“…Other researchers have also noted that although AE devices work well for termite detection in a laboratory setting, they may be somewhat less effective in field applications (González de la Rosa et al 2015;Lewis et al 2010;Zahid et al 2012). As noted in this study, differentiation of termite activity from other sources of vibration can be difficult in uncontrolled settings.…”

“…A variety of methods used to detect termite activity remotely have been developed, including acoustic emission detection (AE) (LeMaster et al 1997;Fujii et al 1999;Fujii and Yanase 2001;Yanase et al 2003a,b;Mankin and Benshemesh 2006;Osbrink and Cornelius 2013a,b;Green et al 2015;González de la Rosa et al 2015), gas analysis (Khalil et al 1990), radar/microwave detection, LED sensors, moisture sensors, video scopes, and thermal imaging cameras (Lewis et al 2010), to name a few. As part of this research project, several of the technologies that show promise for remote monitoring of bridges were evaluated.…”

“…Radar devices use microwave technology to detect movement of termites (Lewis et al 2010;Le Marshall and Tirkel 2011). At least one device, the multichannel Termatrac T3i handheld detector (Termatrac, Stapylton, Australia), is commercially available (Fig.…”

“…Other researchers have reported that radar is effective in detecting termites in laboratory studies but has been somewhat less effective in field inspections (Le Marshall and Tirkel 2011; Lewis et al 2010;Zahid et al 2012). Detection is limited to a relatively small area and depth within the wood, and readings can be affected by moisture, movement of the device, and vibration within the structure (Le Marshall and Tirkel 2011; Lewis et al 2010). Research continues to develop radar detectors that scan a larger area and produce high-resolution imaging (Le Marshall and Tirkel 2011).…”

The possibility of synergized pyrethrin-containing aerosol as a choice for spot-treating C. brevis in Australia was investigated in laboratory tests. Topical toxicity tests, where C. brevis pseudergates were subjected to multiple doses of pyrethrin mist insecticide, showed the concentration-dependent death of termites with a median lethal dose (LD50) of 193.16 µg. Residual toxicity tests, where the termites were exposed to wood surfaces treated with pyrethrin-containing aerosol, showed a rapid mortality in short and continuous exposures. Less than 20% of the termites survived even when the termites were exposed to a treated wood surface for a minute. All the termites died within 1–5 h in continuous exposure tests, depending on the age of the treated surface. In repellency tests, the termites tended to visit treated surfaces, causing an overall lower survival of the termites. The synergized pyrethrin-containing aerosol remained insufficiently volatile to produce the complete mortality of the termites even after 196 h when there was no contact with a treated surface. The number of termites that survived following the application of the synergized aerosol through a simulated wood gallery or silicon tubing with fecal pellets was also negligible, demonstrating the ability of the aerosol to penetrate through pellets and ultimately resulting in a distribution that is ideal for treatment in the termite galleries.
