Abstract

Ecological Applications Building laboratory bioassay chemassay field bioassay Plasmite Reticulation system geotextile simulated wall cavity bifenthrin Coptotermes acinaciformis lethal penetration threshold
Laboratory and field bioassays undertaken to demonstrate Plasmite Reticulation system effectively delivers the termiticide (bifenthrin) within a simulated wall cavity at the required concentration. The chemical assay indicated that the amount of bifenthrin sampled at 5, 10, 15, 20, and 25m along the simulated reticulation system tested (30m) exceeded the manufacturer's minimum recommendation of 0.0044%m/m. Results of the laboratory bioassay, using Coptotermes acinaciformis, indicated that the concentrations of bifenthrin present in the soil core samples at 5, 10, 15, 20, and 25m were extremely toxic and prevented termite penetration of bifenthrin treated soil in laboratory bioassays immediately after field soil treatment. No penetration of any soil core samples was observed in the field test against Coptotermes lacteus.
