Hyperspectral remote sensing was used to detect stress on potted rice plants caused by the Brown Planthopper (BPH), Nilaparvata
lugens (Sta

l). BPH damage influenced reflectance of rice plants compared to uninfested plants in the visible and
near-infrared regions of the electromagnetic spectrum. Correlations between plant reflectance and BPH damage, when plotted
against wavelengths, enabled us to identify four sensitive wavelengths, at 1986, 665, 1792 and 500 nm, in relation to
BPH stress on rice plants. Based on rice plant reflectance corresponding to the sensitive wavelengths, three hyperspectral
indices were developed. The BPH damage showed a positive association with normalized pigment chlorophyll index, and
a negative relationship with normalized difference vegetation index and soil adjusted vegetation index. Using rice plant
reflectance corresponding to the sensitive wavelengths, a multiple-linear regression model was developed and validated,
which would facilitate assessment of BPH damage based on rice plant reflectance, thereby ensuring prompt forewarning to
stakeholders.
