Abstract— Applications of remote sensing in agriculture have increased in recent years, especially for the development of sensors with better spatial and spectral resolutions. The objective of this study was to assess and evaluate the spatial and spectral variability of infection Diatraea saccharalis of sugarcane (Saccharum officinarum) through optical sensors in the Huasteca, Mexico. The methodology consisted in to make in situ measurements with a hyperspectral spectroradiometer in areas with and without apparent damage by the plague. For spatial and scaling representation Landsat 8 images were used. The data obtained in the field showed the spectral behavior of the plague; and the space-spectral reflectance variation was made by visibles and infrared bands for the vegetation. This process is an important approach to take a look from the geographical point of view to the problems related to the risk assessment of plague and diseases, their incidence, spread and severity, as well as support for sampling and monitoring activities. The used of these technologies provides advantages in research and in the implementation of precision farming techniques.
