Year: 1987
Type: article
Abstract: The diamondback moth, Plutella xylostella L. is the most serious insect pest of cruciferous crops such as cabbage, broccoli and radish in Miyazaki. Larvae and pupae of P. xylosiella were collected to examine their natural enemies in 1985 and 1986. The ichneumonid Diadromus collaris, the braconid Apanteles plutellae and the eulophid Tetrastichus sokolowskii were dominant parasitoids. Four other parasitic wasps were also observed, but they accounted for only 2% of all the parasitoids. D. collaris appeared from April to October, and a percentage parasitism of 50 to 60% was recorded in the samples collected in June and July. A. plutellae emerged throughout the season and the percentage parasitism of this wasp ranged from 20 to 60% in samples collected during June to November. Although the percentage parasitism of T. sokolowskii was rather low in spring to early summer values of 50 to 80% were recorded in the samples collected inautumn.
