Última Comparative analysis of morphological, structural and morphometric patterns of Polistes versicolor (Olivier) (Hymenoptera: Vespidae) hypopharyngeal glands Neotropical Entomology Britto,Fábio B.; Caetano,Flávio H.; Moraes,Regina L.M.S. de. Using ultramorphological and histochemical techniques, this study describes the structural and morphological patterns of Polistes versicolor (Olivier) hypopharyngeal glands, comparing them with patterns of other Hymenopteran groups. Besides, the presence of intra-specific variation was evidenced by morphometric analysis of the secretory cells in wasps with different ages. The studied species presented glands with primitive characteristics, with secretory cells discharging individually in the hypopharyngeal plate. The morphological pattern found in hypopharyngeal glands was basically the same for all studied wasps, however, the length of glandular cells showed significant variations between individuals. Apparently these variations are not related with age. Tipo: Info:eu-repo/semantics/article Palavras-chave: Wasp; Salivary system; Evolution; Morphology; Morphometry. Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-566X2004000300007 Ultramorphology and histology of the larval salivary gland of Pachycondyla villosa (Fabricius) (Hymenoptera: Formicidae, Ponerinae) Neotropical Entomology Zara,Fernando J.; Caetano,Flávio H.. The salivary gland possesses a single anterior duct with a columnar epithelium, two lateral ducts with simple cubical epithelium, which becomes columnar in the proximal portion, and two thin-walled reservoirs, from which two secretory regions arise. The dorsal and ventral branches of the secretory regions are connected via transverse commissures and ends in a loop. The secretory region is uniform and consists on a simple cubical epithelium. This paper also presents a review on the morphology of the salivary glands in insects, mainly in Hymenoptera-Aculeata.

The salivary system of the Hymenoptera consists of the mandible, hypopharynx and thoracic salivary glands. It is very important because it is related to various aspects of the life of the insects, such as pheromone production, feeding the young, food digestion and nest building. Adult Polistes versicolor (Olivier) individuals were dissected, the thoracic salivary glands removed and processed for scanning electronic microscopy and histological examination. The P. versicolor thoracic salivary gland presents alveolar secretory units, consists of pseudoacines and does not have a reservoir. Four types of cells are present in the gland. The T1 and T2 cells make up the pseudoacines and differ mainly by the many secretory vessels in T2. There is a cluster of T3...

Speg. var. falcata (Benth.) Altschul (Leguminosae-Mimosoideae) Rev. Bras. Bot. Gross,Eduardo; Cordeiro,Lázara; Caetano,Flávio H.. A. peregrina var. falcata form mutualistic symbiosis with arbuscular mycorrhizal fungus. An anatomical and ultrastructural study was carried out to analyze some aspects of this simbiotic association as well as some root features. The results evidenced the presence of fibers with non-lignified thicked secondary walls in the stele and sparse papillae on root surface. A. peregrina var. falcata mycorrhizas presented features of Arum-type (intercellular hyphae) and Paris-type (extensive coils) arbuscular mycorrhiza. Their general appearance with extraradical hyphae, intracellular coils, intercellular hyphae and arbuscules, is in agreement with arbuscular mycorrhizas of several plants. The ultrastructural observations showed that in intercellular hyphae and...
