“…The decrease in activity of the antioxidative defense system enzymes is usually connected with damage to different cellular molecules, such as DNA, lipids and proteins [46], which leads to a lower enzyme production. The results of our experiment showed that the activity of GST in ECB larvae treated with chlorantraniliprole was significantly higher when compared to the control group, while the activity of GR was considerably higher when compared to the group treated with indoxacarb.…”

The European corn borer (Ostrinia nubilalis) is one of the most important insect pests of maize, and has a significant impact on the production of this crop. In this work, we examined the effects of different insecticides on the antioxidative defense system of O. nubilalis larvae. The experimental setup consisted of a completely randomized block design with 4 replicates. Four experimental groups were formed as follows: control (C), indoxacarb (250 mL ha-1), chlorantraniliprole (100 mL ha-1) and the chlorantraniliprole+lambda cyhalothrin (200 mL ha-1) group. Larvae from maize stems were collected 20 days after insecticide application and the whole larvae were homogenized. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione S-transferase (GST), and the total amount of free SH groups were assessed. Comparison of the experimental groups showed that indoxacarb significantly affected the activities of GST, GPx and the total amount of free SH groups, while chlorantraniliprole significantly affected the activities of SOD, CAT, GST and the total amount of free SH groups, while chlorantraniliprole+lambda cyhalothrin significantly affected the activities of CAT, GST and the total amount of free SH groups. The results show that exposure to insecticides considerably affects the antioxidative defense components of the European corn borer larvae, especially chlorantraniliprole (T2).

“…We selected tadpoles as test organisms because they are sensitive indicators of ecosystem deterioration by environmental pollutants (Waddle, 2006), given their permeable skin, unshelled (not amniotic) eggs, and a complex life cycle that exposes them to changes in both aquatic and terrestrial environments (Blaustein et al, 1994). Accordingly, some ecotoxicological studies with amphibians have suggested the measurement of certain enzymes involved in the mechanism of contaminant toxicity as important biomarkers to detect potential adverse effects of pesticides (Ossana et al, 2013;Robles-Mendoza et al, 2011;Güngördü and Uçkun, 2015;Güngördü et al, 2016). We expect that our results will provide valuable information about the impact of diet on OP toxicity, which may be of concern in regulatory toxicology (toxicity testing and ecological risk assessment framework).…”

“…Peroxidation can occur in lipids of cell membranes as result of exposure to of different classes of stressors (Oost et al, 2003). Under stress conditions, lactacte dehydrogenase (LDH) enzyme activity can be used as biomarker since anaerobic metabolism might be switched on due to increased energy demand such as detoxi cation mechanisms to cope with exposure to chemical stressors (Diamantino et al, 2001;Güngördü et al, 2016;Wen et al, 2017a).…”

Many personal care products integrate UV-filters, such as 4-methylbenzylidene camphor (4-MBC) which has been detected in aquatic habitats. Possible effects of 4-MBC to aquatic organisms have been poorly studied. Therefore, the main objective of this work is to study the effects of 4-MBC exposure to Solea senegalensis during metamorphosis, a sensitive life stage of this flatfish. To achieve this, at the beginning of metamorphosis (13 days after hatching, dah) fish were exposed to 4-MBC (0.2–2.0 mg L− 1) for 48 h. After this period, fish were transferred to clean medium and were fed and maintained until more than 80% of fish in control group completed the metamorphosis (24 dah). Mortality, malformations and metamorphosis progression were studied on a daily basis. In addition, growth, behavior and biochemical markers of neurotransmission (acetylcholinesterase, AChE), oxidative stress (catalase, CAT; glutathione S-transferase, GST, and lipid peroxidation, LPO) and anaerobic metabolism (lactate dehydrogenase, LDH) were determined at the end of the experiment. An acceleration of metamorphosis progression was observed during and 2 days after the 4-MBC exposure in all concentrations tested. In addition, decreased length, inhibition of CAT activity and induction of oxidative damage (LOEC = 0.928 mg L− 1 4-MBC for length, CAT and LPO) were observed. A short-term exposure to 4-MBC at the onset of metamorphosis, a critical period of development, affected S. senegalensis at several levels of organization, even after nine days in clean medium, including growth and metamorphosis progression, suggesting possible long-term adverse effects to this species.
