Chemical communication of emigration behavior of Drosophila melanogaster. II. Identification of chemical substances.
Two chemical substances isolated from adult flies of Drosophila melanogaster differently affected the emigration activity of genetically different strains. These substances were identified as palmitic acid and oleic acid, respectively. Chemical and biological comparisons of the natural and authentic compounds showed them to be identical. The behavior response was dependent on the concentration of these fatty acids. The two chemical substances are excreted by adult flies, both male and female, but the emigration activity of one strain was affected by only palmitic acid and that of the other strain, by only oleic acid.
