Which statement best describes how chinch bug infestation is detected in warm-season turf?

• A. Old signs appear and not visible on blades.
• B. Uniform color indicates infestation.
• C. Detection relies on root sampling.
• D. Yellowing and wilting with visible insects on blades or in sheltered leaf areas.

Answer: (D)

Chinch bugs are sap-sucking insects that attack turf from the leaf canopy, so you detect them by above-ground signs and by spotting the bugs where they congregate on the blades or in sheltered leaf areas. In warm-season grasses, infested patches show yellowing and wilting, especially during hot, dry conditions, and you can often see the insects on the blades or tucked into leaf sheaths and other protected spots. This combination of symptoms plus the visible insects confirms an infestation. Root sampling isn’t a reliable method for detecting chinch bugs because the damage is above the soil surface, not primarily in the roots, and uniform color is not typical since the damage tends to be patchy where bugs are concentrated.
