Résumé : The problem posed in Brazil since 1984 by Rhammatocerus schistocercoides-an important pest locust in the Mato Grosso state - is exemplary. It shows how the occurrence of a new locust phenomenon has given rise to fruitless opposition between supporters of insecticide treatments, on one hand, and environmental conservationists on the other. Extensive control measures were implemented and large quantities of insecticides sprayed, with all of the drawbacks concerning risks to the environment and to the health of the indigenous people that eat locusts. Intensive ecological field work, carried out for 10 years, gradually has revised our understanding of the origin of this species' outbreaks and the way to control them. On the basis of solid scientific experience, solutions can now be posed that are realistic, efficient, respectful of the environment and the interests of farmers and indigenous populations.
