There are relatively few major insect pests of oilseed rape in Scotland, so when two new pests appear on crops, the reasons for their appearance need to be addressed. Brassica pod midge (Dasineura brassicae) and cabbage stem flea beetle (Psylliodes chrysocephala) have the potential to cause significant damage to Scottish rape crops. In the case of the pod midge, its presence over the last 10 years has not been translated into significant damage. Adult cabbage stem flea beetles suddenly appeared in 2000, but the more damaging larval stage has not been reported at all. The possible reasons for the appearance of these pests in Scotland, whether they are likely to be damaging, and whether they are here to stay is discussed.
