Demographic history and population structure of Phlebotomus argentipes (Diptera: Psychodidae) complex, the leishmaniasis vector in Sri Lanka
Fig 5
Demographic expansion model comparisons based on concatenated sequence alignments of five Phlebotomus argentipes s.l. populations in Sri Lanka.
Observed mismatch distributions are shown in red, and expected distributions under the sudden expansion model are shown in blue. These curves illustrate historical population dynamics, providing insights into past expansions or bottlenecks within each population. Panels: (A) Anuradhapura; (B) Balangoda; (C) Mirigama; (D) Medirigiriya; and (E) Hambantota.
