Abstract
Studies on the flight habits of D. brassicae indicates that an olfactory stimulus is involved in the migrations. In the present paper the occurrence of olfactory response to rape plants among mated females is demonstrated. The males do not show the same capacity. The odour seems to be perceived mainly by receptors on the antennae. A substance with considerable arresting effect on the females is sinigrin. This substance occurs in the undamaged plant, which indicates that sinigrin is part of a long distance orientation factor facilitating the finding of a suitable host-plant, rather than finding suitable oviposition sites on the plant.
