摘要

摘要: 目的探讨温度对灰茶尺蛾（Ectropis grisescens）实验种群生命表参数的影响。方法设置5种温度处理（19 ℃、22 ℃、25 ℃、28 ℃和31 ℃），构建灰茶尺蛾实验种群生命表。结果温度影响灰茶尺蛾的个体生长发育，卵-成虫的发育历期随温度升高而逐渐缩短，31 ℃下发育历期最短（27.6 d）。不同温度对灰茶尺蛾成活率有显著的影响，5种温度处理下，灰茶尺蛾成活率在22 ℃处理下最高（64.0%）。种群生命表结果表明，与其他4 种温度处理相比，25 ℃处理下灰茶尺蛾的种群净增殖率（R₀）最高，达到90.88后代/个体，且内禀增长率（r）和周限增长率（λ）在25 ℃处理下也最高，分别为0.126 d⁻¹和1.134 d⁻¹。结论 25 ℃是灰茶尺蛾个体生长和种群增长的最适温度，可为灰茶尺蛾的室内饲养、田间种群发生预测预报及综合防治提供数据参考。

Abstract: Objective The effect of temperature on life table parameters of Ectropis grisescens were measured. Method In this study, five temperatures (19 ℃, 22 ℃, 25 ℃, 28 ℃ and 31 ℃) treatments were set up to analysis the life table parameters of E.grisescens. Result The results showed that temperature can affect the growth and development of E. grisescens, and the developmental period from egg to adult decreased as temperature increasing, the shortest developmental period (27.6 d) of E. grisescenswas observed at 31 ℃. Different temperature had significant effect on survival rate of E. grisescens, the higher survival rate (64.0%) of E. grisescens was found at 22 ℃ compared with other temperature treatments. Temperature had a significant effect on the life table parameters of E. grisescens population. Significantly, higher net reproductive rate (R₀) of E. grisescens population was found at 25 ℃ compare with other temperature treatments and R₀ was up to 90.88 offsprings per individual. The intrinsic rate of increase (r) and the finite rate of increase (λ) were also the highest at 25 ℃, which was 0.126 d⁻¹ and 1.134 d⁻¹, respectively. Conclusion The results of this study indicated that 25 ℃ was the optimum temperature for the population growth of E. grisescens, which provided a scientific basis for indoor rearing, field population occurrence prediction and integrated control of this insect pest.
