Distribuição de Ninhos de Abelhas Xylocopa (Hymenoptera: Apidae) em uma Área de Dunas Litorâneas

Abstract: -The spatial distribution, density and the types of the substrates used by Xylocopa (Megaxylocopa) frontalis Olivier, X. (Schoenherria) subcyanea Pérez and X. (Neoxylocopa) cearensis Ducke, in a sea coastal sand dune, in Bahia, Brazil, were determined. Both the substrate available and those effectively used by the bees for nesting have a clumped spatial distribution. The distribution of the nesting sites could be related to the clumped spatial distribution of the available substrates. The highest occurrence of… Show more

“…This distribution pattern may be related to the philopatry behavior presented by some Xylocopa species (Camillo & Garófalo 1989) or to restrictions imposed by nesting substrates distribution (Camillo & Garófalo 1989, Gerling et al 1989, Hogendoorn & Velthuis 1993, Da Silva & Viana 2002. The last hypothesis is reinforced by the greater values of the variance/mean index for the Shrub/Clusia area compared to the Restinga Forest formation.…”

“…The analysis of the nesting substrates used by X. ordinaria suggests that there are preferences for certain characteristics and abundance of substrates, independent of botanical affinity, as described for X. frontalis and X. grisescens (Camilo & Garófalo 1982, Pereira 2002, X. suspecta (Camillo et al 1986), X. pubescens (Spinola) (Hogendoorn & Velthuis 1993, 1995, and X. cearensis (Da Silva & Viana 2002. Specificity to host plant species was observed for X. virginica (Linn.…”

“…Além disso, a espécie considerada auto-incompatível necessita de polinizadores que promovam o fluxo de pólen entre plantas, como a abelha solitária Xylocopa suspecta. Desta forma, a produção de sementes resulta da manutenção dos polinizadores efetivos (abelhas solitárias), cuja sobrevivência depende de fontes satisfatórias de recursos, bem como de locais e materiais adequados para nidificação (Silva & Viana 2002). Abelhas A. mellifera não são bons polinizadores de D. alata, pois geralmente não realizam movimento entre plantas e em percentual elevado das visitas pilham néctar.…”

“…Nests of Xylocopa were found in branches of Agarista revoluta (Spr) DC (Silva & Viana 2002), while some of Centridini were found in pre-existent cavities (Viana et al 2001) in the sandy soil of the dunes. These species are multivoltines, presenting high values of temporal niche width.…”
