Tag hinzufügen | Zusammenfassung: | Dissertation, Friedrich-Schiller-Universität Jena, 2013 Geosmin is produced by a group of microbes, is highly aversive to Drosophila. We furthermore showed that Drosophila has one type of sensory neurons expressing an odorant receptor (OR 56a) that is extremely sensitive and fully dedicated to detect this compound. The Geosmin detection System is conserved across the genus Drosophila. Exploiting aversivespecific circuits could be an efficient method for manipulating disease vectors as well as agricultural pests. Next I showed that flies exhibit increased attraction to ethyl acetate, to another food odor, even to a repellent and pheromone after starvation. All odors evoked stronger physiological responses in starved flies with the effects being most pronounced at low odor concentrations. ... |
