Résumé : Nine microsatellite markers were isolated from the entomopathogenic haploid fungus Paecilomyces fumosoroseus. Genetic diversity was assessed in 26 P. fumosoroseus isolates originated from the whitefly Bemisia tabaci collected in various geoclimatic areas. Eight loci were polymorphic with an observed number of alleles ranging from two to six. The loci differentiated some isolates and group of isolates according to their geographical location, showing promise for the study of gene flow. All loci failed to give clear amplifications in P. fumosoroseus isolates from hosts other than B. tabaci. These microsatellite markers provide powerful tools for ecological, epidemiological, and population genetic studies.
