ABSTRACTThe present study analyzes and compares a battery of biomarkers in females and males of water bug Belostoma elegans from two streams: one polluted with organic matter (OMS) and the other considered as reference site (RS). Insect collection was carried out during spring-summer season. Glycogen and lactate content were analyzed in insects as well also activities of the enzymes pyruvate-kinase and lactate dehydrogenase. Lipid and fatty acid (FA) composition analysis was performed. The activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) were assayed. Finally lipoperoxidation (LPO), protein oxidation (OP) and the content of reduced glutathione (GSH) were measured. In general no significant differences were observed in all biomarkers analyzed between both sexes of water bug except lactate concentration which was higher in males than in females (p
