title: [Cost-effectiveness analysis of mechanical and manual soil-buried methods for Oncomelania hupensis control].
abstract: OBJECTIVE
  To explore a high molluscicidal efficient method in special Oncomelania hupensis snail environments.
  
  
  METHODS
  In 2005 and 2006, in large special environments (rubble creek beaches and seepage barren hills with snails), the mechanical soil-buried method (excavator digging to bury deep snails) and manual soil-buried method were used respectively, and the results were compared for the cost-effectiveness.
  
  
  RESULTS
  With the mechanical soil-buried method in 2006, the investment was 0.78 yuan/m2, and the compression rate of snail areas was 100%; with the manual soil-buried method in 2005, the investment was 1.34 yuan/m2, and the compression rate of snail areas was 20.26%. The former was much better than the latter.
  
  
  CONCLUSIONS
  In the large special environments with snails, the mechanical soil-buried method is superior to manual soil-buried method.
