摘　　要：We made separate experiments to examine life-history traits and activities of protective enzymes as affected by carbon dioxide(CO2)elevation to 780μL/L as compared to 390μL/L in imidacloprid-or buprofezin-resistant strains of the brown planthopper(BPH)Nilaparvata lugens.We found an interaction effect between resistance and the CO2 level on the nymphal survival and duration in both resistant strains.Nymphal durations in both resistant strains were much shorter in the resistant than susceptible BPH at 780μL/L but similar between them or slightly shorter in the resistant than susceptible BPH at 390μL/L.Nymphal survival was lower for imidacloprid-resistant than its susceptible BPH at 390μL/L but higher at 780μL/L;it stayed unaffected by the CO2 elevation in buprofezin-resistant BPH.We did not observe an interaction effect between resistance and the CO2 level on major reproductive parameters in both resistant strains.But the 2 strains were not consistent across CO2 levels in all parameters.Our measurements of protective enzyme activities of superoxide dismutase,catalase,and peroxidase showed an interaction between resistance and the CO2 level.Overall,these enzymes became similar in activity between resistant and susceptible BPH at 780μL/L compared to 390μL/L and the change was more distinct in the imidacloprid-than buprofezin-resistant BPH strains.Our findings suggest that CO2 elevation can affect life-history traits of insecticide-resistant BPH,while the effect may vary depending on the kind of insecticides it is resistant to.
