Development of contingency plans for use against exotic pests and diseases of trees and timber

Abstract

Summary Factors which may influence the early detection and identification of exotic insect pests of trees and timber in Australia are discussed, with examples from Queensland. Sixty-seven species of wood-boring insects are listed which were intercepted at the Port of Brisbane or detected subsequent to entry during the period 1977 to 1985. The modes of entry and countries of origin of these insects (grouped by families) are presented. Avenues for improving the efficacy of present detection and identification approaches are suggested. The application of stringent quarantine measures at ports of entry is still considered to be our best means of preventing problems with exotic pests in forests and in timber.
