REZENDE DINIZ, Ivone  and  KITAYAMA, Kiniti. Seasonality of vespid species (Hymenoptera: Vespidae) in a central Brazilian cerrado. Rev. biol. trop [online]. 1998, vol.46, n.1, pp.109-114. ISSN 0034-7744.

Foraging habitats as well as the fluctuations in vespid species abundance in Mato Grosso State, Brazil, were determined, through sampling effort per hour per collector in four cerrado sensu lato habitats, "campo úmido" (Cu), "campo sujo" (Cs), "cerrado sensu stricto" (Css), and "gallery forest" (Mg), during four periods consisting of two dry (August 1988 and June 1989) and two wet (October and December 1988) season periods. For "campo úmido", some species seem to be highly seasonal, either in the dry or wet seasons, whereas very few species occur year-round. The abundance, species composition and richness varied between habitats types and between seasons.

Keywords : Vespidae; foraging habitats; seasonality; cerrado; Brazil.
