| IPM scouting in stone fruits > green stink bug |
| Feeding injury from green stink bug (GSB) on cherry fruit may cause flesh near the pit to discolor and decay. Feeding injury on peach can take several forms depending on the time of year the injury occurs. Feeding from petal fall through shuck split causes the developing fruit to abort. “Catfacing” (corky, depressed areas of the fruit with small amounts of dried gum in the center) results from feeding at shuck-off until the fruit is approximately 20 mm in diameter. Initial feeding on immature fruit can also appear as small, translucent, blue-green spots that later develop into irregular, depressed areas (dimples). Feeding on mature fruit may appear as little more than a bruise. |
