Abstract

Twenty-six nests of Megachile guaraniticaSchrottky were obtained during a study of trap-nesting bees and wasps in a forest remnant surrounded by crop areas in the central-western region of SAo Paulo State, Brazil. Fieldwork was performed monthly from June 2011 to May 2013. Females of M.guaranitica nested during the hotter/wetter season, from December to March. Brood cells consisted of three layers: an outer one made with oblong pieces of leaves, a thick middle wall of mud and an inner layer of oblong pieces of leaves. Pollen analysis of the contents of 10 nests revealed the dominance (97.6%) of pollen from the subfamily Mimosoidae (Fabaceae). The immature stages underwent prepupal diapause and took approximately 277 days to emerge. Seventeen of the 26 nests (65%) were attacked by the cleptoparasite Coelioxys bertonii Schrottky, and more individuals of this species (69%) emerged than females and males of the host species (31%). Coelioxys bertonii also underwent prepupal diapause, with development lasting approximately 240 days. The parasitoid wasp Melittobia australica Girault (Eulophidae) is recorded as a parasitoid of M. guaranitica. (AU)
