Cruz Landim, Carminda da Overview.

Most widely held works by Carminda da Cruz Landim. Scanning electronic microscopy of the proventriculus in stingless bees, apidae: Ultrastructure of haemocytes present during flight muscle differentiation of Melipona quadrifasciata anthidiodes, Lepidoptera Hymenoptera, Apidae by Carminda da Cruz Landim 1 edition published in in English and held by 1 WorldCat member library worldwide.

Note on unusual material present in the subperitrophic space of the midgut of mellipona quadrifasciata anthidioides Lep, himenoptera, apidae, melliponinae by Carminda da Cruz Landim 1 edition published in in Portuguese and held by 1 WorldCat member library worldwide.

Apiculture reprint collection Book in English and held by 1 WorldCat member library worldwide. Ultrastructure of the spermathecal gland of Melipona bicolor lep. Hymenoptera, Apinae, Meliponini by Carminda da Cruz Landim 1 edition published in in English and held by 1 WorldCat member library worldwide The ultrastructural features of the spermathecal gland of Melipona bicolor, a stingless bee, are described.

The gland in this species is very small, but the organization of the cells and theis ultrastructural features are very similar to those of Apis mellifera. The gland consist of two short tubular diverticuli connected directly to the spermatheca. The diverticuli are constituted by class III glandular cells. The only difference between the glands of virgin and mated queens is the presence of glycogen deposits in virgins, probably remmants of energetic reserves frequently present in young tissues.

The qhimica role of the secretion of this organ is not known since its lipid morphological aspect, does not seem support a nutritional function composjcao the sperm cells. Spermiogenesis in Palembus dermestoides Coleptera: Tenebrionidae with emphasis on the formation of mitochondrial derivatives by Mara Cristina Almeida 1 edition published in in English and held by 1 WorldCat member library worldwide The testes of Palembus dermestoides are formed by six follicles coated and interconnected by a peritoneal sheath.

Long, cylindrical and slightly twisted spermatophores were observed. Spermiogenesis followed the usual sequence for insects. During spermiogenesis, the nucleus was transferred to the cell periphery and the mitochondria were grouped at the posterior pole of the cell. Two mitochondrial derivatives and two paracrystalline electrondense bodies were present close to the axoneme.

The mitochondrial derivatives were surrounded by a single row of microtubules in immature spermatozoa. Replacement of larval by adult Malpighian suimica during metamorphosis of Melipona quadrifasciata anthidioides Lep.

The dye exclusion test shows generalized celular death in the larvall tubules present in prepupae. The results obtained with the acid phosphatase reaction corroborate these findings. Between the end of larval phase and emergence of adult, the insect does not have functional malpighian tubules, but develops waste storaging cells, the urate cells, for nitrogenous waste inactivation.

The apparent change in the connection point between intestine and malpighian tubules of larva and adult is also discussed. Differences between the female castes and males of scaptotrigona postica depilis, hymenoptera, apidae, meliponinae, in the occurence and altraestructure of tegumentary exocrine glands by Carminda da Cruz Landim 1 edition published in in Portuguese and held by 1 WorldCat member library worldwide.

Electrophoretical studies on protein of hypopharyngeal glands of aged Apis mellifera Hymenoptera: Apidae workers induced to return to brood-feeding activity quuimica Luciana Fioretti Gracioli 1 edition published in in Portuguese and held by 1 WorldCat member library worldwide. Comparative study of the ultrastructure and secretory dynamic of hypopharyngeal glands in queens, workers and males of Scaptotrigona postica Latreille Hymenoptera, Apinae, Meliponini by Rosileia Ana Cassia da Costa 1 edition published in in English and held by 1 WorldCat member library worldwide The secretory cycle of hypopharyngeal glands HPGs in Scaptotrigona postica resembles that of Apis mellifera: The ultrastructural features of the HPG secretory cycle in workers of S.

Then it quimiac suggested that the HPG secrete similar substances in both species.

A second secretory cycle seems to occur in early foragers, may be with production of enzymes. The role of the HPGs in queens and males remains unknown but one possibility is enzyme production. Light and electron microscopic aspects of glands and pseudoglandular structures in the legs of bees Hymenoptera, Apinae, Euglossini by Carminda da Cruz Landim 1 edition published in in English and held by 1 WorldCat member library worldwide The presence of glands and pseudoglandular comopsicao in the legs of male and qiumica of Euglossine bees was studied.

Insect gland cells belonging to class I or class III are present in all pairs of celulz and in all leg segments. Pseudoglandular structures are present in the male pretarsus, which lacked a typical tarsal gland.

A special, probably absorptive epidermis, is present in addition to class III glandular cells in this segment. The basitarsus epidermis has special features which differed from other bees, and males have a tibial organ in the hind pair of legs. Light, scanning and transmission electron microscopy of the component parts of these structures showed that the tibial organ consists of three morphologically distinct parts, which could be distinguished in Euglossa cordata, Eulaema mandibularis and Eufrisea violacens.

Microorganisms of the digestive tract of Brazilian termites Isoptera, Termitidae by Ana M Costa 1 edition published in in English and held by 1 WorldCat member library worldwide The hundgut microbiota of the termites Armitermes euamignathus, Cornitermes cumulans and Anoplotermes sp.

A great variety of bacterial forms were detected and they comprise bacillus, spirochetes and coccus. Negatively stained preparations of the hindgut content showed more than six different bacterial morphotypes including bacteria devoid of flagellum and flagellate.

The number of flagella and their distribution in the bacterial surface is also variable. Types of cells present in the midgut of the insects: Cruz Landim, Carminda da. Portuguese 15 English 8 German 1. Conference papers and proceedings.
