1) Investigations have been carried out on populations of nymphs of the tick, Haemaphysalis bispinosa NEUMANN by two collecting methods using cotton-flannel in a pasture at the foot of Mt. Sambe in Shimane Prefecture. One of the two methods was dragging of flannel for some distance and the other was rubbing vegetation on piece of flannel. 2) The same area in the pasture was investigated by both methods at the end of April, 1953. Collecting efficiency of ticks by the rubbing method was much greater than by the dragging method. The regions where many ticks were collected, however, did not necessarily coincide with both methods. 3) It seems that the collecting effciency of ticks by flannel was greatly influenced by temperature in the early spring. Ticks were collected more abundantly in fine than in fine than in cloudy weather, when the maximum temperature in the cluster of grass rises occasionally above 35℃. 4) A laboratory test was conducted on the reaction of nymphal ticks to heat, in which temperature was raised with the rate of 1/4℃. per minute. The test ticks reacted actively to temperatures above 35℃. 5) The rubbing method was used twice in the same area at the end of April and the middle of May, but different results were obtained on the distribution of nymphal ticks.
