a Sample projection of the four populations of An. coluzzii females onto the first discriminant plane of the LDA. Blue and red samples represent specimens reared under RS and ODS conditions, respectively. The singular values correspond to the ratio of between-class/within-class inertias. b The correlations circle depicts the normed relation between each metabolite and first discriminant plane. Amino acids are identified using the European abbreviation index. c-d The relative contributions of the 29 retained metabolites to LD1 and LD2
