Braconid parasitoids (Hymenoptera: Braconidae) of NearcticChoristoneuraspecies (Lepidoptera: Tortricidae), with a summary of other parasitoid families attackingChoristoneura

Abstract

AbstractIllustrated identification keys are given for the superfamilies/families of insect parasitoids and the subfamilies, genera, and species of Braconidae reared from species ofChoristoneuraLederer in the Nearctic Region.Goniozus floridanus(Ashmead) (Chrysidoidea: Bethylidae) represents the third superfamily of Hymenoptera, andColpoclypeus florus(Walker) (Hymenoptera: Eulophidae) is added to the list of Chalcidoidea recorded fromChoristoneura. Fifty species of Braconidae in 18 genera and 9 subfamilies are recorded parasitizing 11Choristoneuraspecies; almost half belong to the Microgastrinae. Eight braconids (16%) were found for the first time as parasitoids ofChoristoneura. The first host record is given forOncophanes californicus(Ashmead) (Hormiinae). Known insect parasitoids ofChoristoneuraspp. in the Nearctic Region include 230 species in 106 genera, about 75% of which attack only 1 or 2Choristoneuraspecies each. An additional 36 species are considered incorrectly associated withChoristoneura, an error rate of 14%. The Banchinae (Ichneumonidae, especiallyGlyptaGravenhorst), Pimplinae (Ichneumonidae), and Microgastrinae (Braconidae) made up the greatest proportion of parasitoids. No parasitoids have yet been recorded from five NearcticChoristoneuraspecies.
