The response to radiant heat and the estimation of the temperature of distant sources in Triatoma infestans

The response of blood-sucking bugs (Triatoma infestans) to thermal stimulation, in the absence of warm-air gradients or convection currents, was analysed, using windows with different infrared transmittance. When some infrared radiation could reach the insects, they responded as without window. When...
