The main objective of this study was to determine the potential parasitoids of Plutella xylostella and assess their parasitism level in relation to cabbage cultivar. Studies concerning population dynamics of primary parasitoids, percent parasitism of parasitoids and interaction of P. xylostella in relation with cabbage cultivar carried out in two areas namely Mansehra and Taxila during 2011-12. During autumn 2011, the maximum population of P. xylostella (54 individuals/plant) was recorded at an average minimum (10.9°C) and maximum (25.8°C) temperatures, with 75% relative humidity at Taxila site. Among them larval parasitoid species i.e. Diadegma insulare (Ichneumonidae) was solitary parasitoid. O. sokolowskii (Eulophidae) was a gregarious parasitoid which attack both in larval and pupal stages whereas Diadromus collaris (Ichneumonidae) was found to be pupal parasitoid. The maximum parasitism (40%) was recorded in case of D. insulare in the spring season, followed by 19.2% parasitism in case of O. sokolowskii in autumn season and maximum parasitism recorded in case of D. Collaris was 8.0% in the spring season at Taxila site.
