The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

open access: yesEntomologia 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.

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

open access: yesPest Management Science, Volume 82, Issue 12, Page 11864-11877, December 2026.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...
