The 20 min of training was binned in 2-min periods. The average number of `hot-side' dwellings per fly was calculated based on the number of dwellings and number of flies. The average hot-side dwelling time was calculated and converted to the mean maximum chamber temperature per dwelling with an upper limit of 41°C using the formula: Δ-temp = (time - 0.05612)/0.28114. The formula was derived from data measuring temperature rise times. It fits the data (not shown) with R = 0.99971, P < 0.001.
