title: [Toxicity of 50% ethanol salt powder of niclosamide on growth of silkworms].
abstract: OBJECTIVE
  To observe the toxity of niclosamide on the growth of silkworms.
  
  
  METHODS
  Mulberry leaves were soaked in the different concentrations of solution of 50% ethanol salt powder of niclosamide for 10 s or 3 min, and then the leaves were fed to silkworms. The death rates of silkworms and the weight of cocoons were observed. Normal feeding control groups were established.
  
  
  RESULTS
  The death rates were 22.5%-85.0% and 56.0%-100% in the 10-s-soaked groups and 3-min groups, respectively, which were significantly higher than those in the control groups.
  
  
  CONCLUSIONS
  The 50% ethanol salt powder of niclosamide has a toxity for silkworm. Therefore, we should properly handle the relationship between the Oncomelania snail control and silkworm breeding.
