represented by a dilated ampulla and a peduncle or neck. From the examination of freshly deposited spermatophores and those at various time intervals thereafter, it was seen that these structures other than allowing gamete transfer, represent the site where spermatodesms, organized in the male genital tracts, undergo reorganization to acquire their definitive morphological and structural characteristics as found in the female genital tracts. The spermatodoses, in the same way as the spermatophore, represent capsules containing spermatodesms, which are originated in the spermatheca, their specific morphology seems to diversify according to the species considered. As regards their role, it is hypothesized that these structures represent a long-term conservation mechanism for spermatozoa inside the seminal receptacle.
