Dimilin (diflubenzuron), a new insecticide that inhibits chitin synthesis in insects, was found to be acutely and chronically toxic to an estuarine mysid shrimp, Mysidopsis bahia. The 96-h LC50 was 2.06 µg/litre, the 21-day LC50 1.24 µg/litre. Significantly, a 28-day exposure to an estimated concentration of 0.075 µg/litre decreased the production of offspring per female mysid. Data from the chronic tests suggest that the test concentrations not only decreased reproduction in the parents but also affected the reproduction of the progeny. The loss in reproductive success occurred even when the exposed parents or progeny had been moved to water that contained no Dimilin. Should Dimilin reach estuarine waters, the larval or the juvenile stages of other nontarget estuarine crustaceans may be threatened in a manner similar to that observed with M. bahia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
