Preliminary attempts towards the development of a small scale termite rearing chamber. Progress report
1983 - IRG/WP 1203
The results suggest that there is no evidence that the volume of the rearing chamber plays a part in the settlement of a colony. These rearing chambers present a factor of productivity (final enumeration)/(initial enumeration) of roughly 2 after one year. 90% of the colony survived. This method of breeding can be considered as feasible and cheap....

Report of an investigation of damage by wood ants in buildings in Sweden
1976 - IRG/WP 148
Wood ants in buildings occur everywhere in Sweden, particularly in maritime districts and in vicinity of larger lakes. The damage caused by Camponotus herculeanus does not differ from that caused by Camponotus ligniperda. The former occurs in all Sweden, the latter only in southern Sweden. The damage is to be found almost exclusively in dwelling houses (week-end cabins and "all-the-year round" hou...

Report of field test results for dichloro-n-octyl-isothiazolone: A potential new wood preservative
1988 - IRG/WP 3495
In a previous report (IRG/WP/3306) we presented preliminary laboratory test results on 4,5-dichloro-2-n-octyl-4-isothiazolone (RH 287). Laboratory data indicated toxic threshold values for RH 287 ranging from 0.37 to 0.50 kg/m³. In this report we present field test results on an IRG L-joint test and an in-ground stake test for RH 287, pentachlorophenol and biocide free test units. (a) L-joint tes...

Report on marine borer attack on some timbers treated with CCA wood preservative and exposed for three months in sea-water
1985 - IRG/WP 4112
Destruction of timbers by marine borers has long been a problem for the coastal population of Thailand. The use of heavy durable timbers with frequent maintenance, or total replacement, is the only solution for fishermen with their fishing craft or marine installations, meanwhile wharves or other large scale constructions are usually made by using concrete pilings or concrete casings. In recogniti...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water: Final report
1987 - IRG/WP 4133
Three timbers chosen as reference species were treated with 3, 6 and 10% solutions of CCA and CCB preservatives and exposed for up to 93 months at 8 tropical and temperate marine sites. Eleven local species treated in the same way were exposed at 4 of the 8 sites. There was no apparent difference in performance between CCA and CCB treated specimens. The severest test site was Panama Canal but mari...

A direct basidiomycetes test methodology. Report on an EWPM ring test
1988 - IRG/WP 2306
Results of an EWPM-ring test using a direct basidiomycetes test methodology are reported. The test is caracterized by using big test blocks and infestation by infected wood under unsterile conditions. The test procedure needs further development work, but the results are so promising that co-operation with CEN and EHC is initiated with the purpose of recognition and standardization....

Natural Resistance of timbers to marine borer attack. COIPM/IRG CO-OPERATION. Final report concerning panels exposed in the sea at Sekondi, Ghana
1979 - IRG/WP 449
The test was carried out according to Document COIPM/72.044, Revised procedure for the testing of naturally durable timbers against marine borers. The panels of the three species remaining in the test at the end of 1978 were removed and assessed visually. An average rating was given to the panels of each species....

Treatment of messmate (Eucalyptus obliqua L'Hérit) by double-diffusion: Preliminary report
1983 - IRG/WP 3234
Modified double-diffusion is suggested as a method of impregnation for mixed tropical hardwoods for certain types of ground contact use in less developed countries. Compared with vacuum/pressure impregnation, capital costs are low and little skill is needed for the operations involved. Treatment of messmate (Eucalyptus obliqua L'Herit) rounds involving pre-heating in water prior to their ...

Fungus cellar and stake tests with tall oil derivatives. Progress Report after 5 years' testing
1987 - IRG/WP 3442
Two derivatives of tall oils have been tested for five years in fungus cellar and stake tests. The samples were relatively quickly attacked on the surface by decay fungi, mainly soft rot, but the decay has progressed very slowly. The performance of the stakes in the tests has so far been equivalent or even better than some CCA preservatives and creosote....
