In a single Portuguese population tested, the number of alleles per locus ranged from 2 to 12, and observed heterozygosity from 0.07 to 0.83. Cross amplifications gave satisfactory results for most loci in the T. pityocampa/T. wilkinsoni complex but proved to be of low interest for other species. These markers will be valuable to investigate the population genetic structure of this forest pest, particularly for the expanding populations at the northern limits of its range, and for a new phenological race discovered in Portugal

For this purpose, a total of 6 highly-variable nuclear markers, microsatellites, were developed of which five were largely used for genotyping. Allelic diversity ranges from 8 to 21 according to locus). Larvae were sampled in more than 50 sites throughout the historical and expanding areas in France, 30 nests having been collected on different trees at each site to minimize consanguinity. Microsatellite analysis did not show any isolation by distance in the historical area when the flight-of-bird distances are considered. However, when the values of Fixation index (Fst) were plotted against distances circumventing Massif Central, isolation by distance was verified (Mantel test). We therefore considered the existence of two expanding historical corridors, northwestern and northeastern respectively, from the Mediterranean native area. The Massif Central thus acted as a strong barrier even if its relief is moderate. However, this barrier seems no more tight, probably in direct relation with global warming. Genetic studies proved that the welldifferentiated populations from East and West nowadays communicate through the Allier valley at least, the apparently western populations from Allier belonging to the eastern system. Studies at a larger scale using a mitochondrial marker (COI, maternally-inherited and more conserved) proved that the Pyrénées chain also constituted a key barrier for PPM expansion, clearly separating the Iberian and French populations. By contrast, the western Alps did not constitute a similar barrier. Expanding populations from Italian Piémont and French Briançonnais showed only a very weak genetic differentiation although there are high mountains separating them. Recent trappings of males during 2004 and 2005 at the Col of Montgenèvre (1850m altitude), which separates the two areas, confirmed that gene flow actually exists between these alpine valleys. However, the situation may be different in other valleys of Northern French Alps (Tarentaise) due to higher relief. In the expansion area of Paris Basin, the populations of the northern front appeared slightly but significantly divergent from these of the core area and from these of the Eastern Front, suggesting two routes for PPM expansion in that area. In the near future, genotyping of males trapped beyond the front as well as of isolated colonies far beyond may allow to precise the origin of the funders and the preferred routes of expansion. An important challenge remains to integrate these genetic data into models in order to improve the forecast of PPM expansion.
