Models were developed to describe the effects of heating rate during heat treatments on the mortality of 5th-instar codling moth, Cydia pomonella (L.). An old model, developed from previous studies over a limited range of heat treatments, was 1st formulated. Subsequent heat treatments, using a computerized water bath system and linear heating rates of 4, 6, 8, 10, and 12 degrees C/h at 42, 44, and 46 degrees C, were used to test the old model. The mortality data from the water bath study were used to develop a new model. Although the old model provided a good estimate of the effects of heating rate on 5th-instar mortality, it overestimated mortality at midrange heating rates. Also, the old model was awkward to use because it required a correction for each treatment temperature. The new model incorporated treatment temperature into the equation, and was more accurate and easier to use. It was determined that the slower the rate of heating, the longer the exposure to the final treatment temperature was needed to achieve 95% mortality.
建立了模型以描述热处理过程中的加热速率对苹果蠹蛾(Cydia pomonella (L.))五龄幼虫死亡率的影响。首先构建了一个旧模型,该模型是基于之前在有限热处理范围内的研究得出的。随后,使用计算机控制的水浴系统,在42℃、44℃和46℃下以4、6、8、10和12℃/小时的线性加热速率进行后续热处理,以检验旧模型。水浴研究中的死亡率数据被用于建立一个新模型。尽管旧模型对加热速率对五龄幼虫死亡率的影响提供了较好的估计,但它高估了中等加热速率下的死亡率。此外,旧模型使用起来很不方便,因为它需要对每个处理温度进行校正。新模型将处理温度纳入方程,更加准确且易于使用。结果表明,加热速率越慢,达到95%死亡率所需暴露于最终处理温度的时间就越长。
