“…are turfgrass pests throughout North America, whose larvae damage and kill turf by feeding in the stems, roots, and crown of the plant (Dupuy & Ramirez, 2016). About 10 species are known to damage turfgrasses (Vittum et al., 1999), and in the Intermountain West (IMW) region of the United States, bluegrass ( S. parvulus Gyllenhal), hunting ( S. venatus vestitus Chittenden), and Rocky Mountain billbugs ( S. cicatristriatus Fahraeus) make up the species complex that damages the predominantly cool‐season turfgrasses (Dupuy et al., 2017) and are the top insect pest encountered by golf course superintendents (Johnson et al., 2012). Current billbug management strategies include treating turf preventively before adults oviposit, making late‐preventive/early‐curative applications after adults have deposited eggs but before turf damage is evident, or waiting until larvae exit stems and can be found in the soil (often when turf damage becomes evident), then applying late‐curative (or rescue) treatments (Richmond, 2022).…”
