Techniques for field assessment of particulate termite barriers
D M Ewart, E R Rawlinson
Field testing of particulate termite barriers poses problems different from those encountered when testing preservatives or soil termiticides. To ensure an adequate level of challenge, and minimise the risk of a Type II error, the experimental design must promote termite activity and provide a significant, readily detectable, food source which can only be reached by penetrating the test barrier. In this paper we describe the development of techniques for tests with the wholly subterranean Mastotermes darwiniensis and epigeous mound builder Coptotermes acinaciformis and the application of these techniques to explore the particle/building material interface.
