A gutsy study of pear psylla (Good Fruit Grower)
Other collaborators include Beers; Dalila Rendon, an Oregon State University postdoctoral associate; and Richard Hilton, an OSU entomologist. They have been sending Cooper samples of psylla from orchards near Wenatchee, Washington; Hood River, Oregon; and Oregon’s Willamette Valley. Each of those areas offer different shelter plants and winter feeding options for the psylla.
