The characteristic sound frequency, maximum spike response, spontaneous activity and rate of adaptation of individual auditory receptors in locusts increase as the ambient temperature increases. For changes in the ambient temperature between 22 degrees C and 32 degrees C the characteristic frequency shifted by 0.1 to 0.2 octaves per degree centrigrade with an average thermal Q10 of 2.93 and the maximum rate of production of action potentials of individual receptors doubled. These effects exceed those expected from temperature dependent changes in mechanical properties of the tympanic membrane or the auditory organ. It is therefore concluded that the receptors contain a temperature dependent cellular process that contributes to the tuning of the sensilla.
