Adults and nymphs of several species of grasshopper feed on grape leaves, usually beginning in late summer when preferred hosts begin to dry up. Feeding by these well-known, long-legged jumping insects consists of chewing damage to leaf margins, most often on lower leaves.
Grasshoppers suffer from pathogenic diseases when populations are high.
Preying mantids, toads and many species of birds feed on adults, while smaller nymphs are attacked by spiders and a number of predatory insects such as ground beetles.
Maintaining the growth of drive row vegetation, particularly broadleaf plants, over the season reduces feeding damage to grapes.
Grasshoppers will be affected by most sprays directed against other pests of grapes.
