Macroscopic and Histological Structures of Testes in Three Different Tentyria Species
Abstract
The male reproductive
organs in insects are typically composed of a pair of seminal vesicles and a
pair of test tubes joined to the excretion channel on the median line. The
samples used in the study were collected from İzmir Bozdağ region and from
Turkish Republic of Northern Cyprus. All
testis samples were fixed in Bouin’s solution and Mayer’s Haematoxylin-Eosin
(H&E) was used to stain for tissue section. As a result of the macroscopic examinations, it was
determined that the testis appearance of Tentyria
cypria is different from other species used in the study. At the end of the
histological examinations, the general appearance of the T. cypria’s testis was similar to a four-leafed clover. In all
three species, spermatogonia, primary spermatocytes, secondary spermatocytes,
spermatids, and spermatozoa, which are the stages of spermatogenesis in all
follicles, are clearly visible. In this study, morphological and
histological differences in male reproductive organs were demonstrated for the
first time in three different Tentyria
species belonging to Tenebrionidae family.
