Oedaleus senegalensis is a mainly sahelian non gregarious grasshopper which is today considered as the most important crop pest acridid, especially on millet. The species has three generations per year (rarely four) and spends the dry season as diapausing/quiescent eggs. Both photoperiod and temperature influence the induction of diapause in which O. senegalensis eggs can survive several years. Migratory movements have been reported by many authors; adults may migrate up to 350 km per night. These factors enable the species’ adaptation to its natural hostile environment. The current control strategies are based on monitoring of the oviposition sites of the dry season to predict the subsequent outbreaks in order to control early hatchlings during the following rainy season. The present work gives an overview of the current knowledge on the morphology, biology, ecology and control methods of the grasshopper.
