Results of Laboratory Screening Tests of Chemical Compounds for Molluscicidal Activity

Abstract

Summary Seven hundred and one phenolic type compounds were tested for their activity against Australorbis glabratus, the snail vector of Schistosoma mansoni in the Western Hemisphere. Correlations have been drawn between structure of the chemical compounds and molluscicidal activity. The most active compounds were fund among the highly halogenated phenols, the dinitroalkyl- and arylphenols, the “bisphenol” type of compound and the mercurated phenols. On the basis of availability and cost, pentachlorophenol or its salts would appear to be the molluscicide of choice at this time.
