Larvae and pupae of diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were collected weekly for two years on unsprayed cabbage plots. Samples were taken to the laboratory and parasitoids that emerged were identified and their incidence determined. Parasitoids were active throughout the year and parasitism was high (reaching 90-100%) except in the winter months of June-August when it was low.

Twenty one species were reared: the egg-larval parasitoids Chelonus curvimaculatus Cameron and Chelonus sp. (Braconidae); the larval parasitoids Apanteles eriophyes Nixon, Cotesia plutellae (Kurdjumov), Habrobracon brevicornis (Wesmael) (Braconidae) and Peribaea sp. (Tachinidae); the larval-pupal parasitoids Diadegma sp., Itoplectis sp. (Ichneumonidae) and Oomyzus sokolowskii (Kurdjumov) (Eulophidae); the pupal parasitoids Brachymeria sp., Hockeria sp. (Chalcididae), Diadromus collaris Gravenhorst (Ichneumonidae) and Tetrastichus howardi (Olliff) (Eulophidae); and the hyperparasitoids Aphanogmus fijiensis (Ferrière) (Ceraphronidae), Brachymeria sp., Hockeria sp, Proconura sp. (Chalcididae), Mesochorus sp. (Ichneumonidae), Pteromalus sp. (Pteromalidae), Eurytoma sp. (Eurytomidae) and Tetrastichus sp. (Eulophidae).
