“…We examined the serum enzyme activities of lysozyme and acid and alkaline phosphatase, which are frequently used as an indicator of innate immunity in other aquacultural animals. We also measured the expression of seven genes that are potentially related to temperature and immunity in the Chinese soft-shelled turtle (Dang et al, 2018). Lysozyme plays a crucial role in mediating protection against microbial invasion.…”

“…Seven genes, BCL6 , ARHGAP5 , RANGAP1 , NFAT5 , HNRNPK , TRAF3IP1 , and DLG1 , were selected and evaluated for their response to bacterial infection. These genes were identified by RNA‐seq quantification analysis in the liver of Chinses soft‐shelled turtles under different incubation temperatures (Dang et al, 2018). Two GAP proteins, ARHGAP5 and RANGAP, engage in signal transduction in multiple cell types (Bernards, 2003).…”

We mimicked daily fluctuations in temperature to examine whether the magnitude of the incubation temperature fluctuation affected the immunity of Chinese soft‐shelled turtle (Pelodiscus sinensis) hatchlings. The control incubation temperature was 29℃. Two of the temperatures used (29℃ ± 3℃ and 29℃ ± 5℃) were within the optimal range of the turtle's constant incubation temperature, and one (29℃ ± 9℃) was outside of this range. Data on hatching success, incubation period, and weight of the turtle hatchlings were collected. The incubation period and hatchling weight were significantly affected by temperature fluctuation, whereas the hatching success was not. After two months, the effect of the temperature fluctuation on hatchling weight was much more pronounced. After challenging hatchlings with pathogens, the hatchlings from the extremely fluctuating incubation temperature group were feeble. To explore the molecular changes of immunity associated with incubation temperature, serum lysozyme, acid and alkaline phosphatase activities, and seven immune‐related genes were examined in two‐month‐old turtles. Before pathogen infection, serum lysozyme activities were lower in turtles that experienced fluctuating temperature, and serum acid and alkaline phosphatase activities were higher in turtles exposed at 29℃ ± 3℃ and 29℃ ± 5℃. After pathogen challenge, lysozyme responded to the pathogen infection in 12 h, and acid and alkaline phosphatase activities were lower at 12 and 48 h in all four groups. Although the expression of the seven immune‐related genes was not affected before the bacterial challenge, they were upregulated after the bacterial challenge in all four groups.

The increase in temperature caused by global warming has greatly impacted plant growth and pest population dynamics worldwide, especially for wheat aphids. In this study, Sitobion miscanthi individuals from six geographic populations located in different wheat-producing areas in China were compared with regard to their growth, development, survival, and reproductive under different temperature conditions (17, 22 and 27°C). A population life-table analysis and a correlation analysis between geographic factors and S. miscanthi longevity or fecundity were also performed. Temperature significantly affected the nymphal development duration (NDD), the adult longevity (ALY) and the fecundity (AFY) of the aphids, however, latitude can only affect the NDD and ALY. There is an obvious interaction between temperature and latitude on the NDD, ALY, and AFY. The NDD in the three northern populations was significantly shorter than that in the southern populations. The ALY in northern populations was significantly longer than that in southern populations at different temperatures. Except for Yinchuan population was no significantly different under different degrees, the ALY of other populations was significantly shortened at 27°C. The AFY of northern populations was significantly lower than that of southern populations at 22°C, while significantly higher at 27°C. With the increase of temperature, the fecundity of northern population gradually decreased from 17 to 22°C, while the southern population suddenly decreased at 27°C. The curves of survival rate (sxj) in southern populations were significantly shorter than that of northern population. Especially the populations in Suzhou and Wuhan, in which the survival rate decreased rapidly at 27°C. Age-specific survival rate (lx) of southern populations began to decline rapidly on 15 days of age at 27°C, while those of northern populations were not significantly affected until on 20 days of age. The highest peaks of age-stage fecundity (fxj), age-specific fecundity (mx), and age-specific net maternity (lxmx) were occurred in northern populations. In addition, there was a positive correlation between latitude and longevity under the three degrees, however, only at 27°C, there was a positive correlation between latitude and fecundity. Our result proved that the higher reproductive rate of southern population requires aphids to live at the suitable ambient temperature, and aphid populations in the north have a wider ecological amplitude. The results will be helpful for predicting the potential aphid outbreaks in China’s main wheat areas under suitable conditions.
