Geographic Range and Nest Architecture of Cephalotrigona Capitata Smith, 1854 (Apidae: Meliponini) in the State of Bahia, Northeastern Brazil

Abstract

The bees of the genus Cephalotrigona (locally known as “mombucas”) play a key role in natural environments but their bioecological features, required to design proper management and conservation strategies, are scarce in most species. Thus, the goal of the present study was to map the occurrence sites of C. capitata in the state of Bahia, north-eastern Brazil, and to provide useful information about nest architecture to their technical management. This species was recorded in fifteen municipalities in Bahia, totaling forty-one nests. The range of C. capitata varied from locations at sea level to seasonal ombrophilous forests at an altitude of 600 m high. The nests were built in trees with a mean diameter of 19.8 ±3.0 cm. The nest architecture was similar to that reported in other stingless bee species, with a variation in analyzed parameters. The thermoregulation was more efficient in highly populated boxes. The present results can be used for the conservation and management of this species, which represents a potential source of income for local farmers.
