Tuta absoluta's population genetic structure across Africa: Two well‐delineated but weakly differentiated groups suggesting few introductions and significant gene flow Structure génétique des populations de Tuta absoluta à travers l'Afrique: deux groupes bien délimités mais faiblement différenciés suggérent peu d'introductions et un flux génétique important

Agricultural and Forest Entomology, Volume 27, Issue 2, Page 223-240, May 2025.
Abstract Describing the genetic structure and diversity of invasive insect pest populations is essential to better understand a species' invasion history and success throughout its distribution range. Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) is a destructive pest of tomato and many other solanaceous crops, with very high economic impacts. Its

Conservation genetics of the white‐bellied pangolin in West Africa: A story of lineage admixture, declining demography, and wide sourcing by urban bushmeat markets

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Our work derives from an unprecedented, exhaustive genetic survey of the pangolin trade in three countries from West Africa (Guinea, Cote d'Ivoire, and Ghana). Our study combining mitochondrial DNA sequencing and microsatellite genotyping is the first to reveal a global pattern of admixture between two of the six mitochondrial lineages previously ...
