“…Type I parasitism rates have been shown to vary significantly among crown levels for both western (Dodge 1961) and eastern spruce budworms (Jaynes 1954, Miller 1959). Torgersen and others (1984), Waters and Volney (1982 unpubL), and Schmid (1981) generally found no significant differences in parasitism rates among crown levels for either parasite guild. Table 26 summarizes parasitism rates as recorded in the literature for western spruce budworm.…”

In 1977, the United States Department of Agriculture and the Canada Department of the Environment agreed to cooperate in an expanded and accelerated research and development effort, the Canada/United States Spruce Budworms Program (CANUSA), aimed at the spruce budworm in the East and the western spruce budworm in the West. The objective of CANUSA was to design and evaluate strategies for controlling the spruce budworms and managing budworm-susceptible forests, to help forest managers attain their objectives in an economically and environmentally acceptable manner. The work reported in this publication was wholly funded by the Program. This manual is one in a series on the western spruce budworm.

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.
