Environmental Factors Influencing Foraging Activity in the Social Wasp Polybia paulista (Hymenoptera: Vespidae: Epiponini)
Number of foragers that arrived at the nest every 15 minutes in relation to season and temperature. There is a clear influence of temperature on foraging for both. Lines were estimated by linear mixed effect (LME) model, according to the equation: Number of wasps foraging = −29.98 + 28.79 × Season + 2.82 × Temperature + Random effect + Residual, where Random effect ~ (0, 23.04) and Residual ~ (0, 28.06). CDS: cold and dry season. HHS: hot and humid season.
