Suppressing insect populations and preventing damage by them are integral parts of forest protection and management. We report here a history of the use of various insecticides and the effectiveness of these insecticides against a number of insects in the natural timber stands and plantations of the Eastern Region national forests. Also included are examples of silvicultural and cultural control practices. This report documents the insect species needing treatment, the various treatments used, the suppression results obtained, and the national forests involved.
