Here, we investigated the physiological responses of adult beet webworm, <jats:italic>Loxostege sticticalis<\/jats:italic> L.

Transcriptome analysis revealed that vitellogenin (VG) and vitellogenin receptor (VR) genes were up\u2010regulated at 30\u2009\u00b0C, as were numerous genes related to energy metabolism, including those involved in the insulin signaling pathway, the tricarboxylic acid (TCA) cycle, and glycolysis. Expression of the trehalose transporter gene <jats:italic>TRET1<\/jats:italic> was also induced at high temperature, primarily in the ovaries, where trehalose content increased, accompanied by lipid degradation in the fat body. Treatment with the trehalase inhibitor validamycin A reduced female fecundity and longevity at 23\u2009\u00b0C, but enhanced the expression of genes related to stress resistance and reproduction, mimicking the effect of high temperature.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Besides their practical utility for predicting the oviposition behavior and
