Contact chemoreceptors of the antennal segments 115-135 are investigated electrophysiologically. The hairs, of which the external morphology is nearly identical, have an annular arrangement. Although electrical contact can be obtained with the hairs of all but one ring only the sensilla of the ring defined as ring-2 respond to chemical stimulants. Receptor activity, involving greater-than-or-equal-to 2 cells, is elicited by fruit juices, surface and tergal extracts but not by salts, sugars, water, L-alanine and ethanol. The responses of one hair and between hairs of the same antenna to the same stimulant show a considerable variability. Hairs that do not respond possess operating spike generators as can be revealed by electrical stimulation. The role of antennal ring-2 contact chemoreceptors in the context of food and member recognition is discussed.
