Drywood Termite Control Preliminary laboratory evaluation of chemical local treatments for drywood termites By Dr. Vernard Lewis, University of California, Berkeley, and Dr. Michael Rust, University of California, Riverside Local chemical treatments for the western drywood termite, Incisitermes minor (Hagen), control in California have been conducted by pest management professionals (PMPs) for decades. Some estimates claim as much as 70 percent of the treatments made by PMPs for drywood termite control use local treatments rather than whole-house heat or chemical fumigation. Dozens of products have been registered for termites. Some commonly used products today include Bora-Care® (disodium octaborate tetrahydrate (DOT) 40 percent, Nisus Corp., Rockford, TN), Optigard™ ZT (thiamethoxam 21.5 percent, Syngenta Crop Protection, Inc., Greensboro, NC), Premise Foam® (imidacloprid 0.01 oz/lb, Bayer Environmental Science, East Hawthorn, Vic.), Termidor SC (fipronil 9.1 percent), BASF Corp., Research Triangle Park, NC, Tim-Bor® (DOT) 98 percent, U.S. Borax Inc., Valencia, CA), and XT-2000 (92 percent d-limenone, Formulated Solutions, Woodside, NY). 14 ©Websubstan… | Dreamstime.com Some confusion in the industry and consumers exists over advertising claims of local treatments for drywood termites being equivalent to whole structure treatments using fumigation and heat. For most of the products above, there are gaps in our understanding or no published papers that pertain to California conditions and species of drywood termites. The PMPs’ decision-making process is hampered without reliable efficacy information substantiating product performance claims. Additionally, consumers’ confidence in the PMP may suffer. The Structural Pest Control Board (SPCB) in 2006 and 2007 awarded contracts to the University of California to conduct evaluations on the effectiveness of six commonly used products for drywood termite control. The contracts called for Dr. Michael Rust, Department of Entomology, UC Riverside, to conduct the laboratory component and Dr. Vernard Lewis, Department of Environmental Science, Policy, & Management, UC Berkeley, to direct the field component. Both investigations are currently ongoing; fi nal completion date and reports are due in June 2009. PCOC / SPRING 2009 http://www.Dreamstime.com
