Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...

Comparison of untreated plywood and untreated LVL in a field trial against Coptotermes acinaciformis and in laboratory trials against Tyromyces palustris and Coniophora puteana
2014 - IRG/WP 14-40671
In Australasia, efficacy data obtained on plywood is generally acceptable for laminated veneer lumber (LVL) and vice versa. This is particularly the case with glueline treatment approvals. The rationale is that the two wood products have predominately the same basic structure with the key difference being orientation of the veneer. LVL typically has all veneers in parallel while plywood typical...
