Trap-nests for stingless bees (Hymenoptera, Meliponini)

Most stingless bee species build their nests inside tree hollows. In this paper, we present trap-nest containers which simulate nesting cavities so as to attract swarms of stingless bees. Although regularly used by stingless bee beekeepers in Brazil, this technique to obtain new colonies has not yet been systematically studied. We used two different types of trap-nests (plastic and cardboard) of four different sizes (0.5, 1.0, 2.0, and 3.0 L) containing propolis extract and wax. Over a period of 2 years, 61 swarms of nine different stingless bee species were attracted to the trap-nests. Most swarms chose the largest container (3 L); swarms were collected mostly in springtime (October-December). The plastic containers were more successfully occupied than others by stingless bee swarms. Trap-nests are a viable tool for stingless beekeepers, researchers and conservation biologists to obtain and study stingless bee colonies.
