title: Role of UGT344J7 in the response of the bird cherry-oat aphid to starvation and high temperature stress

description: 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.

 starvation and high temperature stress** [Access this dataset on
 Dryad](https://doi.org/10.5061/dryad.02v6wwqfw) 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
