Research Project: The Whirligig Mite and New Biological Control Opportunities in Potatoes

Location: Temperate Tree Fruit and Vegetable Research

Project Number: 2092-22000-022-033-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jun 1, 2023
End Date: May 31, 2024

Objective:
Determine the role of whirligig mite in commercial potatoes as source of biological control.

Approach:
USDA-ARS scientists in Wapato, WAc and Washington State University Cooperators in both Wapato, WA and Pasco, WA will describe the phenology of whirligig mite in potatoes by sampling three fields at regular intervals between June and harvest in September. Three sampling tools will be compared, consisting of straw-filled mesh bags, the same bags but with a food supplement, and plant shaking. Prey fed upon by the mite in fields will be examined using molecular methods to detect prey DNA harbored by field-collected mites.
