The Indian leaf-mining fly Hydrellia pakistanae Deonier was released i
n the United States during October 1987 as a potential agent for the b
iological control of the submersed aquatic plant, Hydrilla uerticillat
a (L.f.) Royle. Since then, nearly 3 million individuals have been rel
eased in four states at over 25 separate locations. Hydrellia pakistan
ae is now permanently established at many locations in Florida as well
as other portions of the southeastern United States. Despite early fa
ilures, populations established from at least 70% of the release attem
pts. Modifications of rearing and release procedures that considered t
he biology of the agent in relation to various habitat characteristics
facilitated successful establishment. (C) 1997 Academic Press
