Laboratory and Field Studies on Subterranean Termites Native to the Eastern United States

Little, Nathan Shook 01 May 2010 (has links)
This study investigates modifications to AWPA Standard E18-06 to develop an above-ground field test for subterranean termites native to the eastern United States. AWPA Standard E18-06 was modified in two stages to progressively increase optimum conditions for subterranean termite feeding. Modification II, which incorporated the use of house bricks and feeder strips with a solid ventilated cover, had an increase in termite attack with less variation between tests. This study also investigates the effects of adding antioxidants, both natural and synthetic, and analogues which lack antioxidant properties, to test wood blocks on feeding by Reticulitermes flavipes Kollar using AWPA Standard E1-09. Antioxidants had feeding deterrence and mortality properties to R. flavipes. Conversely, the non-antioxidant analogues, with the exception of the heterocyclic flavanone, had little effect on R. flavipes. It is concluded that R. flavipes instinctively avoids wood which contains high levels of antioxidants, such as heartwood with phenolic extractives.

Evaluation of Parameters Specified in AWPA standard E1-97: Standard Method for Laboratory Evaluation to Determine Resistance to Subterranean Termites

Lindsey, Gary Brian 01 May 2010 (has links)
This research focuses on the evaluation of many aspects of the American Wood Protection Association (AWPA) Standard E1-97, “Standard Method for Laboratory Evaluation to Determine Resistance to Subterranean Termites.” This standard is used extensively for testing the efficacy of new products and preservative systems against subterranean termite species. Research was done to determine what changes, if any, are needed for testing against subterranean termite species such as Coptotermes formosanus (Shiraki) and species of native termite genus Reticulitermes (Holmgren), primarily R. flavipes (Kollar). Variables from the current standard were tested to determine effects of parameters such as moisture of sand substrate; size, type, and location of test material within a test bottle; and termite number and ratios of workers to soldiers per test bottle. Research also improved comprehension of termite biology in a laboratory setting, enabling researchers to develop new and safer control methods.
