Measuring wood consumption by subterranean termites (Isoptera: Rhinotermitidae) with digitized images
Journal of Economic Entomology 93 (2), 412-414
Abstract: A method is described in which consumption by termites of a feeding block composed of 36 thin (2-mm) wooden slats is estimated with a video image analysis. The significant regression between dry wood weight loss and decreased pixel count of digitized images demonstrates that the video image technique may be a useful tool to quantify termite feeding. Time required to measure wood consumption with the video image technique (~11.5 min per sample) was significantly less than that for the manual method of washing, and weighing wooden blocks damaged by termite feeding (~21.0 min per sample).
