Résumé
Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) is a destructive pest of tomato and many other solanaceous crops, with very high economic impacts. Its invasion threatens food security in a large part of the globe, in areas such as sub-Saharan Africa where the agricultural resilience has already been weakened by rapid human-induced changes due in particular to population growth, increased trade and global change. This work aimed to investigate the diversity and genetic structure of 60 populations of T. absoluta using microsatellite markers, with a particular focus on sub-Saharan Africa. NB: Loci with a mean estimate of null-allele frequency greater than 0.15, significant heterozygote deficiencies after Bonferroni correction and a highly substantial inbreeding coefficient were not used in the analyses in the associated paper. They are shown in grey in the dataset (Ta222 and Ta252).
