Entomologia Experimentalis et Applicata, EarlyView.Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.
