Cross-amplification of microsatellites from the codling moth Cydia pomonella to three other species of the tribe Grapholitini (Lepidoptera: Tortricidae).

This study examined cross-species amplification of 33 microsatellite markers, previously developed for Cydia pomonella, in three related fruit moth species of the same tribe (Grapholitini), namely Grapholita molesta, Grapholita funebrana and Grapholita lobarzewskii. Eight microsatellite loci yielded polymorphic products for G. molesta, nine for G. funebrana and 11 for G. lobarzewskii. At all these loci, the number of alleles ranged between four and 11 in G. molesta, and between four and nine in G. funebrana and G. lobarzewskii each. The successful cross-amplified loci can be used for research on population genetics and gene flow of the three target species.
