Summary Fluorescence intensity of isolated salivary gland cells of wild-type and arrhythmic (pero)Drosophila melanogaster larvae was measured in constant conditions. The glands were incubated in a medium containing 3.5×10−6M 3,3′-dihexyl-oxacarbocyanine iodide for which cellular concentrations is probably controlled by the membrane potential. In wild-type cells significant rhythmicity of fluorescence intensity was measured over the cytoplasmic as well as the nuclear areas. In pero cells, arrhythmic and rhythmic changes were registered, the latter showing lower amplitudes. We conclude that the decreased amplitude and the lower number of significant cellular rhythms in pero mutants might lead to an apparent arrhythmicity at the behavioural level, i.e. activity and eclosion.
