Commercial filbert orchards throughout the Willamette Valley were surveyed for natural enemies of the filbert aphid, Myzocallis coryli (Goetze). A large number of predaceous insects were found to prey upon M. coryli, particularly members of the families Coccinellidae, Miridae, Chrysopidae, Hemerobiidae, and Syrphidae. Also, a parasitic Hymenopteran (Mesidiopsis sp.) and...
