title: [Mollusicidal effects of some species of plants in hilly and mountainous areas].
abstract: OBJECTIVE
  To valuate the mollusicidal effects of some plants cultivated in the hilly and mountainous areas on Oncomelania hupensis and screen the plants against O. hupensis snails.
  
  
  METHODS
  The mollusicidal effects of water extracts of plant materials were tested in laboratory.
  
  
  RESULTS
  The LC50 of all the species in 24 h, 48 h, and 120 h reached the middle noxious level against O. hupensis snails. According to the taxis of LC50(s) in 120 h, Eucalyptus camaldulensis was best with a LC50 of 0.013%, and Ailanthus altissima, Zanthoxylum bungeanum, Juglans regia, Melia azedarach, Nerium indicum, Pterocarva stenobtera, Cinnamomum camphora, Vetiveria zizanioides, and Citrus reticulata were the second with LC50 (s) between 0.020% and 0.370%, and Zingiber officinale had a lower effect on snail control with a LC50 of above 0.500%. There was a correlation between the death rate of snails and soak time.
  
  
  CONCLUSIONS
  The resources of snail-restrained plants are very abundant, and four plants, such as Eucalyptus camaldulensis, Ailanthus altissima, Cinnamomum camphora, and Vetiveria zizanioides have some mollusicidal effect.
