Abstract

Under natural environmental conditions, insects are highly affected by heat stress. Studies on the effect of heat stresses on the life history of Dysdercus koenigii are scarce. This study investigated the effect of short-term high temperature stress on the developmental period, survival rate of all stages and reproduction of D. koenigii adults. Eggs, nymphs and adults were exposed to 28 °C, 31 °C, 34 °C, 37 °C and 40 °C for 2 h and returned to the laboratory to check all the above-mentioned aspects. The developmental duration and survival rate of all stages decreased with the increase of temperature. Longevity and survival rate of females were significantly higher than males after exposure to heat. Fecundity and hatching percentage was significantly decreased with the increase of temperature. Because short-term high temperature stress response is vital for the survival of all stages of D. koenigii, our findings can be used to develop a more profound understanding of the potential for this insect to evolve in response to environmental changes.

温度波动对柯尼霉某些生物学参数的影响
在自然环境条件下,昆虫受热应激的影响较大。关于热胁迫对柯尼霉生活史影响的研究很少。本文研究了短期高温胁迫对柯尼氏夜蛾成虫发育期、各期存活率和繁殖的影响。卵、若虫和成虫分别在28°C、31°C、34°C、37°C和40°C环境中暴露2 h后返回实验室进行上述检查。各阶段的发育期和成活率均随温度的升高而降低。受热后雌虫的寿命和存活率显著高于雄虫。随着温度的升高,产卵率和孵化率显著降低。由于短期高温胁迫反应对柯尼氏夜蛾所有阶段的生存都至关重要,我们的发现可以用来更深入地了解这种昆虫对环境变化的进化潜力。
