Eight species of Papua New Guinea wood including Kwila (Intsia palembanica), Taun (Pometia pinnata), Malas (Homalium foetidum), PNG Walnut (Dracontomelon dao), Calophyllum (Calophyllum sp.), Kamarere (Eucalyptus deglupta), PNG Beech (Nothofagus spp.) and White Cheesewood (Alstonia scholaris) were exposed groun contact for their natural durability against subterranean termites. Inspection after 42 months showed that Kwila was still sound while Taun, Malas and PNG Walnut had minor attacks after the last inspection. The termites found attacking the stakes were Coptotermes obiratus, Microcerotermes repugnans and Nasutitermes novarum hebridarum.
