Pest index, a new approach to categorizing the threat posed by an organism to woody plants, is proposed to assist plant managers in establishing treatment thresholds for pests of woody plants. The need for such a tool is based on the incredible diversity of pests of woody plants and the lack of experimental data establishing such thresholds. The pest index is computed using information about the detectability, damage potential, and ease of control of various pest groups. Values of the pest index are proposed for a variety of pest groups, but can be readily adapted to other groups not considered (or modified for particular pests that differ significantly from others in the broad groupings listed here). Using the pest index should allow plant managers to deal effectively with pests that are likely to pose serious threats to trees and shrubs instead of simply applying pesticides whenever a pest is detected. Thus, the pest index should foster the adoption of integrated pest management (IPM) in ornamental settings.
