Background: Populations of herbivorous insects may become genetically
differentiated because of local adaptation to different hosts and climates
as well as historical processes, and further genetic divergence may occur
following the development of reproductive isolation among populations.
Here we investigate the population genetic structure of the orchard pest
peach fruit moth (PFM) Carposina sasakii (Lepidoptera: Carposinidae) in
China, which shows distinct biological differences when characterized from
different host plants. Genetic diversity and genetic structure were
assessed among populations from seven plant hosts and nine regions using
19 microsatellite loci and a mitochondrial sequence. Results: Strong
genetic differentiation was found among geographical populations
representing distinct geographical regions, but not in host-associated
populations collected from the same area. Mantel tests based on
microsatellite loci indicated an association between genetic
differentiation and geographical distance, and to a lesser extent
environmental differentiation. Approximate Bayesian Computation analyses
supported the scenario that PFM likely originated from a southern area and
dispersed northwards before the last glacial maximum during the
Quaternary. Conclusions: Our analyses suggested a strong impact of
geographical barriers and historical events rather than host plants on the
genetic structure of the PFM; however, uncharacterized environmental
factors and host plants may also play a role. Studies on adaptive shifts
in this moth should take into account geographical and historical factors.
