昆虫发育起点温度估值的一种新方法
A NEW METHOD FOR ESTIMATING THE BASE TEMPERATURE OF THE INSECT DEVELOPMENT
【摘要】 本文提出一个运用优选法估计昆虫发育起点温度的简单方法。其目标函数是其中:ki=Ni(Ti-T0); n=温度处理数; T0=起点温度; Ni=第i个处理的平均历期; Ti=第i个处理的环境温度。 目标函数的最小值所对应的点T0即为起点温度的期望值。于是,相应的累积热单位K由下列方程所确定:
【Abstract】 This paper presents a simpler method for estimating the base temperature of the insect development by using the optimum seeking method. The objective function iswhere ki, =Ni(Ti-T0);n = the number of the temperature treatment;T0 = base temperature;N, = average duration of the ith treatment;T, = environmental temperature of the ith treatment.The point T0 which corresponds to the minimum of the objective function is the expected value of the base temperature. Thus, the corresponding accumulative heat unit K is determined by the equation as follows:
