摘要： Trichoderma spp. are widely used in agriculture as biofungicides. In this study, effects of elevated CO2 on the growth and enzyme activities of Nilaparvata lugens infected by T. asperellum were studied. The results showed that fecundity of N. lugens adversely decreased under elevated CO2 relative to ambient CO2 irrespective of infection with T. asperellum. The contents of protein and alkaline phosphatase significantly decreased in N. lugens nymphs with T. asperellum infection under elevated CO2 relative to ambient CO2. Significantly higher activities of carboxylesterase and acetylcholinesterase were observed in N. lugens infested with T. asperellum under elevated CO2 compared with ambient CO2. While significantly lower catalase and glutathione S-transferase were observed in N. lugens nymphs infested by T. asperellum under elevated CO2 relative to ambient CO2. Measuring the antioxidases and detoxification enzymes in N. lugens infected with T. asperellum can partly explain the response of fitness parameters of N. lugens under elevated CO2.
