随着气候变化对外来入侵物种的积极影响越来越大，预计生物入侵将更加频繁。入侵昆虫在不同温区的成功与它们对极端温度的耐受性密切相关。本研究以一种外来的蕾丝虫（Corythucha ciliata）为研究对象，探讨了从温带入侵亚热带的昆虫具有较高的生存和高温适应能力，其耐热性在其季节丰度和地理分布中起重要作用的假设。为了验证这些假设，在实验室中评估了热休克对毛纤毛虫成虫存活和繁殖的影响。成人分别在26（对照）、35、37、39、41、43和45℃下暴露2小时，然后转移到26℃。35 ~ 41℃的热休克温度对成虫的存活模式、寿命和繁殖力没有显著影响，但43和45℃的热休克显著降低了这些特征。35 ~ 41℃的热激处理对卵的孵化率、若虫存活率和雌f1后代比例无显著影响，而43和45℃的热激处理均无后代产生。结果表明，纤毛藓能耐受低于41°C的高温，这可能是其在寄主Platanus树种广泛分布的中国低纬度地区扩张的原因。本研究结果对预测气候变化下的季节丰度和了解这一重要城市入侵者的入侵机制具有重要意义。
Biological invasions are predicted to be more frequent as climate change is increasing its positive impact on the prevalence of invasive exotic species. Success of insect invaders in different temperature zones is closely related to their tolerance to temperature extremes. In this study, we used an exotic lace bug (Corythucha ciliata) as the study organism to address the hypotheses that an insect species invading a subtropical zone from temperate regions has a high capacity to survive and adapt to high temperatures, and that its thermal tolerance plays an important role in determining its seasonal abundance and geographic distribution. To test these hypotheses, the effects of heat shock on the survival and reproduction of C. ciliata adults were assessed in the laboratory. Adults were exposed to 26 (control), 35, 37, 39, 41, 43, and 45°C for 2 h, and then were transferred to 26°C. Heat-shock temperatures ranging from 35 to 41°C did not significantly affect survival pattern, longevity, and fecundity of adults, but heat shock at 43 and 45°C significantly reduced these traits. Exposing parent females to heat-shock treatments from 35 to 41°C did not significantly affect the hatching rate of their eggs, survival of the nymphs, and the proportion of female F 1 progeny, while no progeny were produced with treatments of 43 and 45°C. The results indicate that C. ciliata can tolerate high temperatures less than 41°C, which may contribute to its expansion into the lower latitudes in China where its hosts (Platanus trees) are widely planted. Our findings have important implications for predicting seasonal abundance and understanding invasion mechanisms of this important urban invader under climate change.
