Última Ocorrência e morfologia de glândulas tegumentares no abdome de algumas abelhas (Hymenoptera: Apidae): um estudo comparado Neotropical Entomology Guerino,Adriane C.; Cruz-Landim,Carminda da. No presente trabalho foi estudada a ocorrência, distribuição e morfologia de glândulas tegumentares do abdome em Exomalopsis auropilosa Spinola, Centris fuscata Lepeletier, Epicharis flava Friese e Xylocopa (Neoxylocopa) suspecta Moure & Camargo. Os resultados mostraram a ocorrência de glândulas epiteliais (classe I) e unicelulares (classe III) com distribuição dorsal (tergais) e ventral (esternais) sem que se pudesse caracterizar um padrão relacionável com a posição filogenética ou grau de sociabilidade. No entanto, verificou-se uma tendência para maior número de glândulas em espécies com algum grau de sociabilidade como E. auropilosa e X. suspecta.

Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-566X2003000200010 Ultra-estrutura de glândulas abdominais tegumentares em Oxaea flavescens (Hymenoptera, Andrenidae, Oxaeinae) Iheringia, Sér. Zool. Guerino,Adriane Cristina; Cruz-Landim,Carminda da. The sternal glands of the abdomen of Oxaea flavescens (Klug, 1807) consist of class III glandular cells around a reservoir constituted by branched folds of the intersegmental membrane of segments III, IV and V. The gland cells are rich in rough endoplasmic reticulum and produce a secretion with mucous aspect. The treatment with oxidated osmium and ruthenium red showed numerous Golgi regions in the cell and carbohydrates absorption from the haemolymph, respectively. The high degree of development of the glands suggests an important function to the species, although still unknown.

Zool. Oliveira,Vagner T. Paes de; Cruz-Landim,Carminda da. Workers of Melipona quadrifasciata anthidioides (Lepeletier, 1836) develop their ovaries and lay eggs, therefore the production of vitellogenin is expected. In electrophoretic profiles only fat body extracts from nurse workers and ovary extracts from newly-emerged workers show protein with molecular mass similar to vitellogenin. However, an increase in the protein content was detected in forager fat body. This increase was attributed to storage of vitellogenin or other proteins in the previous phase and not discharged into the hemolymph or to an effect of the increased titre of juvenile hormone in this phase of worker life over the fat body functioning.

Zool. Patrício,Karina; Cruz-Landim,Carminda da. The occurrence of cell reabsorption in the ovaries of queens in several rates of laying eggs, artificially impeded of laying, and in nurse workers, of Apis mellifera (Linnaeus, 1758), was studied with light (LM) and transmission electron microscopy (TEM). Two types of structures were described and named by analogy with vertebrates ovarian structures, as corpus luteus, when resulting from the reabsorption of the follicular cells after ovulation, and corpus atresicus when resulting from total follicular reabsorption at any oocyte developmental stage. These structures have the same morphological characteristics and physiological signification in both castes. The corpus luteus occurrence indicates ovulation and its number is correspondent to the queen's rates...

Zool. Poiani,Silvana B.; Cruz-Landim,Carminda da. O vaso dorsal é um órgão tubular localizado na região mediano-dorsal do corpo dos insetos, abaixo do tegumento. Fez-se um estudo de microscopia de luz e eletrônica de transmissão da porção abdominal do vaso dorsal, o coração, em uma espécie de abelha indígena. Foram estudadas operárias e rainhas em diferentes idades. O coração está localizado no sinus pericárdico. A parede cardíaca é formada por fibras musculares estriadas e apresenta aberturas ou ostíolos providos de válvulas. A fibra cardíaca contém miofibrilas arranjadas irregularmente, núcleos alongados ou redondos, mitocôndrias grandes e numerosas, e depósitos de glicogênio. Em operárias e rainhas longevas, as fibras encontram-se em degeneração, evidenciada por vacúolos autofágicos, alterações...

Bras. Zool. Poiani,Silvana B.; Cruz-Landim,Carminda da. The bee species of the Apinae, in addition to the thoracic salivary glands, possess a pair of cephalic glands originating as branches of the excretory duct that crosses the head. These glands are known as cephalic salivary or labial cephalic glands. The degree of development of these glands in newly emerged, nurse and forager workers and virgin and egg-laying queens of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807 were evaluated by measuring the secretory alveolar units. The area of the secretory alveoli, measured in total gland preparations, was used to evaluate differences in size. In both species, gland size was found to increase progressively from newly emerged workers to foragers and from virgin to egg-laying queens. A...

Bras. Zool. 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... Tipo: Info:eu-repo/semantics/article Palavras-chave: Apis mellifera; Histochemical; Labial gland; Lipid; Scaptotrigona postica.

Bras. Zool. Poiani,Silvana Beani; Cruz-Landim,Carminda da. ABSTRACT Secretory cells of the cephalic salivary glands (CSGs) of eusocial bees produce and accumulate lipid-like secretion in the lumens of their alveoli. Correspondingly, secretory cells present typical ultrastructural features of lipid-compound producers. Previous work on bees has revealed inter-specific differences in the chemical composition of secretion, and the production mechanisms and secretory cycle of secretory cells. In this work a comparative analysis of the mechanisms of lipid storage in the CSGs of Apis mellifera (Linnaeus, 1758) and Scaptotrigona postica (Latreille, 1807) workers was carried out. The ultrastructural location of lipids was ascertained using imidazole-osmium (IO), using individuals in different stages of their life cycles....

(Hymenoptera: Apidae) promoted by topical application of juvenile hormone Neotropical Entomology Roat,Thaisa C.; Nocelli,Roberta C.F.; Cruz-Landim,Carminda da. The present study analyzed, the influence of the treatment with juvenile hormone on the ultrastructure of Apis mellifera L. workers' venom glands. Newly emerged workers received topical application of 1 µl of juvenile hormone diluted in hexane, in the concentration of 2 µg/µl. Two controls were used; one control received no treatment (group C1) and other received topical application of 1 µl of hexane (group C2). The aspect of the glandular cells, in not treated newly emerged workers, showed that they are not yet secreting actively. Cellular modifications happened according to the worker age and to the glandular area considered. The most active phase of the gland happened from the emergence to the 14th day. At the 25th day the cells had already lost their... Tipo: Info:eu-repo/semantics/article Palavras-chave: Secretory cycle; Glandular degeneration; Hexane; Bee.

Ovários de Anopheles triannulatus foram dissecados 24 e 48 horas após as fêmeas terem sido alimentadas com fonte protéica (sangue), afim de se estudar o seu efeito sobre a ovogênese. Foram analisadas secçõees hisiológicas, ao nível da ultraestrutura, e observadas as mudanças morfológicas que ocorrem nas interfaces células foliculares-ovócito e célula folicular-célula. Foram observados aspectos estruturais que corroboram a hipótese da produção exógena das proteínas do vitelo. Os grânulos de vitelo originaram-se principalmente por condensação das vesículas pinocíticas formadas na superfície do ovócito.

Both castes of Scaptotrigolia postica (Latreille, 1804) possess four ovarioles in each ovary. Queen and workers have the same ovarian development during the larvallife, but in lhe late larval stage the queen ovary beco me larger. During pupation a higher rate of cell division is observed in queen ovarioles and a higher rale of cell death in workers. Newly emerged workers have short ovarioles with differenriatcd germarium and vitellarium while queens have very long ovarioles with only germarium.
