Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

Survival and development of the flat-headed fir borer in forest residues as affected by host and microclimatic conditions

Creator:: Scott, Donald Wayne
Abstract:: The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...

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...

Management of variegated cutworm in peppermint

Creator:: Coop, Leonard Bryan
Abstract:: A pest management program for variegated cutworm (VC), Peridroma saucia (Hubner), in Oregon peppermint was developed based on studies of pheromone trapping, sampling methods, and economic thresholds. Pheromone traps effectively trapped VC males and were used to reflect development and oviposition trends. Trap height was linearly correlated to moth catch...

Regional population dynamics of Argyrotaenia citrana in Northwest caneberry : phenology, overwintering survivorship, and movement as measured by pheromone traps and larval sampling

Creator:: Knight, Alan Lee
Abstract:: Developmental requirements were determined for both larva and pupa as 503 and 176 degree-days (dd) above a lower threshold of 5°C. Adult emergence occurred from 300 to 700 dd accumulated from January 1st. Cumulative male emergence preceded female's by 50 - 80 dd. A PETE phenology model modified to include...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

The leafhopper genus Tiaja Oman (Homoptera:Cicadellidae), with a contribution to the biosystematics of the group

Creator:: Sawbridge, Jane Rosamund
Abstract:: The genus Tiaja Oman consists of eight known species of flightless leafhoppers of the subfamily Megophthalminae found along the western coast of North America between British Columbia and northern Mexico. Species occurring from the San Francisco Bay area northward are restricted to a narrow coastal zone within 1 km of...
