Pollen foraging in colonies of Melipona bicolor (Apidae, Meliponini): effects of season, colony size and queen number

S. D. Hilário and Imperatriz-Fonseca, V. L., Pollen foraging in colonies of Melipona bicolor (Apidae, Meliponini): effects of season, colony size and queen number, vol. 8, pp. 664-671, 2009.

We evaluated the ratio between the number of pollen foragers and the total number of bees entering colonies of Melipona bicolor, a facultative polygynous species of stingless bees. The variables considered in our analysis were: seasonality, colony size and the number of physogastric queens in each colony. The pollen forager ratios varied significantly between seasons; the ratio was higher in winter than in summer. However, colony size and number of queens per colony had no significant effect.
