Susceptibility testing protocol for powderpost beetles in Australia
2002 - IRG/WP 02-20242
Several species of lyctine (powderpost) beetle are able to attack a range of hardwood timbers in Australia. Powderpost beetles infest only the starch-containing sapwood of certain
hardwoods and do not infest softwoods. Attack by powderpost beetles on susceptible timber in Australia is almost inevitable and may continue until the food resource is completely utilised. Prevention of powderpost beetl...

Damage by wood-attacking insects in buildings in Sao Paulo State - Brazil. (including errata slip)
1978 - IRG/WP 175
From 1974 to 1978 up to 602 buildings attacked by wood-boring insects were inspected by Instituto de Pesquisas Tecnologicas in Sao Paulo State - Brazil. Damage was caused mainly by subterranean termites, dry-wood termites and wood-attacking beetles. Up to US $ 1000,000 is the amount needed to control such insects in the buildings inspected...

1980 - IRG/WP 1100
Lyctus brunneus (Steph.) and allied species cause severe damage to wood throughout the world and inflict losses on producers, the trade, industries and craftsmen. Starch-containing wood is liable to attack. The history of the accidental introduction of this wood-destroyer into West-Europe and the causes for this are outlined, biological requirements for the attack as well as developments for Lyctu...

A modified method to determine the toxic values of chemicals against Lyctus africanus (Lesne) by larval transfer method (laboratory method)
2005 - IRG/WP 05-20309
Lyctus africanus (Lesne) is the commonest species widely distributed by trade throughout India. It is one of the most important insect pest attacking logs, branchwood and and practically every kind of manufactured wooden article that contains sapwood. Presently, in India many short rotation and alternate timbers are being used for making many finished products .The inclusion of sapwood containin...

Bemerkungen zu Oligomerus ptilinoides (Wollaston), (Col., Anobiidae): Über Lebensbeziehungen, Merkmale, Verbreitung und Einschleppungen nördlich der Alpe
1978 - IRG/WP 187
Oligomerus ptilinoides occurs in the Mediterranian and Black-sea area, in North-Africa and Asia minor as an important pest causing severe damage to dry wood. By travelling, by the movement of people from south to north, the species tends to establish north the alps. Bad attacks were observed recently in museums. An account is given on taxanomy, the pattern of attack and biological details....

An evaluation of the synthetic pyrethroid cypermethrin in organic solvent and emulsion formulations
1984 - IRG/WP 3290
The studies reported indicate that cypermethrin (NRDC 149) has considerable potential as an insecticide for wood preservatives. Cypermethrin appears to be about twice as effective as permethrin. The effectiveness of cypermethrin compared with g-HCH varies depending on the insect species, the phase of the life cycle and size of larva: for example, against mature Anobium larvae cypermethrin is appro...

Domestic wood preservation - Remedial treatments in Australia
1978 - IRG/WP 3128
Domestic construction in Australia relies heavily upon timber. Because of availability, local conditions and building practices, the timbers and other materials employed vary considerably between the States. In recent years, the timber floor has given way to 'raft construction' (concrete slab-on-ground). Not surprisingly, there is a tendency in each State to use local timbers for...

List of insects intercepted in imported timbers in Italy
1983 - IRG/WP 1217
The list here reported has been derived from an investigation that the Wood Research Institute in Florence has been carrying out for some years, chiefly in sawmills, in order to verify the presence of wood insects in timbers coming from Europe, Africa, Asia, America (North, Central and South). Italy imports a great lot of timbers; during 1980, 1,320,000 m³ of logs and 495,000 m³ of sawnwoods hav...

Wood preservation requirements in Queensland, Australia
1983 - IRG/WP 3227
In Queensland the preservative treatment and utilization of timber must comply with the Timber Users' Protection Act. Preservative retention levels and penetration patterns must be complied with. Analytical zones are specified for removing samples for chemical analysis of preservative retention. The required retention levels have been expressed as percent weight of oven dry wood weight. T...
