Anthropogenic activity in industrial development has imposed great threats to the environment and wildlife in the form of persistent organic pollutants. Polycyclic aromatic hydrocarbons (PAH) tend to accumulate in vegetation foliage which is the main food source of polyphagous insect species Lymantria dispar L. Origin and multigenerational adaptation of L. dispar population to environmental challenges strongly condition the enzymes’ sensitivity to pollutants. In this study, our aim was to investigate response of the superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) to the chronic dietary exposure of benzo[a]pyrene in the midgut tissues and hemolymph of two L. dispar populations originating from unpolluted and polluted forest habitat. Midgut tissue of the larvae from the polluted forest showed significant increase in SOD, CAT and GST activity, while in unpolluted forest's larvae SOD and CAT showed elevated activities in hemolymph. L. dispar populations adapted to different level of pollution in their environment and expressed distinct tissue-dependent antioxidative enzyme sensitivity to benzo[a]pyrene diet, implying high potential for further elucidation of these enzymes as molecular biomarkers.
