124: Virginia Creeper Leaf Hopper in Vineyards

While many growers are familiar with the Western Leafhopper, they may not know as much about the Virginia Creeper Leafhopper. Houston Wilson, Assistant Cooperative Extension Specialist in the Department of Entomology at UC Riverside and Director of UC Organic Agriculture Institute has been studying the Virginia Creeper Leafhopper and potential biological controls.

Leafhoppers are pierce and suck feeders. The insect removes small amounts of plant material causing a stippling effect on the leaf. This damage reduces the photosynthetic capacity of the vine and can reduce yields.

The Virginia Creeper Leafhopper was recently introduced into the North Coast of California where it was discovered that it has no biological controls. Additionally, its life stages are different from the more well-known Western Leafhopper so growers must utilize different management practices to control the pest.
