Influence of pheromone trap (New Serrico[R!○]) location on the capture of cigarette beetle, Lasioderma serricorne, was studied in the feed processing plant in Shizuoka Prefecture, Japan in 2003. Traps on the walls captui ed more beetles than traps apart from the wall. Traps on the 'web' of H-shape steel captured more beetles than 'flange'. But this result was not based on the difference between structure of 'web' and 'flange'. Because the areas of 'web' were larger than those of 'flange', and the number of beetles captured was not significantly different between traps placed on imitation models of 'web' and 'flange' made by same area (1,680 cm^2) cardboards. Thus, it was indicated that the pheromone traps placed on the wide flat area could capture more beetles than the trap located in space or on the smaller flat area, and this may be explained by the behavior of the cigarette beetle: it approaches the pheromone trap by flying and makes landing near the trap, and after landing it enters to the trap by crawling.
