title: Electrophysiological responses of the housefly, Musca domestica nebula (Fr), taste receptors to KCl.
abstract: This paper aims at studying the response of the housefly labellar chemoreceptor to stimulation by KCl. These studies are limited to testing various concentrations of KCl solutions (0.005-1 M), using the electrophysiological "tip recording" method and examining the various spike characteristics such as threshold, phasic and tonic response, spike amplitudes, frequency and adaptation; for the anion, cation and water receptors. The large, medium and small hairs all respond to salt. The frontal large, medium and small hairs show a higher frequency response to equimolar KCl than the distal hairs. There is a bilateral symmetry in response pattern. The results are compared with the reported work on Phormia and Calliphora species. The Biedler's hypothesis is also tested for the salt receptors of Musca.
