Abstract
In order to assess the genetic differentiation among Tunisian clones belonging to the Myzus persicae complex (M. persicae (Sulzer), M. antirrhinii (Macchiati) and M. nicotianea Blackman), the molecular technique of microsatellites was used in this study. These markers offer sensitivity and are useful in population genetic studies of parthenogenetic organisms. Here, nine polymorphic microsatellite loci were amplified to distinguish between six parthenogenetic clones belonging to M. persicae complex collected from two different Tunisian areas. Interestingly, this technique allowed discrimination between five different genotypic classes among the six clones. Furthermore, analysis of genetic relatedness between the genotypic classes revealed that two Tunisian clones did not cluster either in M. persicae or in M. antirrhinii taxa, whereas, the four other Tunisian clones clustered into the M. persicae Sulzer taxa.
