Abstract

Mortality and infectivity or Schistosoma mansoni cercariae were tested against various concentrations of controlled release copper sulphate (EC-8) and tributyltin fluoride (CBL-9B). The results indicate that survival of cercariae varied with concentrations of molluscicide and times of exposures. Statistical analysis reveals that LC50and LC90for EC-8 were 1.18 mg/l/hour and 1.82 mg/l/hour while LC50and LC90forCBL-9B were 16.8/ug/l/hour and 21.7/ug/l/hour respectively. Sublethal concentration of both molluscicides reduced cercarial infectivity considerably. The doses of 0.25 to 0.5mg/l/hour for EC-8 and 2.0 to 6.0/ug/l/hour for CBL-9B were found to be sufficient to inhabit cercarial penetration of the host skin. © 1982, Cambridge University Press.
