Bien que consid r e comme culture mineure ou culture << orpheline >> le voandzou peut contribuer efficacement r soudre d'importantes probl matiques mondiales telles que la faim, la pauvret et l'adaptation aux changements climatiques. Il est une source prometteuse de prot ines v g tales et a l'avantage d'avoir de nombreux morphotypes largement cultiv s par les populations rurales. Malheureusement pendant le stockage cette ressource est en proie une pression des ravageurs qui engendrent des pertes quantitatives et qualitatives. L'objectif de cette tude, est de d terminer en condition contr l e, le degr de vuln rabilit de 40 morphotypes cod CM/R gion/Collection/no(01 40) vis- -vis de Callosobruchus maculatus. Au cours de trois campagnes de collecte des donn es et interviews men es dans le Cameroun septentrional, des informations sur la diversit de graines de voandzou ont t collect es, puis ramen es en laboratoire. L' valuation de la sensibilit vari tale de cette collection, a repos sur l'analyse des param tres qui d finissent l' chelle de sensibilit savoir: le nombre d'oeufs pondus, le nombre d'oeuf et de larves morts, le nombre d'individus merg s et l'indice de susceptibilit . Il ressort que le nombre d'oeufs pondus par C. maculatus est compris entre 56,5[+ or -]19,65 (CM/EN/DW/01) et 111,5[+ or -]58,69 CM/EN/MC/34. Le taux d' mergence varie entre 58,23% (CM/EN/EA/02) et 96, 70% (CM/EN/DW/24). L'analyse statistique des valeurs li es l'indice de susceptibilit montre une diff rence tr s hautement significative (p < 0,0001). Il existe une forte corr lation n gative entre l' mergence et la mortalit larvaire (r = -0,97). La classification ascendante hi rarchis e a permis de r aliser un dendrogramme regroupant les morphotypes en 7 classes distinctes en fonction du degr de susceptibilit . La classe I montre de fa on sp cifique trois morphotypes les plus r sistants aux attaques de la bruche (CM/EN/DW/09, CM/EN/AE/02 et CM/EN/MC/49) dans cette exp rimentation. Les vari t s qui ont pr sent une r sistance la bruche peuvent tre adopt es ou exploit es pour le d veloppement des vari t s plus int ressantes pour les producteurs, les consommateurs et les transformateurs. D'autre part, compte tenu des changements globaux qui affectent l'agriculture en g n rale et certaines esp ces mineures dites n glig es et sous-utilis es en particulier, il serait imp ratif de trouver des strat gies de conservation efficaces court, moyen et long terme pour r pondre la demande alimentaire de plus en plus importante au Cameroun.

It is a promising source of plant protein and has the advantage and has the advantage of having numerous morphotypes to be widely cultived by rural populations. Unfortunately during storage this resource is subject to pest pressure which leads to quantitative and qualitative losses. The objective of this study is to determine, under controlled conditions, the degree of vulnerability of 40 morphotypes code CM/Region Collection/ no(01 to 40) collected with regard to C. maculatus. During three campaigns of data collection and interviews conducted in northern Cameroon, information on the diversity of voandzou seeds was collected, seeds were collected in the field during three campaigns in the three northern regions of Cameroon, then brought back to the laboratory. The assessment of varietal sensitivity for this collection, is based on an analysis of the parameters that define the sensitivity scale, namely: the number of eggs laid, the number of dead eggs and larvas, the number of emerged individuals and the susceptibility index.The number of eggs laid by C. maculatus ranged from 56.5[+ or -]19.65 (CM/EN/DW/01) to 111.5[+ or -]58.69 CM/EN/MC/34. Emergence rates ranged from 58.23% (CM/EN/EA/02) to 96.70% (CM/EN/DW/24). Analysis of susceptibility index values shows a highly significant difference (p < 0.0001). There is a strong negative correlation between emergence and larval mortality (r = -0.97). Cluster analysis was used to produce a dendrogram grouping morphotypes into 7 distinct classes according to degree of susceptibility. Class I specifically shows three of the most resistant morphotypes to bruchid attacks (CM/EN/DW/09, CM/EN/AE/02 and CM/EN/MC/49) in this experiment. Varieties that have shown a resistance to bruchid beetle may be adopted or exploited for the development of more interesting varieties for growers, consumers and processors. On the other hand, given the global changes affecting agriculture in general and certain neglected and under-utilised minor species in particular, it would be imperative to find effective short-, medium- and long-term conservation strategies to meet the growing demand for food in Cameroon Key words: Bambara groundnut, susceptibility index, resistance, evaluation, weevil, attack larval emergence, Cameroun, INTRODUCTION Les estimations r centes de l' tat de la s curit alimentaire et de la nutrition dans le monde, parues en juillet 2022, font tat de ce que le [...]
