摘要：

Six species of cereal aphids infested field plots of perennial grass accessions of Festuca arundinacea (tall fescue), Agropyron desertorum (standard crested wheatgrass) and Dactylis glomerata (orchard grass) at Pullman and Central Ferry, Wash., in summer 1988. Russian wheat aphid Diuraphis noxia assumed dominant status at Central Ferry and English grain aphid Macrosiphum avenae was dominant at Pullman. Other species found were Metopolophium dirhodum, green-bug Schizaphis graminum, bird cherry-oat aphid Rhopalosiphum padi and Sipha elegans. Overall, aphid densities were highest in nonirrigated plots at Pullman (mean aphids/five tillers - 191.87), intermediate in irrigated plots at Central Ferry (47.86), and lowest in nonirrigated plots at Central Ferry (15.70). -from Authors
