Cephalic salivary glands of two species of advanced eusocial bees (Hymenoptera: Apidae): morphology and secretion
Provedor de dados: 103
Autores: Poiani,Silvana B.; Cruz-Landim,Carminda da.
Some adult eusocial bees have a pair of cephalic salivary glands (CSG) in addition to the thoracic labial or salivary gland pairs. This paper deals with variations in morphological features and secretion production of the CSG of females and males of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807. The following life stages were studied: newly emerged, nurse, and forager workers; newly emerged and egg-laying queens; and newly emerged and sexually mature males. The histological results showed that the CSG differs between the two species in the following features: while alveoli and duct cells are cuboidal in workers and queens of A. mellifera, they change from cuboidal to flat in S. postica as the workers age. The glands of newly...

There are report two human envenenomations for species from Clelia Fitzinger, 1826 (opisthoglyph snake). The patients exhibited symptoms similar from bothropic accident. Then this work have with objective, the hystological and histochemical study of Duvernoy's gland from Clelia plumbea. For the hystological observation of the Duvernoy's gland were using, with paraffin's cutting edge, two methods: Hematoxylin + Eosin and Toluidine's Blue. With historesine's cutting edge were using three methods: Metilen's Blue, Toluidine's Blue + Floxine and Toluidine's Blue. For the histochemical detection were using six techniques, with paraffin's cutting edge: PAS, PAS + Alcian Blue pH 2,5, Alcian Blue pH 2,5, PAS + Salivar Amilase, Method of Lars Grimelius and Method of...
