In south central Washington, there are two leafhopper species, the western grape leafhopper Erythroneura elegantula Osborn and the Virginia creeper leafhopper, E. ziczac Walsh (Hemiptera: Cicadellidae), which are pests of wine grapes. In the IPM systems of California, the egg parasitoids Anagrus spp. (Hymenoptera: Mymaridae) provide ample leafhopper control, but in Washington, no real attempt has been made to integrate them with conventional control. Currently, very little is known about the Anagrus spp. in Washington. Using the key by Triapitsyn (1998), at least four species have been identified, including A. erythroneurae, A. daanei, A. atomus and A. tretiakovae. Species of leafhoppers and Anagrus spp. were identified on blackberry, wild rose and grapes and the populations of leafhopper and Anagrus spp. were monitored through the growing season.
