Description

In order to understand the fluctuation in cattle tick ( Haemaphysalis longicomis) population density in Japanese grazing lands, we investigated tick density in sown and indigenous pasture in North East Japan from 1979 to 1984. It became clear that the life span of grazing cattle is longer in sown than in indigenous pasture. Nevertheless, cattle tick density is lower in sown pasture than in indigenous pasture. It appears that the grazing cattle have not only the role of host but also contribute to cattle tick mortality. We proved experimentally that a great number of ticks are eaten by the grazing cattle. In a sown pasture the proportion of ticks eaten is by far larger than the proportion finding and attaching to a host. It is clear that grazing cattle are indispensable for the ticks, providing hosts and simultaneously cattle act as a tick predator.
