The salivary gland mRNA and protein datasets after diapause of the soybean hawkmoth, Clanis bilineata tsingtauica

The soybean hawkmoth, Clanis bilineata tsingtauica (CBT), is a major agricultural pest affecting soybean and other leguminous crops, but also has been explored as an edible insect resource in China and economically important for artificial rearing industry. Diapause, a stage-specific developmental arrest, is widely employed by insects to survive hostile seasonal conditions. Although significant progress has been made in understanding “diapause” in the context of insect physiology and evolutionary ecology, many questions remain unclear. In this study, we compared the salivary gland mRNA and protein profiles of fifth instar larvae in gluttonous and diapause stage respectively. A total of 2,194 genes showed significant differential expression between the two stages, while 1,746 proteins were identified in the proteome of diapause larvae. Integrating transcriptomic and proteomic data, we identified 172 genes with significant changes in expression, including 61 genes or proteins upregulated and 111 down-regulated during diapause. These datasets provide a valuable resource for identifying key genes and proteins, performing integrative omics analyses, and elucidating the regulatory mechanisms of diapause in CBT. This work advances our understanding of diapause regulation and support future studies on the molecular basis of insect diapause.
