Peshastin Creek Research

Our research in the Peshastin Creek Program falls into two main categories. The primary focus of our work in the valley is monitoring pest populations in the pear orchards. We use these data in combination with data on predatory insect populations, fruit damage and spray costs to compare the effectiveness of three types of pest management programs. These programs range from the more traditional programs of broad-spectrum chemical control through to Organic programs relying on selective compounds and biological control.

The second facet of our research focuses on biological control by native predatory insects.

For background, methods, and general results for both projects, follow the links in the sidebar at right.

Project reports, posters and slide presentations can be found under Research Reports on the main page menu (to left).
