Prey-stage preference in phytoseiid mites

Creator:

Blackwood, J. Scott

Abstract:

Knowledge of how individual organisms behave in their environment can provide a greater understanding of population dynamics. In a predator-prey system, the choices made by predators when foraging for prey are important aspects of behavior. Particularly in the case of a stage-structured prey population, how the predator selects prey stages...

Enhancing pest mite biological control by Typhlodromus pyri (Acari: Phytoseiidae) in Pacific Northwest vineyards

Creator:

Gadino, Angela Noelle

Abstract:

The predatory mite Typhlodromus pyri (Acari: Phytoseiidae) is the predominant species in cool climate Pacific Northwest vineyards and a principal predator of pest mites including the grapevine rust mite Calepitrimerus vitis (Acari: Eriophyidae). In recent years vineyards have been experiencing C. vitis population outbreaks leading to increased economic damage from...

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...
