英文摘要	The desert locust,Schistocerca gregariaForskal, 1775, is a major threat to agriculture. Refining our knowledge on its spatial distribution is a key point for its preventive management. To do so, we used in Chad a method of spatial smoothing of densities upon 7014 survey points (1965-1971 and 1986-2017) of the desert locust to develop seasonal distribution maps for invasion and remission periods. Three zones corresponding to breeding and gregarization areas have been identified: (1) Kanem/lake Chad, (2) Batha, (3) Ennedi. The first one may be a new gregarization area. These zones add to the Tibesti mountains where locust reports are less frequent than in the past, due to insecurity. More regular surveys should confirm that the distribution of the desert locust has recently changed.
