The seasonal occurrence and distribution of stoneflies (Plecoptera) of a western Oregon stream

Creator:: Kerst, Cary Dean
Abstract:: Plecoptera were collected from four sampling stations selected to represent a range of conditions on Oak Creek, a small woodland stream originating in the foothills of the Oregon Coast Range. The elevation of Site I was 700 ft. while the lowest site was located at 225 ft. Monthly benthos samples...

Organotin resistance in tetranychus urticae koch on pear : components and their integration for resistance management

Creator:: Flexner, J. Lindsey
Abstract:: Reversion of resistance to the organotin (OT) acaricide cyhexatin was documented for the twospotted spider mite, Tetranychus urticae (Koch), by laboratory isolation of a field resistant colony. After 22 generations of no selection the colony reverted back to susceptible. Studies were conducted in 1985 and 1986 on susceptible and resistant...

Culture and nutritional requirements of sod webworms on a meridic diet (Lepidoptera : Pyralidae : Crambinae)

Creator:: Dupnik, Theodore David
Abstract:: Attempts were made to rear Crambus topiarius Zeller, Euchromius ocellus (Haworth), Crambus bonifatellus (Hulst) and Crambus trisectus (Walker) on non-aseptic meridic diets containing wheat germ or pinto beans as basic constituents. Various methods of diet presentation and types of rearing containers were used. Shell vials and plastic cups used as...

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...

Insect community composition and physico-chemical processes in summer-dry streams of Western Oregon

Creator:: Dieterich, Martin
Abstract:: Seven streams, one of them permanent, were studied in western Oregon, USA. The research was designed to assess the value of summer-dry headwaters for conservation oriented landscape management. Streams were categorized primarily according to exposure (forest versus meadow sites) and secondarily according to flow duration (ephemeral = short-flow versus temporary...

Mechanisms of orientation in the leaf-cutter bee Megachile rotundata (Fabricius)

Creator:: Osgood, Charles Edgar
Abstract:: The leaf- cutter bee Megachile rotundata (Fabricius) is an important alfalfa pollinator in western North America. This study was designed to provide information on methods of orientation used by M. rotundata in order to make recommendations regarding the parameters within which adult nesting populations may be relocated. Preliminary studies suggest...

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,...
