Nest thermoregulation in Polybia scutellaris (White) (Hymenoptera: Vespidae) Neotropical Entomology
Hozumi,Satoshi; Mateus,Sidnei; Kudô,Kazuyuki; Kuwahara,Takaaki; Yamane,Sôichi; Zucchi,Ronaldo.
Polybia scutellaris (White) builds large nests characterized by numerous spiny projections on the surface. In order to determine whether or not the nest temperature is maintained because of homeothermic conditions of the nest individuals or otherwise, we investigated the thermal conditions within the nests built by P. scutellaris. We measured the temperature within active and abandoned nests. The temperature in the active nest was almost stable at 27°C during data collection, whereas the temperature in the abandoned nest varied with changes in ambient temperature. These results suggest that nest temperature was maintained by the thermogenesis of the individuals of the colony. This is the first report of nest incubation caused by thermogenesis of species of...
