Abstract
The response of insects to stress, particularly starvation and high temperature stress, is a crucial area of insect research. Uridine diphosphate-glucosyltransferases (UGTs) are key enzymes involved in the detoxification of exogenous substances. This study analyzed the role of the UGT344J7 gene in the response of Rhopalosiphum padi to starvation and high temperature stress. UGT344J7 was significantly upregulated under conditions of high temperature and food scarcity. Following RNAi targeting UGT344J7, the mortality of R. padi increased significantly under both high temperature and starvation conditions. Knockdown of the UGT344J7 gene led to a significant increase in reactive oxygen species (ROS) levels in R. padi, accompanied by a significant downregulation of four heat shock protein genes (Hsp70-1, Hsp70-2, Hsp68, Hsp90). Based on these results, we speculate that UGT344J7 regulates the expression of heat shock protein genes by modulating ROS levels, thereby helping R. padi cope with high temperature and starvation stress. This is the first report on the role of the UGT gene in starvation and high temperature stress in an aphid species. This research suggests that silencing UGT344J7 could serve as a potential strategy for controlling R. padi, and novel insecticides targeting this gene may be developed to disrupt the physiological processes of this significant pest.
We have submitted the raw data and processed data for Figure1 (Relative expression levels of UGT344J7), Figure2 (RNA interference efficiency), Figure3 (Mortality of R. padi under different treatments), Figure4 (Relative expression levels of Hsp genes), Figure5 (The ROS content), FigureS1 (The relative expression of 43 UGT genes after prolonged high temperature treatment), FigureS2 (Mortality under normal conditions following injection of dsRNA). We mainly used RT-qPCR, RNAi interference, and ELISA to study the role of UGT344J7 in the response of the bird cherry-oat aphid to starvation and high temperature stress. The following is a description of the data set.

Data brief description: In Figure 1, we treated aphids with temperature and starvation, and then measured the relative expression of UGT344J7 gene after different treatments. The detection method used was RT-qPCR. Each treatment had three mechanical and three biological replicates. The ct value is the original data detected by the instrument. After calculation by the formula, 2-∆∆Ct is obtained. We calculated the relative expression of the target gene according to the 2-∆∆Ct. We selected EF-1a and β-actin as internal reference genes.
Ct: The number of threshold cycles, the number of cycles experienced when the fluorescence signal in each reaction tube reaches the set threshold.
2-∆∆Ct: The gene expression level change of the treatment group relative to the control group.
The naming of different treatments is as follows:

C3: When the treatment conditions were Starvation treatment for 24h and 24-h starvation and 24-h refeeding, the corresponding control group. C4: When the treatment conditions were Starvation treatment for 48h and 48-h starvation and 24-h refeeding, the corresponding control group.)

At the same time, the mortality of aphids treated with temperature and starvation after interference with UGT344J7 was also detected.

We sinusoidally convert the mortality rate and then perform a significance analysis.
