Objectif : contribuer a mettre en place une lutte integree contre la proliferation de Cissus quadrangularis L. dans le Parc National des Iles de la Madeleine (PNIM) au Senegal. Methodologie et resultats : Des essais de controle biologique et physique ont ete testes. La lutte biologique a ete basee sur la collecte et l’elevage en laboratoire de chenilles capables de degrader les tiges et les feuilles de C. quadrangularis . Quant a la lutte physique, elle a consiste a arracher les individus de l’espece et a suivre la capacite de regeneration des residus de la plante apres differents traitements. Les resultats obtenus ont montre qu’une lutte biologique est envisageable a travers la chenille de   Hippotion celerio, phytophage de C. quadrangularis . Aussi, les tests de controle physique ont montre que l’arrachage manue  semblerait etre efficace quand les fragments de la plante sont elimines par  incineration hors du parc. Conclusion et application : La combinaison de ces deux methodes pourrait permettre de reduire et de limiter la superficie d’occupation de C. quadrangulari s dans le PNIM. Mots cles : Cissus quadrangularis , plante proliferante, Parc National des Iles de la Madeleine, lutte physique, lutte biologique, Hippotion celerio. Introduction : Help put up a integrated fight against the proliferation of Cissus quadrangularis L . in the National Park des Iles de la Madeleine (NPIM) in Senegal. Methodology and results : of trying to biological and physical control. Biological control has been based on collecting and raising caterpillars capable of degrading the stems and leaves of the concern species. As for the physical struggle, it was to snatch individuals of C. quadrangularis and follow the regenerative capacity of the plant residues after different treatments. The results have shown that biological control is possible through the caterpillar of Hippotion celerio, phytophage of C. quadrangularis . Also, physical control tests have shown that manual eradication would seem to be effective when the fragments of the plant are disposed of by incineration out of the park. Conclusion and application : The combination of these two methods could reduce and limit the occupancy area and possible spread of C. quadrangularis in NPIM. Keywords : Cissus quadrangularis , Alien plants, National Park des Iles de la Madeleine, physical control, biological control, Hippotion celerio.
