Abstract
Adult Urosalpinx were exposed to various combinations of two pesticides ("Sevin", a methyl carbamate, and "Polystream", a mixture of chlorinated benzenes) recommended for oyster predator control by the Milford Biological Laboratory of the U. S. Fish and Wildlife Service. Concentrations used were within the recommended range, and the field procedure suggested was modified by us for application in laboratory trays. Under controlled laboratory conditions, Polystream used alone killed half the animals within a period of 5. 5 to 6.8 days. The use of Sevin, which is highly toxic in crustaceans, is therefore questionable.
