Effect of thermal acclimation on the tolerance of the peach fruit fly (Bactrocera zonata: Tephritidae) to heat and cold stress

The effect of thermal acclimation on cold and heat tolerance of the peach fruit fly (<em>Bactrocera zonata</em>) was studied. Males and females were acclimated at 20, 25 and 30°C for up to 19 days following adult emergence. The critical thermal minimum (CT_min) and maximum (CT_max) were subsequently recorded as well adult survival following acute exposure to chilling (0 or -3°C for 2 hours). Additionally, the survival of pupae subjected for two hours to temperatures ranging from -12°C to 5°C was determined. The raw data collected during this study is available in the provided data file.本研究探究了热驯化对桃实蝇（<em>Bactrocera zonata</em>）耐寒性与耐热性的影响。研究选取刚羽化成虫（雌雄均包含），分别置于20℃、25℃及30℃环境中驯化，驯化时长最长可达19天。随后测定并记录其临界低温下限（CT_min）与临界高温上限（CT_max），同时检测成虫经0℃或-3℃急性低温暴露2小时后的存活率。此外，本研究还测定了蛹在-12℃至5℃的温度区间内经2小时暴露后的存活率。本研究采集的原始数据已收录于配套数据文件中。
