高温胁迫对灰茶尺蠖生命参数及保护酶活性的影响
Effects of High Temperature on Lifespan,Fecundity,and Protective Enzymes of Ectropis grisescens
摘要
Abstract
[Objective]Resistance and response to high temperatures of the antioxidants in Ectropis grisescens were studied.[Method]Lifespan and fecundity of adult E.grisescens Warren after being exposed to 30℃,35℃,38℃or 41℃for 1 h or 44℃for 3 min were observed according to measurements on the egg hatchability and total protein content and activities of superoxide dismutase(SOD),catalase(CAT),and peroxidase(POD)as well as total antioxidant capacity(T-AOC)in the insects.[Result]The increased temperature significantly shortened the lifespan,decreased the female oviposition,and lowered the egg hatchability of E.grisescens.At 41℃and 44℃,the egg ceased to hatch.The maximum total protein contents in the female and male adults differed significantly under different temperatures—it was under 35℃for the females and 38℃for the males.The SOD activity in the female adults changed in an upside-down V pattern as the temperature rose,while that in the male adults was low at 41℃.In the female adults the highest CAT activity occurred at 44℃,the T-AOC decreased with increasing temperature,and the POD rose with rising temperature,whereas those in the male adults exhibited a low-high-low trend in the temperature range.[Conclusion]The protective enzymes in E.grisescens Warren played a key role in how the insect adapted to high temperature stress.关键词
