dc.description.abstract<p>Temperature is a crucial driver of insect activity and physiological processes throughout their life-history, and heat stress may impact life stages (larvae, pupae and adult) in different ways. Using thermolimit respirometry, we assessed the critical thermal maxima (CT<sub>max</sub>-temperature at which an organism loses neuromuscular control), CO<sub>2</sub> emission rate (V́CO<sub>2</sub>) and Q10 (a measure of V́CO<sub>2</sub> temperature sensitivity) of three different life stages of <i>Helicoverpa punctigera</i> (Wallengren) by increasing their temperature exposure from 25 <sup>o</sup>C to 55 <sup>o</sup>C at a rate of 0.25 <sup>o</sup>C min<sup>-1</sup> . We found that the CT<sub>max</sub> of larvae (49.1 <sup>o</sup>C ± 0.3 <sup>o</sup>C) was higher than pupae (47.4 <sup>o</sup>C ± 0.2 <sup>o</sup>C) and adults (46.9 <sup>o</sup>C ± 0.2 <sup>o</sup>C). The mean mass-specific CO<sub>2</sub> emission rate (ml V́CO<sub>2</sub> h<sup>-1</sup>) of larvae (0.26 ± 0.03 ml V́CO<sub>2</sub> h<sup>-1</sup>) was also higher than adults (0.24 ± 0.04 ml V́CO<sub>2</sub> h<sup>-1</sup>) and pupae (0.06 ± 0.02 ml V́CO<sub>2</sub> h<sup>-1</sup>). The Q<sub>10</sub>: 25-35 <sup>o</sup>C for adults (2.01 ± 0.22) was significantly higher compared to larvae (1.40 ± 0.06) and Q<sub>10</sub>: 35-45 <sup>o</sup>C for adults (3.42 ± 0.24) was significantly higher compared to larvae (1.95 ± 0.08) and pupae (1.42 ± 0.98) respectively. We have established the upper thermal tolerance of <i>H. punctigera</i>, which will lead to a better understanding of the thermal physiology of this species both in its native range, and as a pest species in agricultural systems.</p>en
