Abstract

Male euglossine bees attracted to cineole, vanillin, methyl salicylate, eugenol and benzyl benzoate, were collected from October 1995 to September 1996, twice a month, between 06.00 and 12.00 hours, at the Companhia Vale do Rio Doce Forest Reserve, Buriticupu-MA. It were sampled 1740 individuals, 37 species and 4 genera. Euglossa was the most abundant genus (23 species), followed by Eufriesea (8), Eulaema (4) and Exaerete (2). The most frequent species were Euglossa pleosticta (33% of the collected individuals), Euglossa truncata (12,7%), Euglossa avicula (6,3%), Eufriesea superba (5,2%), Euglossa fimbriata (4,8%) Euglossa violaceifrons (4,4%), Eulaema nigrita (4,1%), Euglossa cordata (4,0%), Eulaema meriana (3,4%). Cineole attracted 66% of males and 70% of species, vanillin (20%; 59%), methyl salicylate (7,4%; 54%), eugenol (5,6%; 44%) and benzyl benzoate (0,7%; 10,8%). The highest abundance of individuals (78,3%) and species (34) occurred in the rainy season (January-June). The species of the genus Eufriesea occurred only in this period. Regarding the hourly activity, the euglossine bees were more frequently found between 10.00 and 11.00 hours, accounting for 33,5% of the individuals and 86,4% of the species.Machos de Euglossinae atraídos por cineol, vanilina, salicilato de metila, benzoato de benzila e eugenol, foram coletados de outubro de 1995 à setembro de 1996, quinzenalmente, das 06:00 às 12:00 horas, na Reserva Florestal da Companhia Vale do Rio Doce (CVRD), em Buriticupu-MA. Foram coletadas um total de 1740 indivíduos pertencentes a 37 espécies de 4 gêneros. Euglossa foi o mais comum (23 espécies), seguido por Eufriesea (8), Eulaema (4) e Exaerete (2).
