The effects of exposure of Drosophila subobscura to a 50 Hz magnetic field at different developmental stages on motor activity should be investigated.
Male and female Drosophila subobscura were exposed either as larvae (group 1, egg-first larval stage, n=45/sex) or as just eclosed adults (group 2, n=75/sex). In addition, a cage control group and a sham exposure group were used for each exposure group. Since no differences were observed between these, they were pooled for analysis in one control group (eggs: n=45/sex, adults: n=75/sex).

Both parameters of motor activity, distance travelled and mobility time, were significantly reduced in exposed male and female Drosophila subobscura larvae (group 1) and just eclosed adults (group 2) compared to the respective control groups.
The authors conclude that exposure of Drosophila subobscura to a 50 Hz-magnetic field at different developmental stages might affect motor activity.
