Abstract: Ili Pika (Ochotona iliensis Li et Ma, 1986) is a new species which distributed over the Marmota baibacina Plague Natural Foci of the Tainshan Mountains in Xinjiang. This paper reported the preliminary study about its ecology and relationship with the plagae natural foci. Oar observitions showed that this species was distrbuted all over the plague natural foci of the North Tainshan Mountaia in 8 counties and its habitat had some relation to that of the main reservoir on the high part of the foci. However, according to this Pika's ecological characteristics and the resales of zoonosis investigations, the possibility that it served as main reservoir in the foci was ruled out.
