Abstract


Anagrus daanei S. Triapitsyn, A. erythroneurae S. Trjapitzin and Chiappini, and A. frettakovae S. Triapitsyn parasitize Western grape leafllopper, Erythroneura elegantula Osborn, and Virginia creeper leafhopper, E. ziczac Walsh, eggs during the summer. These leafhoppers overwinter as adults and Anagrus overwinter in leafhopper eggs. Thus, Anagrus must find other leafhopper eggs in which to overwinter. To identify plants on which these parasitoids and their host eggs overwinter, we collected 31 species of plants from 52 sites in the grape growing region of south central Washington and north central Oregon during the winter from 2000 to 2007. A total of 733 female and 1066 male Anagrus was reared from the plants. Twelve plant species harboured Anagrus spp. during the winter. Anagrus erythroneurae was reared from blackberry, Rubus armeniacus Focke; willow, Salix spp.; Wood’s rose, Rosa woodsii Lindley; sweetbrier rose, R. eglanteria L.; rugose rose, R. rugosa Thunberg; and ornamental roses, Rosa spp. L. Anagrus tretiakovae was found on choke cherry, Prunus virginiana L.; rugose rose; Rosa spp.; and blackberry. Only one specimen, from omamental rose, was tentatively identified as A. daanei. Other specimens were identified as A. atomus L., A. avalae Soyka, A. nr. sp. avalae, A. nr. sp. columbi Perkins, A. nigriventris Girault, and A. nr. sp. nigriventris.
