Quelques aspects ecologiques de la dynamique spatio-temporelle des populations d\'Altises Podagrica spp. ont ete etudies dans les zones cotonnieres de la Cote d\'Ivoire, en suivant l\'evolution des effectifs et des degâts sur deux types de varietes de cotonniers (cotonnier glandless et cotonnier classique) et sur deux plantes hotes (le gombo et le jute). Il ressort de ce travail que selon les localites, 3 a 6 generations se chevauchent durant la campagne agricole. Les fluctuations et les niveaux des infestations dependent desfacteurs climatologiques (pluviometrie, humidite relative, ETP, temperature), de la date de semis, de la taille et la localisation de la parcelle ainsi que de la disponibilite des plantes-hotes. Sur la base de ces resultats, des methodes culturales de lutte appropriees contre les Altises ont ete recommandees : culture des varietes glandless sur de grandes superficies, exclusivement au nord du 9e parallele et destruction des cotonniers apres la recolte ainsi que les plantes-hotes Some ecological parameters of the population dynamics of the flea beetles Podagrica spp. were studied in the cotton growing area of Cote d\'Ivoire. Population densities and damaged plants were scouted on two cotton varieties (glanded and glandless cotton) and two host plants (okra and jute). Data revealed, according tolocalities, that 3-6 overlapping generations of flea beetles occurred during the cotton growing season. Fluctuations and infestation levels depended on climatic factors (rainfall, relative humidity, ETP, temperature), cotton sowing dates, size and location of cotton fields, as well as on the presence of host plants. Based on these results, appropriate cultural methods to control flea beetles are recommended : cultivation of glandless cotton on large plots exclusively in the northern region above the 9th parallel, destruction of cotton plants after harvest and the host plants.
