Abstract. Invasive species can have an enormous effect on their surroundings in various ways. They have effects on human health and other species. Local adaptation by native species can occur, Rhagoletis pomonella and Jadera haematoloma. Recent studies show this can be achieved by other pathways than only DNA variation. Epigenetics, heritable changes in gene expression not explained by the DNA, plays a part to. DNA Methylation, probably the best studied epigenetic mechanism, causes gene silencing. Chromatin remodeling is proposed as a form of epigenetics. Histone acetylation is a more recent studied system and the final pathway is RNA mediated gene silencing. Most of the before mentioned pathways are poorly studied in relatedness to insect and host adaptation. Studies show that the effects of methylation in insects have different outcome. Computer models on the effect of plastic response and adaption show different effects with different circumstances. However when relating the above with adaptation to invasive species, it appears that epigenetics can play a positive role.
