This study aimed to examine the effects of ubiquitous polycyclic
aromatic hydrocarbon fluoranthene, supplemented to an artificial diet,
on the fitness-related traits and activity of midgut antioxidative
enzymes-superoxide dismutase (SOD) and catalase (CAT), and expression of
their isoforms in the fifth-instar gypsy moth Lymantria dispar L.
Prolonged duration of development and reduced weight and relative growth
rate were recorded in larvae reared on the diets supplemented with
different concentrations of fluoranthene. SOD and CAT activities were
significantly higher in the midguts of fluoranthene-treated larvae,
compared to that of the control group. Different expression patterns
were detected for SOD as well as for CAT isoforms, depending on the
supplemented concentration of fluoranthene. Obtained results suggest
that the activity of these enzymes in gypsy moth larvae may be used as
biomarkers for assessing pollution, even at low concentrations of the
pollutant.
