Understanding the cellular stress response in honey bees will
significantly contribute to their conservation. The aim of this study
was to analyze the response of the antioxidative enzymes superoxide
dismutase and catalase in honey bees related to the presence of toxic
metals in different habitats. Three locations were selected: (i) Tunovo
on the mountain Golija, as control area, without industry and large
human impact, (ii) Belgrade as urban area, and (iii) Zajaca, as mining
and industrial zone. Our results showed that the concentrations of lead
(Pb) in whole body of bees vary according to habitat, but there was very
significant increase of Pb in bees from investigated industrial area.
Bees from urban and industrial area had increased expression of both
Sod1 and Cat genes, suggesting adaptation to increased oxidative stress.
However, in spite increased gene expression, the enzyme activity of
catalase was lower in bees from industrial area suggesting inhibitory
effect of Pb on catalase. (C) 2015 Wiley Periodicals, Inc.
