Sampling sites and composition of B. tabaci genotypes collected from agroecological zones along an elevation gradient in (A) Uganda and (B) Tanzania. The map was generated by QGIS v.2.18.

Composition of B. tabaci species per field in Tanzania (n = 1983) (A) and Uganda (n = 661) (B).
Fig 3.
Phylogenetic tree generated using 102 mtCOI sequences selected from a total 1071 long sequences, with 595 base pair (bp) obtained from adult B. tabaci (cassava and non-cassava) and 14 reference sequences from GenBank.
Sequences in bold represent references from GenBank and the four new identified groups (>4% of nucleotide identity from the closest B. tabaci sequence).

Fig 4.
Different K populations of B. tabaci (A) SSA1 from Tanzania (TZ) and Uganda (UG), (B) SSA1 from Tanzania, (C) SSA1–SG3 from Tanzania and (D) non–cassava species. Structure bar plots are based on 12 microsatellite loci. Individuals were arranged according to mtCOI species assignment and field number separated by the black line. For each dataset, the optimal K selected by STRUCTURE HARVESTER is presented in black. DSM is Dar es Salaam.
