The biology and seasonality of the parasitiod Trioxys pallidus Haliday in western Oregon

Creator:: Cohn, Judy L.
Abstract:: Seasonal synchrony between the filbert aphid, Myzocallis coryli (Goetze) and its newly introduced parasitoid Trioxys pallidus Haliday was examined in the field to evaluate the effectiveness of parasitoid based biological control in filbert orchards of Oregon. Fieldemergence observations showed that 50% eclosion of the aphid occurred 14 days before that...

Toxicity of some commonly used pesticides to Trioxys Pallidus and its establishment in filbert orchards of Willamette Valley

Creator:: Saeed, Mohammad
Abstract:: A parasitic wasp, Trioxys pallidus Haliday (Hymenoptera: Aphidiidae) was imported from Europe and initially released against the filbert aphid Mvzocallis coryli (Goetze) in hazelnut (filbert) orchards of the Willamette Valley, Oregon beginning in 1984. In the present study, I investigated the establishment rates of this parasitoid. A total of 13...

Classical biological control of the filbert aphid, Myzocallis coryli (Goetze) (Homoptera:Aphididae) in western Oregon

Creator:: Messing, Russell H.
Abstract:: A classical biological control project was undertaken against the filbert aphid, Myzocallis coryli (Goetze), in western Oregon. Hazelnut orchards in Spain, France, and Italy were searched for natural enemies of the aphid, and a parasitic wasp, Trioxys pallidus Haliday, was imported, quarantined, mass-reared, and released in Oregon orchards. The wasp...

Structure, function, and analysis of Coleoptera and Heteroptera assemblages on two species of hazelnut in Oregon

Creator:: Wetherill, Karen R.
Abstract:: The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...

The effects of kernel feeding by brown marmorated stink bug (Halyomorpha halys: Hemiptera: Pentatomidae) on commercial hazelnuts (Corylus avellana L.)

Creator:: Hedstrom, Christopher S.
Abstract:: Halyomorpha halys (brown marmorated stink bug, Hemiptera: Pentatomidae), an invasive insect pest, has established populations in the Willamette Valley of Oregon. Halyomorpha halys is a potential pest of many specialty crops in the Willamette Valley, including hazelnuts (Corylus avellana L.). The objectives of this study were to 1) characterize the...

Improvement of biological control agents : laboratory selection for fast larval development in the convergent lady beetle, Hippodamia convergens guerin-Méneville (Coleoptera: Coccinellidae)

Creator:: Rodriguez-Saona, Cesar Ramiro
Abstract:: Hippodamia convergens Guerin-Meneville was selected for rapid development through five generations at four constant temperatures (18, 22, 26, and 30°C). Two levels of selection were used: intense and moderate. Differences in developmental rate, survivorship, live adult weight, aphid consumption, adult longevity, and fecundity were measured for both groups and an...
