Olfactory sensitivity and locomotor activity was assayed in Drosophila melanogasterstrains carrying a mutation of the flamencogene, which controls transposition of retrotransposon gypsy. A change in olfactory sensitivity was detected. The reaction to the odor of acetic acid was inverted in flies of the mutator strain (MS), which carried the flammutation and active gypsycopies and were characterized by genetic instability. Flies of the genetically unstable strains displayed a lower locomotor activity. The behavioral changes in MS flies can be explained by the pleiotropic effect of the flammutation or by insertion mutations which arise in behavior genes as a result of genome destabilization by gypsy.
