The molluscicidal properties of Apodytes dimidiata subsp. dimidiata (Icacinaceae).

The molluscicidal and piscicidal activity of extracts from the leaves, berries and bark of the tree Apodytes dimidiata were evaluated experimentally. The leaves were highly toxic to both Bulinus africanus and Biomphalaria pfeifferi, the intermediate host snails of Schistosoma spp. B. pfeifferi profusely exuded mucus which appeared to render some protection against the toxic substance(s) of the plant but did not prevent their eventual demise. The LC10 after one-hour exposures of fish (Oreochromis mossambicus) was within molluscicidal levels.
