Revista Brasileira De Zoologia, 2004 Nests of Centris tarsata Smith, 1874 were obtained from trap-nests in areas of dry semi-deciduous forest (Baixa Grande) and caatinga (Ipirá), in the State of Bahia. Nesting occurred in bamboo canes and in tubes of black cardboard with 5.8 cm (= small tube) and 10.5 cm (= large tube) in length and 0.6 and 0.8 cm in diameter, respectively.

Nesting biology of Centris (Centris) aenea Lepeletier (Hymenoptera, Apidae, Centridini) [PDF]
Revista Brasileira De Zoologia, 2003 Nesting activity of Centris aenea Lepeletier, 1841 was studied in two Brazilian habitats, Caatinga (Monte Santo, Bahia) and Cerrado (Palmeiras, Bahia and Luiz Antonio, Sao Paulo). Nests were excavated in the ground and did not tend to be aggregated together at the two sites, but at Palmeiras, nests were in a large aggregation.

Nesting biology of Centris (Hemisiella) vittata Lepeletier in southeastern Brazil (Hymenoptera, Apidae, Centridini) [PDF]
Apidologie, 1999 Nests of Centris vittata were obtained from trap-nests at Santa Carlota Farm, Cajuru, SP, Brazil. The bees nested in bamboo canes ranging from 8.5 to 24.7 cm in length and from 0.9 to 1.9 cm in diameter. The bees constructed their nests with a mixture of soil and an oily substance. Com- pleted nests had 1-8 urn-shaped cells arranged in a linear series,

Natural enemies are one of the main mortality factors in bees and wasps attacking either immature stages or adults of their hosts. Dipterans of the genus Physocephala (Diptera: Conopidae) are parasitoids that attack adult bees during their field activities, and the parasitoid larvae develop inside the host abdomen.
