Fifth-instar codling moth, Cydia pomonella (L.), larvae were exposed to 10 simulated heat treatments of apples and pears and CO2 levels were monitored as a measure of respiration. Marked increases in respiration rates (microliter CO2/mg/min) were noted during these treatments. Respiration peaked between 3.5 and 4.8 microliters CO2/mg/min; the amount of time to peak respiration depended on the heating rate and was correlated to the LT95. No differences were observed between male and female larvae in the timing of the peaks of CO2 production. In treatments where mortality occurred, CO2 levels dropped to zero, but only after a considerable time after death. Respiratory recovery rates, the time it took for CO2 levels to return to normal, were recorded after treatments at time points where CO2 production reached 3/4 and maximum peak. Respiration rates at constant temperatures were recorded within the range of 10-30 degrees C. Q10 over this range was 1.49, whereas Q10 was the greatest, 2.54, between 10 and 15 degrees C.
将五龄苹果蠹蛾,即苹果小卷蛾(Cydia pomonella (L.))幼虫置于10种模拟的苹果和梨热处理环境中,并监测二氧化碳水平以衡量呼吸作用。在这些处理过程中,观察到呼吸速率(微升二氧化碳/毫克/分钟)显著增加。呼吸作用在3.5至4.8微升二氧化碳/毫克/分钟之间达到峰值;达到呼吸峰值的时间取决于加热速率,且与LT95相关。在二氧化碳产生峰值的时间方面,未观察到雄性和雌性幼虫之间存在差异。在出现死亡的处理中,二氧化碳水平降至零,但仅在死亡后的相当长时间之后。在二氧化碳产生达到3/4峰值和最大峰值的时间点进行处理后,记录了呼吸恢复速率,即二氧化碳水平恢复正常所需的时间。在10至30摄氏度范围内记录了恒温下的呼吸速率。在此温度范围内,Q10为1.49,而在10至15摄氏度之间,Q10最大,为2.54。
