Biology, ecology and management of Scaptomyza apicalis Hardy (Diptera : Drosophilidae) on meadowfoam, Limnanthes alba benth in western Oregon

Creator:

Panasahatham, Sarote

Abstract:

Biology of Scaptomyza apicalis Hardy (Diptera: Drosophilidae) was studied in relation to its host, meadowfoam, Limnanthes alba, a recent oil seed crop grown in the Willamette Valley, Oregon. Populations of flies and larvae were monitored weekly over three consecutive crop-years beginning in 1996. Yellow sticky traps gave relative population estimates...

Tactics for enhancing conservation biological control of twospotted spider mites, Tetranychus urticae Koch, in Pacific Northwest hop yards

Creator:

Woods, Joanna L.

Abstract:

The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a worldwide pest of numerous agronomic and horticultural plants. Conservation biological control of this pest can be unreliable due to asynchrony of natural enemies and certain horticultural practices that have a direct or indirect affect on natural enemies and the...

Field and greenhouse studies with Acalymma and Diabrotica : protection of cucurbits with a kaolin-based particle film : feeding damage to cucumbers with and without cucurbitacin

Creator:

Reich, Joel A.

Abstract:

Research was conducted in the field and greenhouse to determine if a kaolinite-based particle film, Surround®, would reduce colonization and early season feeding damage in cucurbits by the Western Striped Cucumber Beetle, Acalymma trivitattum (Mannerheim). Greenhouse studies were designed to determine effect of particle film on cucumber dry weight production...
