Sparganothis
Sparganothis fruitworm
Sparganothis is a genus of tortricid moths in the subfamily Tortricinae. Several species are significant agricultural pests, particularly of cranberries, blueberries, and grapes. The genus includes the economically important Sparganothis sulfureana, a major cranberry pest in North America, and S. pilleriana, a grape leaf-roller in European vineyards. Species exhibit bivoltine life cycles with larvae that feed on fruit and foliage, causing direct yield losses in commercial production systems.
