Protection for whole-of-house timbers from subterranean termites in Australia
B M Ahmed, J R J French, P Vinden, P Blackwell, J Hann
A field study was designed to increase maximum protection of whole-of-house timbers against subterranean termites. Concrete slab and suspended floor simulated houses were constructed using untreated and treated (slow acting toxicants) timber frames. The treated and untreated timber structures within the simulated houses were exposed with or without soil chemical and/or physical barriers in the field. Although many termite species are known to be present in this field site, the five major economic termite species found attacking either trees, the bait stations or the structural timbers were: Coptotermes spp.; Heterotermes spp., Nasutitermes spp., Schedorhinotermes spp., and Mastotermes spp. The study explores termite foraging behaviour and the termiticidal efficacy of various termite control measures used to prevent termite attack and damage of the simulated houses under natural field conditions.
