Protein content and pattern during mucus gland maturation and its ecdysteroid control in honey bee drones. The species were identified by Prof. Comparative anatomy of the male reproductive internal organs of 51 species of bees. This condition may be related and compensated by the continued spermatogenesis that extends into the adult life stage. Taking into account the possibility that the accessory gland secretion inhibits further matings, the absence of these glands in meliponines might be explained by the species being monoandric.
Megachilidae and evolutionary significance of multiple copulations by females. Organization of the cysts in bees Hymenoptera, Apidae testis: This later portion usually presents anatomic variation among anatmia species.
There was also an increase in distance between the testes and the rest of the internal organs due to the elongation of the post-vesicular deferent ducts, increased production of accessory gland secretion, and a spermatozoa releasing closer to the ejaculatory ducts. Anatomy and physiology of the honey bee. Mate number, kin selection apls social conflicts in stingless bees and honeybees.
In the Apidae with MRA of the Type II, the seminal vesicles differ only slightly from the pre- and post-vesicular deferent ducts, and the post-vesicular ducts open at the final opens at the final portion of the accessory glands, next to the ejaculatory duct Figs.

All the specimens were adults, except for the species Scaptotrigona postica Latreille, Melipona quadrifasciata Lepeletier and Tetragonisca angustula Latreille. Four different types of MRA were found.
Contrary to the solitary bees, however, the meliponine queen produces a much higher number of eggs and is long lived. Yet it is only around the 12 th day of adult life that a drone is mature for mating Snodgrass anato,ia, when all the spermatozoa is contained in the seminal vesicles and ready to be ejected in the female during mating Bishop The functional morphology and biochemistry of insect male accessory glands and their secretions.
The type I is present in males of the less derived families Colletidae, Andrenidae, and Halictidae and is characterized by three seminiferous tubules per testis, which are almost completely enveloped by the scrotal membrane. In this type, the accessory glands are generally well developed Figs. Number of spermatozoa per cyst. The seminiferous tubules are separated from one apid by interstitial tissue; and individually encapsulated by a peritoneal membrane.
A thicker ejaculatory duct allows a higher adhesion to the female during copulation, in addition, the secretion of the accessory glands increases even more melliefra diameter of the ejaculatory duct at the moment of mating and might serve, as anafomia Bombusas a plug that prevents the reflux of sperm or even improves the viability of the sperm posterior to mating BishopSnodgrass The male reproductive apparatus of most insects possesses accessory glands, the mesadenial or ectadenial glands, which open at the deferent apiss or at the ejaculatory duct, respectively SnodgrassChapman Ultrastructure of the ducts of the reproductive tract of males of Melipona bicolor Lepeletier Hymenoptera, Apidae, Meliponini.

The internal genital organs of males of 51 bee species, belonging to six families, were studied Table 1. Material and Methods The internal genital organs of males of 51 bee species, belonging to six families, were studied Table 1.
Therefore, in newly emerged adults, the testes are already undergoing degeneration, appearing as yellowish flat bodies Snodgrass It is characterized by the absence of the anatomis glands and by seminal vesicles that is much thicker than the deferent ducts Fig. Services on Demand Journal. Meliponines are also similar to solitary bees in the sense that they mass provision their brood cells before oviposition and then immediately seal the alveoli Zucchi et al.
The ejaculatory duct is thicker, and, in some species, it may even present a complex pattern, such as longitudinal fissures Figs. The greater development of the seminal vesicles may be an adaptation to the increase in the mllifera and length of the seminiferous tubules and the absence of the accessory glands in stingless bees. The embryology of the honey bee. The function of the accessory glands is melliffra well known in bees. The results allowed separating the 51 species of bees studied into at least four types melkifera organization of the male reproductive apparatus MRA.
A Drosophila male accessory gland protein that is member of the Serpin superfamily of proteinase inhibitors is transferred to females during mating. Excluding the meliponines, and anahomia Type I as the ground plan of MRA, the first major modification of the MRA was the increased development of the accessory gland, which can already be observed in some representatives with Type I.
The bees of the world. Baltimore, The John Hopkins Univ.
Alternatively, the remainder of the ruptured male genitalia in the female tract may anatokia as a plug. Foram obtidos quatro tipos diferentes de ARM. Whereas the tendency in the other families is towards a higher development of the accessory glands, separation of the units encapsulated by the scrotal membrane and an increase sizing and complexity of the ejaculatory duct, the meliponines are characterized by the disappearance of the accessory glands and a general simplification of the genital ducts, including the outer genitalia.
As in type II, the post-vesicular deferent ducts are not encapsulated.
In all species, two portions compose the accessory gland: The type II is an intermediary between types III and I and is present in Melittidae and Megachilidae, as well as in some Apidae studied, being characterized by post-vesicular deferent ducts outside the scrotal membrane and by three or four seminiferous tubules per testis, apiz for Apis mellifera L. In Apis mellifera L.
