Abstract

Extreme temperatures threaten species under climate change and can limit range expansions. Many species cope with changing environments through plastic changes. This study tested phenotypic changes in heat and cold tolerance under hardening and acclimation in the melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae), an agricultural pest of many vegetables. We first measured the critical thermal maximum (CTmax) of the species by the knockdown time under static temperatures and found support for an injury accumulation model of heat stress. The inferred knockdown time at 39 °C was 82.22 min. Rapid heat hardening for 1 h at 35 °C slightly increased CTmax by 1.04 min but decreased it following exposure to 31 °C by 3.46 min and 39 °C by 6.78 min. Heat acclimation for 2 and 4 days significantly increased CTmax at 35 °C by 1.83, and 6.83 min, respectively. Rapid cold hardening at 0 °C and 4 °C for 2 h, and cold acclimation at 10 °C for 3 days also significantly increased cold tolerance by 6.09, 5.82, and 2.00 min, respectively, while cold hardening at 8 °C for 2 h and acclimation at 4 °C and 10 °C for 5 days did not change cold stress tolerance. Mortality at 4 °C for 3 and 5 days reached 24.07 % and 43.22 % respectively. Our study showed plasticity for heat and cold stress tolerance in T. palmi, but the thermal and temporal space for heat stress induction is narrower than for cold stress induction.

硬化和适应性诱导瓜蓟马对冷热胁迫耐受性的可塑性
极端温度威胁着气候变化下的物种,并可能限制其分布范围的扩大。许多物种通过可塑性变化来应对不断变化的环境。本研究测试了瓜蓟马(Thysanoptera: Thripidae)在硬化和适应环境下耐热和耐寒的表型变化。我们首先通过静态温度下的击倒时间测量了该物种的临界最大热量(CTmax),发现该模型支持热胁迫的伤害累积模型。在 39 °C的温度下,推断的击倒时间为 82.22 分钟。在 35 °C 下快速热硬化 1 小时可使 CTmax 稍微增加 1.04 分钟,但暴露于 31 °C 和 39 °C 下则分别减少了 3.46 分钟和 6.78 分钟。热适应 2 天和 4 天可显著提高 35 °C 时的 CTmax,分别提高 1.83 分钟和 6.83 分钟。在 0 °C 和 4 °C 下快速冷冻 2 小时以及在 10 °C 下冷藏 3 天也能显著提高耐寒性,分别提高了 6.09 分钟、5.82 分钟和 2.00 分钟,而在 8 °C 下冷冻 2 小时以及在 4 °C 和 10 °C 下冷藏 5 天不会改变耐寒性。4 °C 3 天和 5 天的死亡率分别为 24.07 % 和 43.22 %。我们的研究表明,棕榈蓟马对热和冷胁迫的耐受性具有可塑性,但热胁迫诱导的热空间和时间空间比冷胁迫诱导的要窄。

期刊介绍: All aspects of insect physiology are published in this journal which will also accept papers on the physiology of other arthropods, if the referees consider the work to be of general interest. The coverage includes endocrinology (in relation to moulting, reproduction and metabolism), pheromones, neurobiology (cellular, integrative and developmental), physiological pharmacology, nutrition (food selection, digestion and absorption), homeostasis, excretion, reproduction and behaviour. Papers covering functional genomics and molecular approaches to physiological problems will also be included. Communications on structure and applied entomology can be published if the subject matter has an explicit bearing on the physiology of arthropods. Review articles and novel method papers are also welcomed.
