Natural enemies
An egg parasite, Anagrus epos, is commonly present during part of the season in many vineyards, especially
vines adjacent to prune, plum, or almond trees. After a leafhopper egg is parasitized, it becomes visibly
red. Unfortunately, this parasite is not as effective on variegated leafhopper eggs as it is on those
of the grape leafhopper.
The large predaceous mite, Anystis agilis, attacks
grape leafhopper nymphs. Other predators of leafhoppers include
green lacewings, minute
pirate bugs, lady
beetles, bigeyed
bugs, and spiders.
