Macroinvertebrate communities were observed in the rivers of Nuku-Hiva (Marquesas Islands, French Polynesia). Two sampling excursions were undertaken during hydrologically stable periods: April-May 1991 (before treatments) and March 1994 (one year after antisimuliid applications using Abate® to all the running waters on the island). Results from 55 hand-net samples (10 min each) revealed an altitudinal continuum and the effects of eutrophication. Effects of antisimuliid treatments were not perceptible at this scale of observation.
