Management Information Integrated management: Henin and Paiva (2004) state that, "Management of bark beetle populations, such as O. erosus can only be achieved by adopting an integrated approach. Among preventive measures, this approach must combine ''prophylactic'' silviculture practices with an enhancement of their natural enemies, some of which have been shown to exert a significant impact upon bark beetle populations." Chemical: In field experiments, Klimetzek and Vite (1986) were able to lure O. erosus into traps baited with a combination of the beetle produced compounds 2-methyl-3-buten-2-ol and ipsdienol. The authors state that, "When offered along with 2-methyl-3-buten-2-ol, an up to 1000-fold increase in concentration of racemic ipsdienol led to a continual increase in catch of O. erosus and Ips sexdentatus, accompanied by a steady increase of .female..female.-%. It is assumed that 2-methyl-3-buten-2-ol influences landing behaviour of O. erosus, while ipsdienol acts as a long distance signal". Mechanical: In South Africa, Wylie (2000) reports that, "Sanitation felling and removal of Rhizina-infected older trees is necessary to prevent build-up of O. erosus. Biologcial: Tribe and Kfir (2001) have been studying Dendrosoter caenopachoides, which was introduced into South Africa for the biological control of O. erosus.          Management Resources/Links 1.
