Biological control of purple loosestrife Lythrum salicaria (Lythraceae) : stability of control and integration with wetland management practices

Creator:: Schat, Marjolein
Abstract:: Purple loosestrife is a wetland perennial that came to the eastern seaboard of North America in ship ballast and raw wool in the 1800's. Since coming to the United States, it has spread across the country, forming dense monospecific stands in wetlands. Mechanical and chemical control was expensive and ineffective,...

Host selection, reproductive biology, host-specific development and mortality of the codling moth, Cydia pomonella (L.) (Lepidoptera: Torticidae), in apple and pear

Creator:: Marti, Santiago Marti
Abstract:: The biology and behavior of the codling moth, Cydia pomonella (L.), was studied to determine factors responsible for differences in susceptibility to moth damage among apple and pear cultivars. In release experiments, codling moth adults were intercepted in significantly greater numbers in host (apple, pear) than in non-host (maple) trees,...

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...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

Creator:: Morris, Mark A.
Abstract:: Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...
