“…Although C. ciliata is able to survive, develop, and reproduce over a wide range of temperatures (Ju et al., 2011a), our results show that the increasing duration of exposure to temperatures above 41 °C resulted in a significant decrease in the survival of eggs, nymphs, and adult females and males. Lethal temperatures for 50% of all stages of C. ciliata were between 41 and 44 °C for 2 h. Similarly, Ltemp 50 of the codling moth, Cydia pomonella (L.), is 44 °C for 2 h (Chidawanyika & Terblanche, 2011).…”

“…Corythucha ciliata , however, can suffer from extensive pre‐freeze mortality, suggesting that the supercooling point (SCP) is a poor indicator of cold hardiness in this species and, that C. ciliata is a freeze‐intolerant species (Ju et al., 2010). Nevertheless, rapid cold hardening may help C. ciliata survive the acute low temperatures that may occur in early winter and spring (Ju et al., 2011b). The heat tolerance of C. ciliata , however, has not been investigated in depth.…”

“…The effect of exposure duration at each temperature and the effect of heat hardening on survival were determined by one‐way analysis of variance (ANOVA), and the means were compared using Tukey’s test (Ju et al., 2011a,b). Multivariate analysis of variance (MANOVA) was used to test interactions of stage*temperature, stage*time, temperature*time, and stage*temperature*time.…”

The sycamore lace bug, Corythucha ciliata (Say) (Hemiptera: Tingidae), is an invasive exotic pest on Platanus trees in China. This study assessed the thermotolerance of C. ciliata in the laboratory. Detailed experiments were conducted on the effects of high temperature (35, 37, 39, 41, 43, and 45 °C), duration of exposure (0.5, 1, 2, 4, 6, and 8 h), and developmental stage (egg, nymph, and adult) on survival of the bug. Meanwhile, the effects of heat hardening on survival at lethal temperature (exposure to 33, 35, 37, 39, and 41 °C for 1 h prior to transfer to 43 °C for 2 h) were also assessed for nymphs and adults. Survival of eggs, nymphs, and adults was not affected by temperatures between 35 and 39 °C, but declined rapidly with increasing duration of exposure (from 0.5 to 8 h) at temperatures ≥41 °C. The lethal temperature that caused mortality of 50% (Ltemp50) of all developmental stages decreased with increasing duration of exposure from 0.5 to 8 h. The Ltemp50 for nymphs was 44.3, 42.0, and 39.0 °C after 0.5, 2, and 8 h exposure, respectively. Thermotolerance was the highest in eggs, followed by adults and then nymphs. Thermotolerance was slightly greater for adult males than for adult females. The ability of nymphs, females, and males to survive exposure to 43 °C for 2 h significantly increased by heat hardening, i.e., by exposure to a non‐lethal high temperature for 1 h; the optimal heat‐hardening temperature was 37 °C. The results indicate that survival of C. ciliata at heat‐shock temperatures depended on both the temperature and the duration of exposure, and the tolerance to heat shock was enhanced by heat hardening. The thermotolerance of C. ciliata may partially explain why C. ciliata has been rapidly spreading on Platanus trees in southern provinces of China.

“…In China, C. ciliata was first found in Hunan Province in 2002 and then spread to 11 other provinces between latitudes 26°N and 37°N over the last decade [28]. C. ciliata has caused the most damage in subtropical China, particularly in the Yangtze basin, where it has infested almost 70% of host trees [29], [30]. C. ciliata is an oligophagous insect with a short life cycle, and its hosts ( Platanus spp.)…”

“…Because Platanus trees are widely planted in China, the spread of this pest will not be limited by host availability but might depend on its ability to adapt to environmental conditions, especially to temperature. Despite previous work on cold tolerance of C. ciliata [28], [30] and other effects of temperature on this species [12], [29], there is generally a lack of quantitative data on how its reproduction and fitness are affected by high temperatures.…”

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.

The red imported fire ant (RIFA), Solenopsis invicta Buren is native to South America and known as a global problematic invasive species. At low temperatures, several investigations have demonstrated an increase in glycerol as a primary rapid cold hardening (RCH) component and an increase in the supercooling point. Two genes, glycerol-3-phosphate dehydrogenase (GPDH) and glycerol kinase (GK), have been identified as being involved in the glycerol production process. In this study, one GPDH and two GK sequences were extracted from RIFA transcriptome analysis (Si-GPDH, Si-GK1, and Si-GK2). All three genes were expressed in different body parts and different tissues of S. invicta that Si-GK2 showed a higher expression level than the others. According to gene expression levels by qRT-PCR analysis, the highest expression levels of three genes were observed in fat body tissues. After 1 h of exposure to low temperatures (5°C or lower), the mRNA levels of these genes significantly increased, according to expression analyses. RNA interference (RNAi) of Si-GPDH or Si-GK1 and Si-GK2 exhibited a significant downregulation at the mRNA level. The mortality rate of treated RIFA by double-stranded RNA (dsRNA) specific to GPDH and GK2 significantly increased at low temperatures. This study indicates that GPDH and GK2 as glycerol biosynthesis genes in RIFA have a high expression
