Experiments were conducted with six homozygous strains of D. melanogaster belonging to a population from Matsuyama, Ehime Prefecture, in order to examine whether or not a substance(s) secreted by one strain affects the emigration behavior of another strain. From the results of experiments in which flies of one strain in a central tube were discarded and those of another strain were newly introducted, it appeared that in some combinations emigration behavior of the latter strain was influenced by a substance(s) secreted by the former strain. The result suggests that the behavior should be under the genetic control, because the differential responses to the substance secreted by fruit flies were observed among homozygous strains. Bioassay experiments were performed to detect the biologically active substance extracted from adult flies using two strains of the population. The results of bioassay with materials obtained from several steps of separation suggested that the substance may be a kind of fatty acid and different among strains.
