The station is 60 miles southwest of Pullman and is located along the SnakeRiver in Garfield County. In a typical year, several hundred accessions are increased innurseries at Central Ferry. It is imperative that these nurseries be protected from insectsthat might adversely affect plant health and seed production. The Russian wheat aphid(RWA) first appeared in Central Ferry nurseries in 1988, one year after it was firstdetected in eastern Washington. Entire grass nurseries were sprayed in 1988 and 1989 tocontrol damaging RWA populations. The effect of research in 1990 and 1991 to identifyRWA-susceptible grass taxa has been more targeted surveys and a more restrictivechemical control program. In 1988, the Central Ferry station was offered as a release sitefor exotic natural enemies of the RWA, with the result that Washington State Universityand APHIS entomologists released several thousand hymenopterous parasitoids at thesite. In the last seven years, replicated field plots have been established to study: 1) theresistance of fungal endophyte-infected grasses to cereal aphids (S.L. Clement), 2) theresistance of spring wheat lines to RWA and Hessian fly (D.E. Bragg, N. Bosque-Perez,S.L. Clement), 3) the chemical control of cereal aphids and Hessian fly with new-generation insecticides (D.E. Bragg), 4) chemical control of canola insect pests (D.E.Bragg), and 5) the susceptibility ofwheatgrasses to Hessian fly (S.L. Clement).61
