Summary. -Prionyx thomae (Fabricius) (Hym., Sphecidae) attacks on Rhammatocerus schistocercoides (Rehn) (Orth., Acrididae) were observed in savanna areas in the State of Mato Grosso, Brazil. These regions are traditional zones where grasshoppers pullulate ; but since 1984, after recent agricultural colonization, the insect has become a serious worry for farmers and entomologists. Wasp attack behaviour, observed in the field, is described and compared with records in the literature. The role of wasps as natural control agent for grasshopper populations is discussed.Résumé. -Des attaques dePrionyx thomae (Fabricius) (Hym., Sphecidae) sur Rhammatocerus schistocercoides (Rehn) (Orth., Acrididae) ont été observées dans des zones de savanes de l'...
