title: [Study on manufacturing materials of imitation snails].
abstract: OBJECTIVE
  To make imitation snails by using substances with chemotaxis to Schistosoma japonicum miracidia.
  
  
  METHODS
  The imitation snails were made by using Fe3+, gelatin and agar. The modified comparison method of Roberts was used to observe the chemotaxis of imitation snails and snail conditioned water (SCW) to Schistosoma japonicum miracidia.
  
  
  RESULTS
  The mixture consisting of 0.1 or 0.5 mol/L Fe3+, 9% or 10% gelatin, and that consisting of 0.5 mol/L Fe3+, 9% gelatin, 2% or 1% agar could be used to make the imitation snails. The chemotaxis of imitation snails made by the mixtures above was stronger than that of SCW.
  
  
  CONCLUSIONS
  The mixtures made by certain proportion of Fe3+, gelatin or gelatin and agar can be used to make imitation snails.
