Summary.

We identified a tarsal sensillum that has a receptor neurone sensitive to a methanol extract of cabbage root fly eggs. This extract is known to act as an oviposition deterrent. The electrophysiologically active substance in the extract is probably not of host plant origin but a pheromone produced by adult flies.

Key words.Delia radicum (Diptera, Anthomyiidae) – cabbage root fly – oviposition – marking – pheromone – contact chemosensillum
