The Mediterranean fruit fly (medfly) Ceratitis capitata (Diptera: Tephritidae) is known to be one of the most destructive and economically important agricultural pests worldwide. Several previous research projects have investigated the genetic makeup of regional populations of this pest and the relationships of populations from different areas of the world, including countries from the Mediterranean region. However, previously, little information has been reported on populations from Tunisia, despite the fact that this pest occurs in several agriculturally sensitive areas of this country. In order to study the genetic diversity of medfly populations within Tunisia, specimens were collected from the Coastal, Northern, Central and Southern regions of the country. Results using mitochondrial ND5 sequences show the presence of distinct haplotypes. This data used to analyze the levels of genetic variability within and between populations from Tunisia as well as from other countries in the Mediterranean region (Morocco and Israel) and in the world (Seychelles and Hawaii). This study also leads to a better understanding of the origin of new infestations and the colonization processes involving this pest.
