Biologia de Centris Fabricius (Hymenoptera, Anthophoridae, Centridini) em matas contínuas e fragmentos na Amazônia Central

Biology of Centris Fabricius (Hymenoptera, Anthophoridae, Centridini) in continuous forest and fragments in Central Amazonia

Resumo

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 bees Coelioxys Latreille, 1809, Mesocheira Lepeletier & Serville, 1825 and Mesoplia Lepeletier, 1841. Nest architecture of Centris spp. are described.

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.
