MATERIALS AND METHODSBoth C. dubia and P. promelas were taken from cultures maintained at the Ohio Environmental Protection Agency (EPA) bioassay laboratory. Less than 24H old P. promelas and C. dubia neonates were used in both acute and sub-chronic tests. Reproductive performance of the C. dubia population was assessed by subjecting them to quality assurance tests (Horning and Weber 1985) prior to use of neonates in the toxicity tests. H. limbata nymphs were collected from wild populations. The length of the nymphs used in the acute tests was between 12 and 33 mm.The components used in these tests were the molluscicide H-130 and bentonite clay. The quaternary ammonium compound H-130 is positively charged. When in the presence of bentonite clay, the cationic molluscicide is attracted to the anionic charge on the surface of the clay which is the basis for use of the clay as a sorbent medium. Most
