CAMILLO, Evandro. Inquilines of Brachymenes dyscherus nests with special reference to Monobia schrottkyi (Hymenoptera, Vespidae, Sphecidae). Rev. biol. trop [online]. 2001, vol.49, n.3-4, pp.1005-1012. ISSN 0034-7744.

Sixty-four inactive nests of the solitary mud-daubing wasp Brachymenes dyscherus, reused by 5 inquiline species, were collected at Fazenda Santa Carlota, Cajuru, São Paulo, Brazil in 1995 and 1996. Monobia schrottkyi used 52 nests; among the 717 cells available for use, 502 were reused. The number of cells per nest varied from 3 to 24; 1 to 16 individuals emerged from September to April (154 males and 112 females). Forty-six cells were parasitized by Melittobia sp. (n = 44) and Ichneumonidae (n = 2). Monobia curvata used 3 nests; among the 50 cells available for use, 38 were reused and 15 males and 8 females emerged from August to November. Three cells were parasitized by Ichneumonidae. Montezumia petiolata occupied 1 nest; among the 8 available cells, 7 were reused and 2 males and 3 females emerged in September. Podium denticulatum used 2 nests; the 20 cells available for use were reused and 11 males and 4 females emerged in August. Trypoxylon rogenhoferi used 5 nests that had 65 available cells; 48 of them were reused, from which 19 males and 11 females emerged from September to November. Three cells were parasitized by Ichneumonidae (n = 2) and Chrysididae (n = 1)
