利用正弦模型估算昆虫发育的有效积温

温度是影响昆虫发育速率及其发生期的重要生态因素,发育速率与温度的关系则常用有效积温法则来表示。阐述了利用直线回归法估算发育起点温度,利用蒙特卡罗模拟估算发育上限温度以及利用正弦模型计算变温条件下有效积温的方法,并编写了Matlab计算程序。同时,还利用该模型估算了白背飞虱发育的有效积温及其相应的发育历期,结果表明该程序计算结果与田间实际情况吻合。

Evaluation the Cumulative Temperature of Insect Using the Sine Wave Model

Temperature is a key ecological factor influencing the development rate of insects, the relationship between the development rate and the temperature usually was described using the law of cumulative temperature. The application of the method of the sine wave and the Monte Carlo simulation were described in this study. Moreover, a program of the Matlab was compiled. A brief introduction was made on how to use the linear regression method to estimate the compiled. Finally, the development duration of the method of the sine wave model was applied in the evaluation of the development cumulative temperature and the duration of white backed planthopper, and the result showed that the method of the sine wave model was useful to evaluate the cumulative temperature.
