The fruittree leafroller, Archips argyrospila (Walker), was first observed feeding on baldcypress, Taxodium distichum (L.) Richard, in 1983 in southern Louisiana. Since then, a prolonged epidemic has persisted in semi- and permanently flooded forested wetlands encompassing 100,000 ha. Species and abundance of parasitoids associated with fruittree leafroller on baldcypress were determined at 2 sites in Louisiana during 1994 and 1995. Six species of primary parasitoids were reared from the larvae and pupae of fruittree leafroller. Mortality by all parasitoid species for the combined larval and pupal stages in the 2 seasons was 22.8 and 13.6% at Bayou Pigeon and Norco, respectively. Itoplectis conquisitor (Say) (Hymenoptera: Ichneumonidae) was the most abundant parasitoid and Brachymeria ovata (Say) (Hymenoptera: Chalcidae) ranked second. The rate of parasitism by I. conquisitor for both years averaged 13.8% at Bayou Pigeon and 8.4% at Norco. The eulophid Dimmockia incongrua (Ashmead) (Hymenoptera: Eulophidae) a hyperparasitoid of I. conquisitor. No parasitoids were reared from or found in dissections of egg masses collected in the 2-yr study. Thus, it appears that the absence of egg parasitism and the low levels of larval parasites are responsible in part for allowing populations of the fruittree leafroller to continue at epidemic levels in wetlands in Louisiana. none
