Fig. 4

a Dendrogram based on a composite correlation index (CCI) matrix of spectra obtained from specimens of Bi. pfeifferi and Bu. forskalii selected at random from the four populations: ten spectra for Bi. pfeifferi and Bu. forskalii from the NW (SRD), ten for the laboratory strain Bi. pfeifferi from the SE (Kedougou), four for the wild strain and three spectra for Bu. forskalii from Central Senegal (Diourbel). b–g Characteristic peaks in the individual clean spectra of specimens from the north-west Bu. forskalii (red curves) and the north-west Bi. pfeifferi (blue curves) populations relative to specimens from central and South-Eastern Senegal, respectively, obtained by manual analysis in FlexAnalysis software: NW Bu. forskalii (b: 5161 Da, c: 5531 Da and d: 10,086 Da) and NW Bi. pfeifferi (e: 5442 Da, f: 5763 Da and g: 5501 Da). The x-axis indicates ionic mass values in Dalton (Da) and the y-axis indicates peak intensities expressed in arbitrary intensity units (a.u)
