Le Bombyx disparate, ravageur des forêts de feuillus est désormais présent partout dans l'Hémisphère nord. Il est parmi les plus étudiés pour la science fondamentale et appliquée. Depuis un siècle, Lymantria dispar se manifeste de façon périodique par des défoliations spectaculaires des fagacées dans beaucoup de pays de son aire de distribution et a fait l'objet de recherches notamment au Maroc et en Italie. En Algérie, les pullulations de ce ravageur ont été signalées depuis 1925, puis d'une manière discontinue dans les diverses forêts de chêne du Nord du pays. L'importance économique considérable des défoliations périodiques particulièrement en chênaies et le manque de données nous ont incités dans le choix du sujet. Cette recherche fournira une base scientifique fondamentale utile pour des traitements futurs des peuplements menacés par les pullulations de ce défoliateur.
