研究了腐食酪螨在5个温度梯度下的实验种群生命表。结果表明,在12.5℃和30℃时,该种群的瞬时增长力和周限增长率均较小,分别为0.0556、1.0572和0.0568、1.0585。说明温度过低或过高,均不利于该螨的发育繁殖。20℃虽然世代净生殖率最高,但由于产卵时间较长,平均日产卵量较少,瞬时增长力也较小。25℃时,该种群的存活率最高(0.7292),瞬时增长力和周限增长率最大(0.2638和1.3019),日均产卵量最多,达21.87粒。
The life table of experimental populations of Entomoides mongolicum under five temperature gradients was studied. The results showed that at 12.5 ℃ and 30 ℃, the instantaneous growth force and the growth rate of the population were all smaller, which were 0.0556, 0.0572 and 0.0568, 1.0855 respectively. Indicating that the temperature is too low or too high, are not conducive to the development and reproduction of the mite. Although the net generation rate of 20 generations is the highest in the generation, the average growth rate is also small due to the longer spawning time and less average fecundity per day. At 25 ℃, the highest survival rate (0.7292), the instantaneous growth rate and the maximum growth rate (0.2638 and 1.3019), the average daily fecundity was 21.87.
