Larval and Pupal Parasitoids of Diamondback Moth, Plutella xylostella (L.) in Cabbage Fields in Morioka, Japan

Abstract

Seven primary parasitoids, three facultative secondary parasitoids, and seven secondary parasitoids were recorded from larvae and pupae of the diamondback moth Plutella xylostella in cabbage fields in Morioka, North Japan. Among the parasitoids, Cotesia plutellae, Diadegma niponica, Diadromus subtilicornis, and Oomyzus sokolowskii were dominant. O. sokolowskii was the parasitoid of C. plutellae, i.e. the secondary parasitoid of P. xylostella.
