    The L-type labellar sensilla of homozygous flies show almost no electrophysiological response to either maltotriose, stachyose, raffinose, leucrose or fructose. The response to sucrose, maltose, turanose, maltitol and palatinose is reduced compared to wild type, but not abolished. The response to m-α-glucoside, glucose and melezitose is not reduced in the mutant flies, and the response to glucose may be somewhat elevated.
