Molluscicidal activities of Tribromosalan, Cartap and Chlorothalonil were evaluated in the laboratory and the field against Oncomelania hupensis, the intermediate host of Schistosoma japonicum in China. The three chemicals were very effective against O. hupensis in the laboratory. The molluscicidal activities found in the field trials suggest that Tribromosalan and Cartap may be used as practic...
A protocol was created for performing geographically randomized snail surveys for schistosomiasis research using the global positioning system (GPS). This protocol differs from traditional surveys in its ability to accurately map and measure the spatial distribution of snail habitat. The protocol was used to map irrigation ditches, the primary habitat for Oncomelania hupensis, in two residence ...
The molluscicidal effects of Eomecon chionantha alkaloids (ECA) against Oncomelania hupensis snails were determined by immersion method. The molluscicidal effect was positively related to ECA concentration, immersion time and temperature of the immersion solution. The mortality of the snails reached 100% by 72 hours in ECA at a concentration of 2.5 mg/l at 25 degrees C. The alanine aminotransfe...
