Respiration and metabolism of the resting European paper wasp (Polistes dominulus).

ABSTRACT: The European paper wasp, Polistes dominulus Christ, is an abundant wasp species in South and Central Europe which dispersed to the north in recent times. Polistes dominulus exhibits an energy-extensive mode of life, spending much time resting at the nest, which should be reflected in adaptations regarding gas exchange and standard metabolism. We analysed the resting metabolism (CO2 emission) of Polistes dominulus workers in the ambient temperature range an individual may be exposed to during a breeding season (T a = 2.4-40.6 °C) via flow through respirometry. Behaviour and endothermic activity were assessed by infrared thermography. With rising T a, CO2 release followed an exponential increase from 27 to 149 and 802 nl g(-1) min(-1) at T a = 3, 20 and 35 °C, respectively. Measurements of t
