摘要: 阐述了昆虫物候分析的SSPM模型(single sine phonological model)计算方程和过程,该模型采用Sine函数拟合每天温度变化,并利用积分,获取每天有效积温和一定时间内日度累积值。SSPM重要的参数有发育起点温度和上限温度,参与模型计算包括日最高气温和日最低气温2个输入值,在输入值和参数值组合条件下,模型有6个不同计算方程。以棉铃虫(Helicoverpa armigera)为例,介绍了SSPM在昆虫发育历期分析过程,简单表述了模型预测功能。随自动化气象站分布密度增加和Internet技术的发展,模型在区域化害虫管理中有着重要的应用前景。

Abstract: The paper details the calculation method of single sine phonological model(SSPM) in insect phenology,in which the daily temperature is curved by sine function.Accumulations and daily degree-days are acquired by integral equation methods.Two parameters,low temperature threshold and upper temperature threshold,and two input values,daily minimum and maximum temperature are applied in degree-days calculation.There were six equations under combination of those parameters.Taking cotton bollworm(Helicoverpa armigera) for instance,the calculation and prediction process of SSPM are clarified in insect phenology.With the development of the Internet and automation weather station,SSPM have more prospective application in regional pest management.
