Application of gene expression of insulin signaling pathway to insect growth modeling

초록

Insect growth depends on temperature and nutrient. Intake nutrients activate insulin signaling pathway, which mediatesthe nutrient signal to coordinate growth in entire body. A subtropical species, Maruca vitrata (Lepidoptera: Crambidae),gives serious damages on various Fabaceae crops. This study predicted seven components (InR, IRS, PI3K, PTEN, Akt,mTOR, FOXO) of the insulin signal and showed that some of the insulin gene expression levels are highly correlatedwith developmental rates. These correlations may be applied to amend a temperature-dependent growth modeling of M.vitrata.
