Polycyclic aromatic hydrocarbons (PAHs) may affect biochemical and physiological processes in living
organisms, thus impairing fitness related traits and influencing their populations. This imposes the need
for providing early-warning signals of pollution. Our study aimed to examine changes in the activity of
acetylcholinesterase (AChE) and the concentration of heat shock proteins (Hsp70) in homogenates of
brain tissues of fifth instar gypsy moth (Lymantria dispar L.) larvae, exposed to the ubiquitous PAH,
fluoranthene, supplemented to the rearing diet. Significantly increased activity of AChE in larvae fed on
the diets with high fluoranthene concentrations suggests the necessity for elucidation of the role of AChE in these insects when exposed to PAH pollution. Significant induction of Hsp70 in gypsy moth larvae reared on the diets containing low fluoranthene concentrations, indicate that changes in the level of Hsp70 might be useful as an indicator of pollution in this widespread forest species.
