温湿度对烟草粉螟实验种群的影响

Effect of Temperature and Humidity on Laboratory Population of Ephestia elutella Hübner

摘要: 在相对湿度85%及温度15、20、25、30℃情况下对烟草粉螟Ephestia elutella Hübner)实验种群特定年龄生命表进行系统研究，获得了世代平均周期T、净生殖率R0、内禀增长率rm、种群倍日数t、种群趋势指标I共5种生命表参数，及不同温度下烟草粉螟卵的发育历期和孵化率、各龄的历期、成虫的寿命与产卵量等，并进行了分析。

Abstract: In this paper,five life table parameters (length of generation,net productive rate,innate capacity for increase,population trend index and days for population to double) were obtained by studying the agespecific life table of the laboratory population of Ephestia elutella Hübner,under the conditions of 4 temperatures (15,20,25,30℃) combined with relative humidity 85%.We also studied the effects of temperature and relative humidity on adult longevity,survival rate,development time,fertility and hatching rate.
