Résumé : Brazil, Colombia and Venezuela have, for several years, been facing severe outbreaks in species belonging to the genus #Rhammatocerus#. This genus is in need of revision and until now it was not certain that the populations involved North and South of the amazonian rain forest belonged to the same species or not. Our studies show that, in fact, a single species with a large distribution area is involved : #R. schistocercoides# (Rehn, 1906). Biological data, the dynamic of the invasions and hypotheses on the outbreak determinism in the Northern and Southern parts of the distribution area are synthesized and discussed.
