Three species of field-margin butterflies are compared with laboratory-cultured Large white Pieris brassicae in their response to insecticides. Four insecticides, spanning a 600-fold range in toxicity, were tested by topical applications to young larvae. The Green-veined white Pieris napi was consistently found to be about half as sensitive as Pieris brassicae. Field tests with Pieris napi and laboratory tests with the Hedge brown Pyronia tithonus and the Common blue Polyommatus icarus supported the selection of Pieris brassicae as an indicator species for bioassay studies of insecticide spray drift.
