Estudos sobre o gênero Melipona

Abstract: 1° - Cita-sé a evolução das abelhas segundo MICÍÍENÉR" (1944). 2.° - A evolução dos Melíponíneos é estudada sob o ponto de vista da sua biologia, estabelecendo-se o tipo do meliponíneo primitivo. 3.° - São feitas considerações sobre a distribuição geográfica dos meliponíneos, entrando-se em detalhes sobre os seus fosseis, sobre a influência dos deslocamentos geológicos do cenozoico sobre sua distribuição, com particular referência ao seu estabelecimento na América do Sul. Considera-se também o e$eito das glaci… Show more

“…This study also fully confirmed the earlier findings on the absence of accessory glands in the male reproductive tract of Meliponini (Kerr, 1948). The spermatozoa in the male ducts are immersed in seminal fluid, which, like in the honey bee, is probably a secretory product of epithelial cells in the walls of the large seminal vesicles, and there is no evidence for other secretory cells, according to an ultrastructural analysis of the male reproductive tract in Melipona bicolor bicolor (Dallacqua and Cruz-Landim, 2003).…”

“…Leopold (1976) and Chapman (1998) mentioned the presence of male accessory glands among the insects with either an ectodermal or a mesodermal origin. In Meliponini the male accessory glands are absent (Kerr, 1948;Ferreira, 1966). Sometimes the role of male accessory glands is taken over by glandular cells of seminal vesicles, vas deferens or ejaculatory duct (Riemann, 1973;Gillot and Friedel, 1976).…”

“…Only a few publications exist on the Melipona karyotype in general and particulary on that of M. quadrifasciata anthidioides. Kerr (1947) found 18 chromosomes in females and 9 in males in preparations from the nervous tissue of larvae. Classifications of these chromosomes were proposed by Tarelho (1973) and Tambasco (1975) on the material obtained through squash of the germinative tissue.…”
