Plant vegetation accumulates polycyclic aromatic hydrocarbons (PAHs) among which benzo[a]pyrene (B[a]P) is recognized as being very toxic, including cancerogenic. Lymantria dispar L. larvae are sensitive to changes in the environment, providing potential signs of pollutant presence. We examined the chronic effects of two concentrations of B[a] P on the activity of carboxylesterase (CaE), acetylcholinesterase (AChE) and heat shock protein 70 (Hsp70) levels in the brain tissue of two populations of L. dispar larvae, originating from unpolluted and polluted habitats. We found that the relative growth rate was significantly lower in both populations and that only larvae from polluted forests were sensitive to low B[a]P concentrations, exhibiting a significant increase in brain tissue CaE activity and Hsp70 concentration. AChE activity showed no changes in response to B[a]P exposure in either population. Examined biochemical parameters indicate that their sensitivity to chronic treatment with B[a]P was highly dependent on the pre-exposure history of L. dispar larvae, suggesting that they could be promising biomarkers of B[a]P and PAH pollution in forest ecosystems
