Development of contingency plans for use against exotic pests and diseases of trees and timber. 3. Histories of control measures against some introduced pests and diseases of forests and forest products in Australia.
Responses by quarantine and forestry authorities to the inadvertent introduction to Australia of 7 economically important pests and pathogens of forest trees or forest products from the time of introduction to the present are described. Eradication was achieved only in the case of Hylotrupes bajulus, but not for Cryptotermes brevis, Ips grandicollis, Sirex noctilio, Melampsora medusae, M. larici-populina and Dothistroma septospora [Mycosphaerella pini]. It is argued that the Australian Agricultural Health and Quarantine Service should be actively involved in control campaigns until effective pest or disease management strategies have been developed.
