This study was attempted to develop a rearing method of the tick(Haemaphysalis longicornis) at the laboratory in winter. The rearing conditions for ticks in winter were summarized as follows; Even in the winter, under controlled Incubator on 25~30℃ and 90~95%, temperature and humidity, respectively, it is possible to rear the ticks normally as on summer. in the usual laboratory room temperature and humidity, 20~25℃ and 51 ~77%. In the ticks collected in summer, the life span of the ticks, from hatching to death, was 91～129(112.8±15.2) days in the lagoratory, and the number of the oviposited eggs from a tick were about 1,680~2,460 and the hatching rate of the oviposited eggs was about 95(92~98)%. The life span of the ticks which were reared in the laboratory in winter was 89-138(112.2±21.1) days, and the number of the oviposited eggs from the tick were about 1,382~2,674 and the hatching rate of them was about 89.5(87~92)%. In the rearing of the tick at the laboratory, the dogs, rabbits and mice were able to use the hosts for the tick. The proper temperature to feed the ticks on the cattle in the cold season was obtained by Hokalong/sup ?/ which were attached on the out side of sac which covered bovine ear where attached ticks.
