英文摘要	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 degrees C was 82.22 min. Rapid heat hardening for 1 h at 35 degrees C slightly increased CTmaxby 1.04 min but decreased it following exposure to 31 degrees C by 3.46 min and 39 degrees C by 6.78 min. Heat acclimation for 2 and 4 days significantly increased CTmaxat 35 degrees C by 1.83, and 6.83 min, respectively. Rapid cold hardening at 0 degrees C and 4 degrees C for 2 h, and cold acclimation at 10 degrees C for 3 days also significantly increased cold tolerance by 6.09, 5.82, and 2.00 min, respectively, while cold hardening at 8 degrees C for 2 h and acclimation at 4 degrees C and 10 degrees C for 5 days did not change cold stress tolerance. Mortality at 4 degrees 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.
