Ten FSE traps baited with a live mouse and ten traps baited with mouse urine were located alternately at more than 20 m intervals along a mountain path in the forest of Ginama, Kunigami Village, in the northern part of Okinawa Island (Fig. 3). Trapping was started on 24 March 1994 and continued until 11 August 1994. The traps were checked for captives every two weeks, when the mouse was tended to and mouse urine was replaced with fresh urine. Nighttime observations of foraging behavior of habus were conducted in an outdoor pen (about 306 m^), where 22 shelters (50xl00x 100 cm) were provided and approximately 30 habus were kept (Fig. 4). The outdoor pen was located at Ozato, Ozato Village, Okinawa, Japan (this facility belongs to the habu study section, Okinawa Prefectural Institute of Health and Environment). In the outdoor pen, eight FSE traps baited with mice had usually been placed to catch habus for laboratory experi- ments. The traps were checked every morning except Sundays. Captured habus were used for bioassay experiments of attractants for about two weeks, and then returned to the outdoor pen after feeding on one to three mice. On 11 August 1994, two FSE habu traps baited with. Fig. 3. Map of the study area at Ginama, Kunigami village, at the northernmost tip of Okinawa Island. Open and closed circles indicate the traps baited with a live mouse and those baited with mouse urine, respectively. mouse urine and two blank traps were placed in the outdoor pen (Fig. 4), and nighttime observations were done using a night viewer betwee
