| 摘 要： | 在15、20、25、28、31、34℃的恒温条件下，测定了苹果蠹蛾Cydiapomonella（L．）各发育历期、存活率及产卵量，组建了苹果蠹蛾实验种群生命表，以探讨温度对苹果蠹蛾生长发育和繁殖的影响。在15～31℃范围内，苹果蠹蛾各阶段发育历期随温度的升高而缩短，世代平均发育历期在15、20、25、28、31℃时分别为112．0、46．8、33．3、29．6、26．2天；在34℃时，苹果蠹蛾发育受阻，世代平均发育历期延长为31．4天。成虫寿命亦随温度的升高而缩短；单雌平均产卵量在25℃时最高，为92．7粒；在15和34℃条件下，没有有效卵产生。生命表分析显示，种群趋势指数（I）在20～31℃时均大于1，25℃时苹果蠹蛾种群内禀增长率（rm）和种群趋势指数最高，分别为0．0972和39．70。研究表明，25℃左右是苹果蠹蛾生长发育和繁殖的适宜温度，温度过高或偏低均不利于苹果蠹蛾的生长繁殖。

| Abstract: | In order to explore the influence of temperature on the development and reproduction of codling moth,Cydia pomonella(L.),the developmental duration,survivorship,and fecundity of this pest were investigated in the laboratory under 15,20,25,28,31 and 34℃,and then constructed life tables of the experimental population of codling moth at different temperatures.The developmental durations decreased with the temperature increasing from 15℃ to 31℃,the developmental duration for the whole generation at 15,20,25,28,31℃ was 112.0,46.8,33.3,29.6,26.2 days,respectively.The development of codling moth was inhibited at 34℃,the developmental duration for the whole generation increased to be 31.4 days.Adult lifespan decreased with the temperature increasing.The maximum number of eggs laid per female was 92.7 at 25℃,oviposition of fertile eggs failed at 15 and 34℃.The analysis of life table showed that population trend index(I) were larger than 1 at 20-31℃,the intrinsic rate of increase(rm) and population trend index were the highest at 25℃,with the values being 0.0972 and 39.70,respectively.The results showed that the most suitable temperature for this pest was 25℃ or so,when temperature was too high or low,it was detrimental to reproducing of codling moth. |
