Sôbre Auris bilabiata melanostoma (Moricand, 1836) (Gastropoda, Pulmonata, Bulimulidae)

O autor redescreve Auris bilabiata melanostoma (Moricand), utilizando exemplares vivos colecionados no Estado do Rio. Além do estudo da genitália, câmara paleal e rádula, analisa variações das conchas de várias proveniências. Chama a atenção para a necessidade de estudos comparativos das partes moles para uma conclusão definitiva, sôbre a validade das duas subespécies (bilabiata s. st. e melanostoma).

First report of Mazocroeoides georgei price, 1936 and Mazocraeoides opisthonema Hargis, 1955 in Brazil with new synonysms (Monogenea, Mazocraeidae)

Mazocraeoides georgei price, 1936 and mazocraeoides opisthonema Hargis, 1955 are reported for the first time in Brazil in Brevoortia aurea (Spix, 1829) and in Harengula clupeola (Cuvier, 1829) respectively, clupeid fishes from the littoral of Rio de janeiro State, which represent new host records. Mazocraeoides olentangiensis Sroufe, 1958 and mazocraeoides hargisi Price, 1961 are considered new synonyms for Mazocraeoides georgei.

Re-descriptions of Isospora ameivae Carini, 1932 in the Teiid Lizard Ameiva ameiva and Isospora hemidactyli Carini, 1936 in the Gecko Hemidactylus mabouia, with Particular Reference to their Endogenous Stages

Redescriptions are given of the mature oocysts of Isospora ameivae Carini, 1932, from the teiid lizard Ameiva ameiva, and Isospora hemidactyli Carini,1936 from the gecko Hemidactylus mabouia, in north Brazil. The endogenous stages of the two parasites in the small intestine are described. Those of I. ameivae are intracytoplasmic, whereas those of I. hemidactyli are intranuclear.

The fine structure of the endogenous stages of Isospora hemidactyli carini, 1936 in the gecko Hemidactylus mabouia from North Brazil

The ultrastructure is described of the meronts, microgamonts and young oocyst stages of Isospora hemidactyli of the gecko Hemidactylus mabouia from Belém, PA, north Brazil. The endogenous stages all develop in the nucleus of the gut epithelial cells. The nucleus remains intact up to the latest stages of the parasite's development, but degenerates by the time the oocyst appears. Merogonic division appears to be asynchronous, and some of the differentiated merozoites contained more than one nucleus. Microgamonts conform in structure with those of other eimeriids. Some of the type 2 wall-forming bodies disintegrate into smaller globules and ground substance of lower density.

Characteristics of the bological cycle of Lutzomyia evandroi Costa Lima & Antunes, 1936 (Diptera: Psychodidae) under experimental conditions

Lutzomyia evandroi Costa Lima and Antunes, 1936 is found in Rio Grande do Norte, northeastern Brazil, in areas of visceral and mucocutaneous leishmaniasis and follows the same geographic distribution of L. longipalpis. The biological cycle, oviposition, morphological and behavioral characteristics of the species were studied under experimental conditions. The average number of eggs per wild caught female varied from 21 to 50 eggs along the year, with a peak occurring between January and March and another in August, with oviposition lasting for 4 to 12 days. The mean larval phase was 24 days. Ovipositing rates were influenced by rainfall and temperature indexes, with an increase of eggs per oviposition at the beginning and at the end of the rainy season, and a decrease at the peak of the rainy season.

Redescrição de Litomosoides brasiliensis Almeida, 1936 (Nematoda: Filariidae) Parasito de Anoura caudifera (Chiroptera: Phyllostomidae)

The study of the surface topography added details regarding the disposition of male caudal papillae, spicules and area rugosa apart from vulva and oral aperture. The occurrence of this nematode in the state of Amapá represents a new geographical distribution.

Odontopus brevirostris (Hustache, 1936) (Coleoptera, Curculionidae) associated with new host plants belonging to Annona (Annonaceae)

Odontopus brevirostris (Hustache, 1936) feeding on Annona squamosa L., A. cherimola Mill., A. glabra L., and A. muricata L. was observed. The last three host plants are recorded for the first time. The endophitic oviposition occurs in the veins of the ventral surface of the young leaves. The larvae, leaf miners, eat the parenchyma and the adults make small holes in the leaves. The pupation occurs in spherical cocoons protected by a sort of nest (pupation chamber) between the two epidermal layers.

O ensino da química na Escola Superior de Agricultura "São Bento", Olinda - São Lourenço da Mata - Pernambuco (1912-1936)

The present work proposes the investigation of the role of chemistry in the curriculum of the Higher School of Agriculture "São Bento" (1912-1936) and its function in the education of agronomic engineers. The circumstances under which the Higher Schools of Agriculture and Veterinary Medicine in Olinda were founded at the beginning of the XXth century are discussed. The article further treats the influence of the principles of Justus von Liebig, which were seen at that time as essential for a rational agriculture.
