Ectotherms are sensitive to changes in ambient temperature that impact their physiology and development. To compensate for the effects of variation in temperature, ectotherms exhibit short or long-term physiological plasticity. An extensive body of literature exists towards understanding these effects and the solutions ectotherms have evolved. However, to what extent rearing temperature during early life stages impacts the behaviour expressed in adulthood is less clearly understood. In the present study, we aimed to examine the effects of developmental temperature on life-history traits and mating call features in a tropical field cricket, Acanthogryllus asiaticus. We raised A. asiaticus at two different developmental conditions: 25 °C and 30 °C. We found developmental time and adult lifespan of individuals reared at 30 °C to be shorter than those reared at 25 °C. Increased developmental temperature influenced various body size parameters differentially. Males raised at 30 °C were found to be larger and heavier than those raised at 25 °C, making A. asiaticus an exception to the temperature-size rule. We found a significant effect of change in immediate ambient temperature on different call features of both field-caught and lab-bred individuals. Developmental temperature also affected mating call features wherein individuals raised at higher temperature produced faster calls with a higher peak frequency compared to those raised at lower temperature. In addition, an interactive effect of both developmental and immediate temperature was found on mating call features. Our study highlights the importance of understanding how environmental temperature shapes life-history and sexual communication in crickets.

温度对蟋蟀生活史和交配叫声的影响

变温动物对影响其生理和发育的环境温度变化很敏感。为了补偿温度变化的影响,变温动物表现出短期或长期的生理可塑性。存在大量文献来了解这些影响,并且解决方案已经演变。然而,早期生活阶段的饲养温度在多大程度上影响成年期表现的行为尚不清楚。在本研究中,我们旨在研究发育温度对热带蟋蟀 Acanthogryllus asiaticus 生活史特征和交配呼叫特征的影响。我们在两种不同的发育条件下饲养了 A. asiaticus:25 °C 和 30 °C。我们发现在 30 °C 下饲养的个体的发育时间和成年寿命比在 25 °C 下饲养的个体短。增加的发育温度对各种体型参数有不同的影响。发现在 30 °C 饲养的雄性比在 25 °C 饲养的雄性更大更重,这使得 A. asiaticus 成为温度大小规则的一个例外。我们发现即时环境温度的变化对野外捕获和实验室培育的个体的不同呼叫特征有显着影响。发育温度也影响交配呼叫特征,其中与在较低温度下饲养的个体相比,在较高温度下饲养的个体产生具有更高峰值频率的更快的呼叫。此外,还发现了发育温度和即时温度对交配呼叫特征的交互影响。
