 note = {(1) The ecological characteristics of the tick (H. bispinosa) in the farm of Kiyosato Educational Experimental Project (KEEP) were investigated from May 1966 to May 1967. (2) The investigated areas is sloping at about 10° degree and acidic soils. Bush, sown pasture and pasture are found in this area which are different from each other in climatic conditions. (3) Frannel and rabbit methods were used to capture ticks. (4) As the result, the following facts were found: i. The habitat of the tick is the shade and humid places with tall grasses such as sedge, Japanese pampas grass and bamboo grass, which provide with water places or rest places for grazing cattle. ii. The period of multiplication is mainly in summer (Fig. 16). iii. The tick is found throughout the almost whole area in summer, but it is restricted to some particular blocks in' autumn (Fig. 16). In bush zones, especially the block 8-B, the density of the tick was highest, where 3848 individuals were captured from one rabbit. The main factor of controlling tick's dispersal is grazing cattle. Although it is presumed that the dispersal of ticks are also caused by the small and middle mammals, especially wild mice such as Apodemus speciosus or Microtus montebelli, they were not available for transporting factors in the present area., Article, 信州大学教養部紀要. 第二部, 自然科学 2: 17-42(1968)},
