Macias Macias J O; Quezada-Euán J J G (2015) Stingless bees in a temperate climate: oviposition behavior and duration of ontogenic development stages in Melipona colimana (Hymenoptera: Meliponini). J. Apicultural Res. 54: 255-259


Melipona colimana is a stingless bee endemic to temperate areas of the Trans-Mexican volcanic belt, where intranest behavior during the provisioning and oviposition process, duration of ontogenic development stages and time of emergence of individuals were determined. It was observed that the dynamics of provisioning and oviposition do not differ substantially from tropical species of the same genus, but ontogenic development in a temperate climate was longer than in a tropical climate, possibly due to lower temperatures in the original habitat of the species. Duration of ontogenic
development of M. colimana individuals is the longest recorded so far among the species of Melipona genus. Worker bees took 55.44 ± 1.09 days to emerge from the cells; males, 57.14 ± 0.94 and gynes, 52.62 ± 0.63, with statistical differences between them (F = 367.72, DF = 2, 395, p < .05). The gynes emerged before workers, and workers before the males. The obtained data can be used to promote the sustainable use of this species in mountains in Mexico.
