dc.description.abstract | Organisms live in complex multivariate environments. In agroecosystems, this complexity is often human-induced as pest individuals can be exposed to many xenobiotics simultaneously. Predicting the effects of
multiple stressors can be problematic, as two or more stressors can have interactive effects. Our objective
was to investigate whether indirect glyphosate-based herbicide (GBH) exposure of the host plant has
interactive effects in combination with an insecticide (azinphos-methyl) on an invasive pest Colorado
potato beetle (Leptinotarsa decemlineata Say). We tested the effects of GBH and insecticide on the
survival, insecticide target genes expression (acetylcholinesterase genes) and oxidative status biomarkers
[glutathione S-transferase (GST), glucose-6-phosphate dehydrogenase (G6PDH), glutathione reductase
homolog (GR), glutathione peroxidase homolog (GPx), total glutathione (totGSH), glutathione reducedoxidized (GSH: GSSG), catalase (CAT), superoxide dismutase (SOD), lipid hydroperoxides]. We found that
exposure to indirect GBH has no single or interactive effects in combination with the insecticide on larval
survival. However, prior exposure to GBH inhibits Ldace1 gene expression by 0.55-fold, which is the targetsite for the organophosphate and carbamate insecticides. This difference disappears when individuals are
exposed to both GBH and insecticide, suggesting an antagonistic effect. On the other hand, oxidative
status biomarker scores (PCAs of GPx, GR and CAT) were decreased when exposed to both stressors,
indicating a synergistic effect. Overall, we found that indirect GBH exposure can have both antagonistic
and synergistic effects in combination with an insecticide, which should be considered when aiming for
an ecologically relevant risk assessment of multiple human-induced stressors. | fi |
