Fig. 4. Examples of the respiratory pattern of a female mosquito at 20°C. The same female was measured at flow rates F=100 (A), 50 (C) and 20 ml min^–1 (E). The respiratory pattern of this same female at F=1000 ml min^–1 is shown in Fig. 2A. (B,D,F) Values produced by mathematically manipulating the values from Fig. 2A to mimic the patterns in A,C,E, respectively. Data were manipulated by multiplying by 10 and using a sliding average of 7 (B), multiplying by 20 and using a sliding average of 15 (D) and multiplying by 50 and using a sliding average of 35 (F).
