The present investigation was to survey the habitat of Cigaret beetles indoors and outdoors by pheromone and bait traps. The same six houses and six apartments within Tokyo and neighboring prefectures (Kanagawa and Chiba) as in the first report (KAWAKAMI and NAKANO, 1996) were used. The first investigation with pheromone traps was conducted from 15-31, August, 1996. Two houses and two apartments were used 15, September to 1, October ; 15-31, October 15, November to 1, December, 1996. The pheromone traps were set in a kitchen, Japanese-style room, foreign-style room and outside veranda. The two houses within Tokyo were used for the bait trap study (catch alive) conducted from 15-31, August (I's house) and from 15-24, August (N's house), 1996. The bait traps were set on outside verandas. One pheromone trap was placed in front of a house, one under a bridge-style promenade of a neighboring apartment, one in front of a roofed parking lot at Shiba public health center and one unber a bench or telephone box in Odaibakaihin park at Minato-ku, Tokyo. Investigation was carried out in the middle of the month (about 10 days), August, 1996. Three bait traps were placed under a bridge- style promenade of a neighboring apartment at Minato-ku, Tokyo from 15-24 and 24-31, August, 1996. All pheromone traps (twelve houses) caught Cigaret beetles.The largest capture number was in August, and the largest capture number per house was 882, the smallest number, 68 and average, 266. The capture number of Cigaret beetles was increased within Tokyo more than in neighboring prefectures and higher for outside verandas. Most outdoor pheromone traps caught Cigaret beetles. The largest number was at the bridge- style promenade of a neighboring apartment. In outdoor investigation of outside veranda as and neighboring apartments all bait traps caught Cigaret beetles. The capture number per outside veranda was 13 (I's house) and 25 (N's house) and average of a neighboring apartment, 23 (8/15-24) and 21 (8/24-31). Adult emergence of a subsequent generation (adults was 26-52) from bait traps was 40 to 50 days after retrieval. Cigaret beetles thus appear to eat many vegetables outdoors, and oviposition to occur on a withered leaf, dry grass and others at outdoors in summer. The results of the last time and this investigations suggest Cigaret beetles to likely lead ordinary lives in houses, and keep their life cycle by going outdoors (summer) and coming back indoors (late autumn), and utilize building materials for survival.
