Experimental setup used to record the biting responses of G. pallidipes (not to scale). A acclimatisation airflow (the grey triangle symbolizes the funnel), B test airflow, C water-bath to control the temperature of the acclimatisation airflow, D apparatus to control the relative humidity and the temperature of the test airflow, E chain of power LEDs covered with opaque Plexiglas as background light, F chain of power LEDs to illuminate the underside of the cage, G red LED switched on by contact when the cage is in place on the test flow, H suspended cage, I reflective paper (grey colour), J, K, L thermistor probes measuring the ambient, acclimatisation and test airflow temperatures, the hygrometer M measuring the relative humidity of the test airflow and the anemometer N, O drawing of the insect cage in mm with a nylon mesh at the top of the inner tube and mosquito netting at the bottom of the outer tube. H, I, J and N were mounted on a sliding mechanism that allowed movement of the insect cage from the acclimatisation airflow to the test airflow.
