Abstract The purpose of this work was to investigate the potential of ultrasound for inducing chromosomal breaks and aberrations by using salivary glands as material for the in vitro experiment and first instar larvae for the in vivo experiments. Drosophila subobscura, Küsnacht standard/standard strain was used. Ultrasound was applied at 0.3 Wcm−2 at 40 kHz for a period of sixty minutes. Following the in vitro ultrasonication, chromosomal breaks and alterations in the staining by orcein were observed. In the in vivo experiments, the offspring of the treated parents showed inversions and/or transpositions at a frequency of 3 per cent. These aberrations were randomly distributed in the five long chromosomes, and it is noted that none of these inversions was similar to any of the approximately sixty inversions classified for this species (Krimbas & Loukas, 1980).
