Elimination of snails is one of the important measures for the prevention and control of schistosomiasis. Great achievements have been made in the area of water networks and Pingba by eliminating snails and actively treating humans and animals. However, in sparsely populated areas in the mountainous areas, the terrain is complex, the traffic is blocked, the snail area is large , Less labor, snail breeding complex environment.Moving method is also limited, requiring the elimination of all snails to eliminate the purpose of the elimination of mountain schistosomiasis, it is difficult to achieve, therefore, to understand the characteristics of mountain snails infective infection, targeted to carry out Lo snail work
