A simple trap for schistosome cercariae has been developed using clear nail varnish as a matrix and linoleic acid as stimulant affixed to a 75 x 25-mm glass slide. Schistosoma mansoni cercariae will attach to the surface and easily can be visualized either stained or unstained. The trap works well under laboratory and field conditions where the retrieval rate varies from 30% to 100%. Under laboratory conditions there appears to be some form of affinity for cercariae to the surface.
