Note on bees Lestrimelitta rufipes (Friese) (Hymenoptera, Meliponina) attracted by scent traps in the South Region of the State of Rio de Janeiro

Abstract

This study was done each two months between August 2006 to May 2007 in a South Region in the State of Rio de Janeiro. The traps, a (Carvalho-47) model, were adjusted, then assembled at 9 o'clock and finally removed 48 hours after. In each place of the extraction, 4 traps were assembled, in a total of 20 in all the trail. During the experiment, eight worker bees of Lestrimelitta rufipes, were captured, and seven of them were attracted by methyl salicilate and one by cineole. Beside this essences, two more were used, eugenol and vanillin, but these two ones didn't collect any bees. All the bees were collected during November 2006. Even with such geographical distribution, L. rufipes hasn't been registered in this south region, and this is also the first registered collection of this specie using scent traps. It was not possible to identify the cause of the bee workers L. rufipes attraction by methyl salicilate and cineole, because these bees do not visit flowers, neither nets that could have this fragrance. The method of collection used by scent traps can be used for many purposes and among them the objective of knowing the richness and distribution of these types in different areas.
