Despite the biological importance of Meliponini bees, there are still many doubts about their reproductive physiology and phylogeny. When compared with other bee species studied up to now, the reproductive system of Friesella schrottkyi (Friese) has very different characteristics during sexual maturation, which includes: (1) the release of individualized testicular spermatozoa, rather than spermatozoa in bundles, (2) spermatozoa reaching the seminal vesicles only nine days after emersion of the…

The descriptions of new microanatomical structures of the male reproductive system and sperm of Myschocyttarus cassununga (Hymenoptera: Vespidae).
The validity of insect sperm morphology as a tool for phylogenetic analysis within Hymenoptera is supported, and the bilobated mitochondrial derivative represents an autapomorphy for M. cassununga.
Morphology and ultrastructure of the male reproductive system of the jewel wasp, Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae)
The male reproductive system of N. vitripennis was dissected and characterized by light microscopy and transmission electron microscopy, showing that the system follows the pattern of most Hymenoptera species: paired testes with one follicle, deferent ducts, seminal vesicles, accessory glands and a fused ejaculatory duct ultimately connected to the external aedeagus.
Characteristics of the male reproductive system and spermatozoa of leptophlebiidae (ephemeroptera).
This study describes morphological changes in the male reproductive system of Miroculis amazonicus (Savage & Peters) from mature nymphs to subimago stages. The sperm ultrastructure of Massartela
orphology of the male reproductive system and spermatozoa in Centris abricius , 1804 ( Hymenoptera : Apidae , Centridini ) uiz
The genera Centris and Epicharis constitute the Centridini and are widely distributed in the Neotropical region. Centris is also found in the southern portion of the Neartic region, although both
Morphology of the male reproductive system and spermatozoa in Centris Fabricius, 1804 (Hymenoptera: Apidae, Centridini).
Studies on the morphology of the male reproductive system and spermatozoa in Hymenoptera have demonstrated the diversity of the information provided by these reproductive structures, which can be used in taxonomy studies and the phylogeny of this important group of insects.
Anatomy and histology of the male reproductive tract in giant water bugs of the genus Belostoma Latreille, 1807 (Heteroptera, Belostomatidae)
The morphological characteristics of the male reproductive tract in these three species of Belostoma and their similarities with other aquatic Heteroptera are discussed.
Testicular Changes of Honey Bee Drones, Apis mellifera (Hymenoptera: Apidae), During Sexual Maturation
The anatomy and sequential histological stages of normal testicular atrophy of drones sampled daily from emergence to sexual maturity in the spring and early summer are described, finding the rate of testicular maturation was found to change with seasonal progression.
Ultrastructure of male reproductive system of Eurydema ventrale Kolenati 1846 (Heteroptera: Pentatomidae)
The male reproductive system of Eurydema ventrale Kolenati 1846 is studied morphologically and histologically by using light, scanning and transmission electron microscopes. The reproductive system
Sperm Bundles in the Seminal Vesicle of the Crematogaster victima (Smith) Adult Males (Hymenoptera: Formicidae)
The presence of sperm bundles in sexually mature males of Crematogaster victima differentiates C. victima from other ants; however, the similarities in the sperm ultrastructure support the monophyly of this insect group.
Formation of sperm bundles in Pterostichus nigrita (Coleoptera: Carabidae)
Spermiozeugma formation occurs in the upper vas deferens with the secretion of rod material by epithelial cells, which are characterized by well developed rough endoplasmic reticulum with distended cisternae, abundant mitochondria and Golgi bodies.


Internal reproductive system in adult males of the genus Camponotus (Hymenoptera: Formicidae: Formicinae)
This study is the first to provide ultrastructural information on the testes (including spermatogenesis and spermiogenesis), seminal vesicles, and accessory glands in ants, and preliminary analyses indicate that carbohydrate is an important component of accessory gland secretions.
Structure and ultrastructure of spermatozoa in Meliponini (stingless bees) (Hymenoptera: Apidae).
It is concluded that it is possible to define a characteristic pattern for Meliponini spermatozoa, and species-specific differences are found that could be used in a taxonomic or phylogenetic evaluation.
Ultrastructure of the Ducts of the Reproductive Tract of Males of Melipona bicolor bicolor Lepeletier (Hymenoptera, Apinae, Meliponini)
Although the results do not show very consistent morphological signs of secretory activity by the epithelium of these organs, lipidic droplets and lamellar granules present in mature males’ seminal vesicles and the vacuoles present in post‐vesicular vas deferens are probably secretion.
Development of secretory activity in the seminal vesicle of the male migratory grasshopper, Melanoplus sanguinipes (fabr.) (Orthoptera : Acrididae)
In seminal vesicles from allatectomized insects, ultrastructural features of cells and isoelectric focusing patterns of the secretion arc identical to those from normal males.
Ultrastructural organization of the seminal vesicles of Baculum thaii (Phasmida, Phasmatidae) during sexual maturity
It can be affirmed that the seminal vesicles of B. thaii, apart from being the site of the secretory activity necessary for maintaining the sperm in this area, also assume an important role in the processes of “controlling” and “regulating” sexual material that is kept ready for transfer to the female genitalia.

It is mentioned that the Meliponini constructs large honey and pollen pots of characteristic size, and form both In natural hives and in experimental colonies in wooden boxes, showing that their reactions are very variable.
Organization of the cysts in bee (Hymenoptera, Apidae) testis: number of spermatozoa per cyst
The morphology of the cyst cells in Apis mellifera Linne, 1758, Scaptotrigona postica Latreille, 1804, and Melipona bicolor bicolor Lepeletier, 1836 testis, as well as the average number of spermatic
Comparative anatomy of the male reproductive internal organs of 51 species of bees
The anatomy of the internal organs of the male reproductive apparatus (MRA) of adults and pupae was compared among 51 species of bees, including representatives of six families. Four different types
Ultrastructural, histological and histochemical characteristics of the epithelial wall of the seminal vesicle of mature Scaptotrigona xanthotricha moure males (Hymenoptera, apidae, meliponini)
The epithelial cells of the seminal vesicles showed none of the features characteristically associated with a secretory function, which suggested that the material in which the spermatozoa were immersed in the vesicle lumen was produced elsewhere along the ducts and/or during sexual maturation of the males.
Sperm structure and ultrastructure in the Hymenoptera (Insecta)
The presence of well‐developed spermatodesmata in the vas deferens and seminal vesicle characterize the Symphyta and were largely absent from other groups though they are occasionally present in some bees.
