Responses of largest labellar taste hairs of the housefly Musca domestica were investigated with the tip recording technique, Aqueous solutions of KCl and CaCl2 evoke responses in the water and/or the salt receptor cell, The water receptor is progressively inhibited by increasing concentrations of KCI, A concentration as low as 23 mM KCI results in a slight depression (compared to 12 mM KCI), 200 mM and 1 M KCl are needed for 50 and 100% inhibition, respectively. Compared to other fly species the salt receptor activity is relatively weak, The threshold lies around 200 mM KCI and there is no indication of saturation at 3 mM KCI, Therefore it is most likely the water receptor with its graded inhibition which encodes low KCl concentrations. The salt receptor is activated, and the water receptor inhibited by 100 mM CaCl2 in dilute KCI, At comparable receptor activities, the salt receptor displays a shorter latency than the water receptor, The results are compared to data obtained from other fly species. The water and the salt receptor discharge impulses of comparable amplitude and overall shape. The assignment of spikes to the respective receptor types is therefore based on other criteria: regularity of spike trains, latency, susceptivity to CaCl2. Copyright (C) 1996 Elsevier Science Ltd
