Riqueza e abundância de Euglossini (Hymenoptera: apidae) em função de diferentes iscas atrativas em área de mata ciliar na região sul de Mato Grosso do Sul

Abstract

The tribe species Euglossini (Hymenoptera: Apidae) popularly known as orchid bees, represent a group with a relevant importance for the Ciliary Forests conservation and restoration because they are specific pollinators of a great diverse plants, but particularly of the Family Orchidaceae, possessing a strong relation with the flowers of this group. Five genera of Euglossini or orchid bees are recognized: Eulaema, Euglossa, Eufriesea that construct and supply their nests and Exaerete and Aglae that are cleptoparasites of nests of Eulaema and Eufriesea. The objective of this study was to evaluate abundance of Euglossini in the phytophysiognomy of Ciliary Forests and correlating with the attractive baits used (Vanilina, Methyl Cinnamate, Cineol, Eucalyptol, Methyl Salicylate). The research was developed over a period of twelve months and a total od 673 specimens collected. Among all the essences used as attractive baits, Vanilina was the most abundant in Euglossini´s four genera, representing a total of 529 individuals, followed by Eugenol with 46, Cineol with 44, Methyl de Cinamato with 31 and Methyl Salicylate with 23 individuals.
