Spodoptera exigua(Lepidoptera: Noctuidae) larvae were used to analyze the regulation of lipid, protein and carbohydrate metabolism in host larvae infected with the Heliothis virescens ascovirus 3h (HvAV-3h). Using histological sections, significant pathological changes were found in the fat bodies of infected larvae from 24 h to 72 h post-infection (hpi). The lipid and protein contents of the infected larvae were significantly higher than those of the uninfected larvae, while the carbohydrate content of the infected larvae was significantly lower than that of the mock-infected larvae. The selected primary metabolite metabolism-associated genes showed different expression patterns. Further co-relationship analysis of the gene expression level and content changes of primary metabolites indicated the following: the acyl-CoA dehydrogenase and fatty acid synthase genes were closely associated with lipid metabolism, and the hexokinase and the glycogen synthase gene expression levels were related to carbohydrate metabolism, while the aminopeptidase N and the protein disulfide isomerase gene expression levels were not correlated with protein metabolism. These results indicate that the HvAV-3h virus stimulates host larval lipid and protein syntheses and inhibits carbohydrate synthesis.
