ESPÉCIES VEGETAIS DA CAATINGA ASSOCIADAS ÀS COMUNIDADES DE ABELHAS (Hymenoptera: Apoidea : Apiformis)

Abstract

This work was carried out in an area covered by the caatinga (savanna-like) vegetation in order to study insect-plant interactions, with emphasis on the pollination agents of the Apoideae superfamily. The study site is situated in the municipality of Caturité, Paraíba, Northeast Brazil (7o 25' 12" S; 36 o 1' 37" W). Plant species visited by bees were identified, as well as the Hymenopterans considered as their visitors. Sixteen Angiospermae species from nine families were identified as being associated to bees in the woody and herbaceous strata. The most visited plant families were Fabaceae (50%) and Anacardiaceae (12.5%). Anandenanthera macrocarpa (Benth) and Senna spectabillis had the greatest numbers of visitors (85% and 57% respectively). Among the pollinating bees, the one which visited more plant species was Trigona spinipes (Fabricius). It was found visiting 81.25% of the plant species under study.
