Objectives of this study are :1, To clarify effect of steamed larch wood against termite feeding behaviors.2, To clarify chemical structures or constituents of attractants produced by steaming process of wood.3, To use steamed wood for a bait of "bait systems" to prevent termite attacks to wooden houses.4, To investigate the effect of the bait system to remove termite attacks under practical conditions.Results :Item 1 : These investigations were conducted under lab-scale and field tests at Kyuushuu area where is termite infested area. The results showed that steamed larch wood specimens are the best bait for bait systems.Item 2 : The attractants are possibly produced from the main constituents of wood and the products comprised of sugar fractions together with phenolics.Item 3 : This investigation was conducted under lab-scale test and useful results are obtained.Item 4 : This study has been conducted in wooden houses attacked by C.formosanus, and continuously inspected.
