Investigating global invasion routes of the harlequin ladybird (Harmonia axyridis) using mtDNA


Abstract: Although species invasions have important ecological and economical consequences,there is still much we do not understand about why only certain species become successfulinvaders, and what impacts they have on other species. Molecular techniques can be used to gainvital information on invasion dynamics, so as part of an ongoing study, we have usedmitochondrial DNA sequence data to investigate the global invasion of Harmonia axyridis, andparticularly the characteristics of the founding population(s). This will also complement datacurrently being gathered on microsatellite genotype and endosymbiont presence to provide apowerful dataset for understanding the invasion history of this species, and, more broadly, toattempt to determine what factors might make an invasive species successful.
