摘要
通过5种温度处理(19℃,22℃,25℃,28℃和31℃),探讨稻.卷叶螟实验种群的数量动态.25℃度温度处理组的世代存活率最高(19.7%),种群增长指数最大(14.9倍)。上述两项指标最低的是19℃温度处理组,分别为3.59b和1.18.根据实验结果,组建了该虫实验种群生命表,并建立了模拟种群数量变化的连续模型和等龄期结构的矩阵模型。
Fire temperature gradients(19℃, 22℃, 25℃, 28℃ and 31℃) were used to study the experimental population dynamics of rice leaf—roller.According to the results of experiment, the life table was developed.It was reported that the survival rate was the hightest in 25℃ condition, the generation survive rate and the population increasement rate are 19.7% and 14.9 respectively.Two models, contimus and discrete models were used to simulate the population dynamics and the results of simulation was fit to the observed values.
