Temperature plays a crucial role in shaping the biology of insects. Developmental temperature and acclimation temperatures influence their ability to cope with extreme thermal conditions. This study investigates the effects of developmental temperatures during the pupal stage and adult acclimation temperatures on the thermal tolerance of Linnaeus, 1758. We investigated cold tolerance based on chill-coma recovery time and heat tolerance based on heat knockdown time. Beetles were reared at five developmental temperatures (16, 21, 25, 30 and 35 °C) and later exposed to corresponding adult acclimation temperatures. From developmental temperatures of 21 and 30 °C, the group of beetles was subjected to different temperatures to induce adult acclimation at a different temperature than the developmental temperature. In cold-tolerance tests, beetles reared at lower temperatures showed better recovery from chill coma, while beetles reared at higher temperatures showed greater resistance to heat shock. Adult beetles acclimated to lower temperatures showed better cold tolerance, while those acclimated to higher temperatures performed better in the heat tolerance test. Interestingly, the developmental temperatures during the pupal stage also contributed to resistance, particularly in the heat-tolerance test. However, pupal stage temperatures had no effect on cold-shock resistance, as indicated by chill-coma recovery time. The results could provide insights into the rearing of
温度在塑造昆虫生物学特性方面起着至关重要的作用。发育温度和驯化温度会影响它们应对极端热条件的能力。本研究调查了蛹期发育温度和成虫驯化温度对1758年林奈所描述物种耐热性的影响。我们基于冷昏迷恢复时间研究耐寒性，基于热击倒时间研究耐热性。甲虫在五个发育温度（16、21、25、30和35°C）下饲养，随后暴露于相应的成虫驯化温度。从21和30°C的发育温度开始，该组甲虫被置于与发育温度不同的温度下进行成虫驯化。在耐寒性测试中，在较低温度下饲养的甲虫从冷昏迷中恢复得更好，而在较高温度下饲养的甲虫对热休克的抵抗力更强。适应较低温度的成年甲虫耐寒性更好，而适应较高温度的成年甲虫在耐热性测试中表现更佳。有趣的是，蛹期的发育温度也对抵抗力有影响，特别是在耐热性测试中。然而，如冷昏迷恢复时间所示，蛹期温度对冷休克抗性没有影响。这些结果可为……的饲养提供见解
