Biologia de Centris Fabricius (Hymenoptera, Anthophoridae, Centridini) em matas contínuas e fragmentos na Amazônia Central Zoologia
Morato,Elder F.; Garcia,Marcos V. B.; Campos,Lúcio Antônio de O..
A study of four tree-hole nesting bee species of Centris Fabricius, 1804 was conducted between July, 1988 and June, 1990 in isolated and continuous "terra firme" forests at Manaus region. Nests were obtained from wood trap-nests of different diameters and consisted of a linear series of brood cells. Centris dichrootricha (Moure, 1945) and C. terminata Smith, 1874 were the most abundant species. Centris terminata nested principally in gaps and continuous forest and C. dichrootricha in cleared areas and small fragments of forest. More nests were obtained in trap-nests placed at 8 and 15 m height above ground. Nesting activity was more pronounced in the wet season between August and January. Natural enemies are the beetle Tetraonyx Latreille, 1805 and the...

Efeitos da fragmentação florestal sobre vespas e abelhas solitárias em uma área da Amazônia Central Zoologia
Morato,Elder F.; Campos,Lúcio Antônio de O..
The effects of forest fragmentation on tree-hole nesting solitary wasps and bees were investigated at a site 90 km north of Manaus, Brazil. Wasp and bee faunas were monitored in continuous terra firme forest, forest fragments of 1, 10 and 100 ha, natural gaps in continuous forest and deforested areas. These habitats were studied in terms of abundance, richness, diversity and similarity. The wasps and bees were monitored monthly during June 1988 through June 1990 by means of a trap-nests technique. A total of 1529 nests of wasps of 24 species and 405 nests of bees of 14 species were collected. The number of species of wasps and bees varied little among the habitats. The genus Trypoxylon Latreille, 1796 (Sphecidae) accounted for 79% of wasp nests and Centris...

Partição de recursos florais de espécies de Sida Linnaeus e Malvastrum coromandelianum (Linnaeus) Garcke (Malvaceae) entre Cephalurgus anomalus Moure & Oliveira (Hymenoptera, Andrenidae, Panurginae) e Melissoptila cnecomala (Moure) (Hymenoptera, Apidae, Eucerini) Zoologia
Morato,Elder Ferreira; Campos,Lúcio Antônio de O..
The flowering pattern and the visiting bee species on Sida spp. and Malvastrum coromandelianum (L.) Garcke were studied in a restricted area at the campus of the Universidade Federal de Viçosa, Minas Gerais, Brazil. There were differences among plant species but not among individuals in relation to the flowering time along the day and the time at which the flowers were visited by bees. Melissoptila cnecomala (Moure, 1944) and Cephalurgus anomalus Moure & Oliveira, 1962 were the most frequent visitors. Both species foraged on flowers for nectar and pollen. C. anomalus visited mainly plants with anthesis in the morning and M. cnecomala plants with anthesis in the afternoon. This fact sugests that those species of bees may be showing contrasting...
