Six wood products used in wall paneling were tested for resistance to feeding damage by the eastern subterranean termite, Reticulitermes jZuuipes (Kollar). Alaska-cedar, Cha~naecyparis nootkatensis (D. Don) Spach, fiber without wax and resin treatments normally used in paneling production was not a preferred food source in choice tests where all 6 wood products plus pine, Pinus palustti Mill., were simultaneously provided. However, the same nontreated Alaska-cedar fiber sustained severe damage when provided as the only food source in no-choice tests. Nontreated fiber of western hemlock, Tsugu heterophyllu (Raf.) Sarg., and hardboard and hardboard paneling made from a mixture of western hemlock and Douglas-fir, Pseudotsugu menziesii (Mirb.) France, sustained significant feeding damage in both choice and no-choice feeding tests. Pressed paneling mats made from Alaska-cedar or western hemlock exhibited antifeedant properties. Waxes, resins, and additives used in manufacturing these mats imparted resistance to R. fEauipes.

Of the two haplotypes identified in Mississippi, the GA group was identical to those reported previously in Georgia, Louisiana, Alabama and other infested states. The second haplotype, the AT group, was identified for the first time in southeastern United States. Sequence identity of the AT-group C. formosanus with those reported mainly in southeastern Asian countries provided evidence of at least two introductions of C. formosanus into the United States.
