Abstract/Contents: | "Six species of cereal aphids infested field plots of perennial grass accessions of Festuca arundinacea Schreb. (tall fescue), Agropyron desertorum (Fisch. ex Link) Schultes (standard crested wheatgrass), and Dactylis glomerata L. (orchard grass) at Pullman and Central Ferry, Wash., in summer 1988. Seed of cool-season perennial grass accessions from the United States germplasm collection is routinely increased at Pullman and Central Ferry, Wash. Russian wheat aphid, Diuraphis noxia (Mordvilko) (Homoptera: Aphididae), assumed dominant status at Central Ferry and English grain aphid, Macrosiphum avenae (F.), was dominant at Pullman. Other species found were Metopolophium dirhodum (Walker), greenbug, Schizaphis graminum (Rondani), bird cherry-oat aphid, Rhopalosiphum padi (L.) and Sipha elegans del Guercio. Overall, aphid densities were highest in nonirrigated plots at Pullman (x aphids/five tillers = 191.87), intermediate in irrigated plots at Central Ferry (x=47.86), and lowest in nonirrigated plots at Central Ferry (x=15.70). At Central Ferry, significantly fewer (P < 0.05) aphids were recovered from F. arundinacea, than from A. desertorum and D. glomerata; however, aphid densities were higher on F. arundinacea at Pullman. Results indicate that cereal aphids pose a potential hazard to seed regeneration and should be monitored to ensure against loss of grass germplasm. Also, results show that some commonly occurring Pacific Northwest perennial grasses have the potential to support natural populations of the Russian wheat aphid." |
