Detection of infestation by Callosobruchus maculatus in mung bean using near-infrared hyperspectral imaging

► NIR hyperspectral imaging can be a non-destructive tool for detection of insect infestations. ► Detection of pupal and adult stages was better than egg or larval stages. ► Top three significant wavelengths were identified using principal component analysis. ► This data can be used to develop low cost multispectral systems for insect detection.
