Extract

The zebra caterpillar, Melanchra picta (Harris), has been reported as a minor pest of corn (Philip 1990) and some small fruits (Belton 1988; Fitzpatrick and Troubridge 1991) in British Columbia. This pest also infests various vegetables, blueberries, and currants, and has become more and more abundant lately in the Fraser Valley (unpublished data). The larval parasitoid Limneria annulipes Harris (Hymenoptera: Ichneumonidae) has been reported to parasitize zebra caterpillar populations in eastern Canada (Maxson 1948). Fitzpatrick (pers. comm.) found Winthemia quadripustulata (Fab.) (Hymenoptera: Tachinidae) from zebra caterpillars in British Columbia. Here we report the occurrence of another larval parasitoid reared from natural populations of M. picta collected from commercial high bush blueberry fields in Delta, British Columbia, during June of 1992.
