Parasitoids of Heterogynis Rambur (Lepidoptera: Zygaenoidea, Heterogynidae)

Nine parasitoids of the moth genus Heterogynis are presented: six species of Hymenoptera from the families Chalcididae, Eulophidae and Ichneumonidae (Agrothereutes hospes (Tschek), Baryscapus endemus (Walker), Brachymeria inermis (Fonscolombe), Diplazon laetatorius (F.), Itoplectis maculator (F.) and Trichomalopsis heterogynidis Graham), and three Diptera, family Tachinidae (Compsilura concinnata (Meigen), Exorista segregata (Rondani) and Phryxe hirta (Bigot)). Two of these species, Trichomalopsis heterogynidis and Phryxe hirta, are oligophagous parasitoids specialized on the genus Heterogynis. We also identified two newly recorded parasitoids of Heterogynis: Brachymeria inermis (Chalcididae) and Diplazon laetatorius (Ichneumonidae).

A review of the tachinid parasitoids (Diptera: Tachinidae) of Nearctic Choristoneura species (Lepidoptera: Tortricidae), with keys to adults and puparia

The genus Choristoneura (Lepidoptera: Tortricidae) comprises about 16 species in the Nearctic Region and includes several destructive pests of importance to forestry and agriculture. The following 15 species of Tachinidae (Diptera) are recognized as occasional or common parasitoids of Choristoneura species in this region: Actia diffidens Curran, Actia interrupta Curran, Ceromasia auricaudata Townsend, Compsilura concinnata (Meigen), Cyzenis incrassata (Smith), Eumea caesar (Aldrich), Hemisturmia parva (Bigot), Hyphantrophaga blanda (Osten Sacken), Hyphantrophaga virilis (Aldrich and Webber), Lypha fumipennis Brooks, Madremyia saundersii (Williston), Nemorilla pyste (Walker), Nilea erecta (Coquillett), Phryxe pecosensis (Townsend), and Smidtia fumiferanae (Tothill). Keys to the adults and puparia of these tachinid species are provided. The known distribution, biology, and rates of parasitism are reviewed for each species and published host records from Choristoneura species are listed. Colour habitus images of adults, illustrations of all puparia, and illustrations of features mentioned in the adult key are included. Thirteen other species of Tachinidae recorded from Choristoneura species but excluded from the main text as highly dubious, rare, or accidental records are briefly discussed.
