Abstract
Electrophysiological recordings show that the hair-like sensilla on the tip of the labrum in Culex Pipiens L. have neurones that respond to adenine nucleotides. Adenine nucleotides show the following descending order of stimulating effectiveness: ADP > ATP = AMP-PNP = AMP. Sensillar sensitivity to these adenine nucleotides were tested at the concentration range of 10(-5)-10(-3) M. These electrophysiological data are in good accordance with data reported from behavioural studies of this species.
