Yellow-Necked Caterpillars in Blueberry
Chatham County, July 2003
Description and Biology of Yellow-necked Caterpillars
Beginning in mid-summer, blueberry bushes should be inspected every two weeks. Clusters of older larvae are usually quite visible feeding on the terminal leaves. Since infestations tend to be localized and readily detected in the field, growers can prevent severe defoliation by pruning out branches with caterpillars.
