About the Cover
Cover: A pair of fruitflies Drosophila melanogaster orienting towards a food source that emits a spectrum of different odorants. Despite the importance of Drosophila as a model organism in olfactory research, few natural odour ligands have so far been reported. On pp. 715-724 M. C. Stensmyr, E. Giordano, A. Balloi, A.-M. Angioy and B. S. Hansson report a number of novel ecologically relevant odour ligands for Drosophila, identified through use of combined gas chromatographic-single receptor neurone recordings. The graph shows the physiological responses of two colocated olfactory receptor neurones to papaya volatiles. The two neurones respond selectively to key components of the papaya blend. Illustration by Marcus Stensmyr.
