Resume-Callosobruchus maculatus (Coleoptera: Bruchidae) ou bruche du niebe est un des ravageurs les plus redoutabies des gralnes de niebe en Afrique tropicale. En zone rurale oil les techniques de conservation des denrees sont rudimentaires, ce ravageur entraine des pertes postrecolte pouvant atteindre 100 % en quelques mois. L'importance des dlgats occasionnes a Justine 1 le dlveloppement de methodes de contr61e efflcaces et applkables en milieu villageois. L'ensemble de ces methodes sont passees en revue et l'applicabilite de chacune d'entre elles est dlscutie. II s'avere que la lutte chimique est inadaptee au monde rural compte tenu de son cout et des dangers lies a son utilisation. Les nombreux travaux effectues sur la resistance varietale ont permis d'identifier des varietes plus ou moins resistantes a ce ravageur; toutefois, ces varietes sont souvent peu inteYessantes du point de vue agronomiques. L'incorporation de cette resistance dans des varietes acceptables n'a pas encore donnl satisfaction. Les methodes physiques de lutte sont souvent insutfisantes pour assurer une protection efficace des stocks et de plus, demandent un £quipement et des connaissances techniques approfondles. Quant a la lutte biologique, bien que prometteuse, elle n'en est encore qu'au stade de recherche. Toutes ces restrictions placent les methodes traditionnelles de lutte parmi les plus efficaces et les plus usitees. Ainsi, l'utilisation de la flore indigene et de ses derives, de substances inertes, le controle de l'humidite et de la temperature, ainsi que 1'application des methodes preventives entrafnent une reduction significative des populations de C. maculatus et done, diminuent les pertes post-recolte.Abstract-Callosobruchus maculatus (Coleoptera: Bruchidae), commonly known as the cowpea seed beetle, is the most important pest of stored cowpea in tropical Africa. In rural area where preservation techniques and facilities are limited, it causes post-harvest weight and quality losses. The importance of damages which can reach 100% in a few months justifies the development of effective and appropriate control methods in the villages. All these control methods and their applications are discussed in this paper. Chemical control is inappropriate at farm level, because of its cost and hazards. The many studiesconducted on varietal resistance have enabled identification of varieties that are more or less resistant to this pest; however, the varieties are often of little Interest from the agronomic point of view. The incorporation of that resistance in cultivated varieties Is hi progress. The physical control methods are inadequate because their application requires equipment and technical knowledge which are not found in rural areas. Biological control is an attractive alternative but is still at an experimental stage. AU these limitations support promotion of traditional control methods. Among them, the use of inert substances as well as indigenous plants or their by-products have given, in many cases, a satisfactory control of C. ma...
