CO2 release rates were measured from groups of 10 Reticulitermes virginicus Banks workers, soldiers, and nymphs. For workers, Vĳco2, (μl·mg−1·h−1) increased linearly with temperature between 16.2 - 30.4°C. Vĳco2 recorded at ≈20°C was 0.177 ± 0.005 μl·mg−1·h−1 for soldiers and 0.219 ± 0.027 (μl·mg−1·h−1 tor nymphs. Assuming a similar slope of temperature increase in Vĳco2 for all castes, predicted mass-corrected CO2 release values for grouped R. virginicus workers, soldiers and nymphs at 23.6°C were 27, 52 and 27% lower than literature values for the same castes of R. flavipes measured individually at that temperature. CO2 release rate (μl·mg−1·h−1) for R. virginicus nearly doubled over the 20°C to 30°C temperature range (Q10 = 1.91), similar to literature values for Zootermopsis nevadensis (Hagen) over the same range. For all temperatures except 25.2°C, CO2 release rate (in μl·h−1) increased significantly with mass, with coefficients ranging from 0.123 (16.2°C) to 0.599 (30.4°C).
