Technical Abstract: The Central Ferry research farm is a major site for regenerating seed of germplasm stored at the Western Regional Plant Introduction Station, Pullman, Washington. This station is 60 miles southwest of Pullman along the Snake River in Garfield County. In a typical year, several hundred accessions are increased in nurseries at Central Ferry. It is imperative that these nurseries be protected from insects that might adversely affect plant health and seed production. The Russian wheat aphid first appeared in nurseries in 1988 and entire grass nurseries were sprayed to control damaging populations. The effect of research in 1990 and 1991 to identify Russian wheat aphid-susceptible grass taxa has been more targeted surveys and a more restrictive insecticide control program. In 1988, the Central Ferry station was offered as a release site for exotic natural enemies of Russian wheat aphid, with the result that several thousand parasitoid wasps swere released by APHIS and Washington State University entomologists. Between 1990 and 1998, other research at Central Ferry focused on wheat and wheatgrass resistance to pests, the resistance of fungal endophyte-infected grasses to cereal aphids, and chemical control of insect pests of wheat and canola.
