Assessment of untreated Papua New Guinea timbers against subterranean termites. Progress report 2
1993 - IRG/WP 93-10040
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 ...

An aquaria test of the natural resistance against marine borers of some commercial timbers available in Australia
1996 - IRG/WP 96-10145
The natural resistance of the heartwood of 22 different timbers grown or commercially available in Australia was examined. Radiata pine sapwood both untreated, and treated with 5.4 kg/m³ CCA salt, was included for comparison. Small timber blocks were exposed for one year in tanks containing either Limnoria tripunctata or Lyrodus pedicellatus. Four softwood species tested were heavily attacked and...

Studies on the effect of salinity on the growth and mortality of Teredinids in Papua New Guinea
1977 - IRG/WP 432
Population fluctuations seen in the teredinid species settling in estuarine waters at Marshall Lagoon over a 3 year period were correlated with the salinity fluctuations to which they had been subjected. From these calculations the salinity range in which the most common species settled was determined. Studies in the aquarium were designed to test the salinity range of these teredinids under contr...

Assessment of untreated Papua New Guinean timbers against subterranean termites. Progress Report 1
1990 - IRG/WP 1436
Eight major commercial timber species (Intsia palembanica, Pometia pinnata, Homalium foetidum, Dracontomelon dao, Calophyllum spp., Eucalyptus deglupta, Nothofagus spp., and Alstonia scholaris) were exposed in ground contact against termites. Five replicates of heartwood stakes of 25x25x250 mm³ of each species were randomly embedded in the soil. Results after 24 months exposure showed that Kwila ...
