LED光照对灰茶尺蠖成虫保护酶活性的影响
Effects of LED light on the activities of protective enzymes in Ectropis grisescens(Lepidoptera:Geometridae)adults
摘要
Abstract
[Aim]To study the effects of wavelength,intensity and treatment time of LED light on the activities of protective enzymes in Ectropis grisescens adults,so as to provide references for the green control of E.grisescens with light in tea garden.[Methods]The female and male adults of E.grisescens were exposed to LED light at the wavelengths of 590-595 and 520-525 nm under the light intensities of 40,80 and 120 lx,respectively,in the laboratory,and the changes in the total protein content,activities of protective enzymes[peroxidase(POD),superoxide dismutase(SOD)and catalase(CAT)],and total antioxidant capacity(T-AOC)were tested at 1,2 and 3 h after treatments.[Results]After exposure to LED light at the wavelengths of 590-595 and 520-525 nm,the total protein content,the activities of POD,SOD and CAT,and T-AOC in female and male adults of E.grisescens increased with the increase of light intensity and treatment time.At different time after exposure to LED light at the two wavelengths under various light intensities,the total protein content and POD activities in female adults were significantly higher than those in male adults,and the activities of SOD and CAT,and T-AOC in male adults were higher than those in female adults and those in female and male adults at 3 h under LED light intensity of 120 lx were the highest.The activities of POD,SOD and CAT in female and male adults of E.grisescens subjected to LED light radiation at the two wavelengths for different time was higher than those in the natural light control.[Conclusion]LED light at the wavelengths of 590-595 and 520-525 nm can cause changes in the protective enzyme activities in E.grisescens adults,providing basic data for exploring the best wavelength,intensity and time of breaking protective enzyme activity and green control using light to irradiate pests in tea garden.关键词
