Uso de sensores remotos para identificar insectos -plaga asociados a Hylocereus megalanthus para su control mediante técnicas de precisión en el cantón Palora

Abstract

The objective is to use remote sensing to identify insect-pests associated with Hylocereus megalanthus for their control using precision techniques. The methodology was based on a documentary design and information gathering, carrying out field trips in Los Lirios, Numbaime, Los Laureles and Sangay in Palora canton, Morona Santiago province, in order to identify areas affected by agents that cause symptomatology in crops. Aerial images obtained from a drone were processed using Agisoft Metashape Professional software to subsequently calculate the Normalized Difference Vegetation Index (NDVI), which identified and mapped affected areas in the crops. The results made it possible to identify the diversity of insects associated with the pitahaya crop, and a multispectral camera was used to determine the state of health of the crops through color variations in the areas affected by harmful organisms. To sum up, precision agriculture is fundamental for pest control in pitahaya amarilla. However, the implementation of remote sensing and precision techniques allows the characterization of crops, soil and climatic factors to apply the appropriate treatment, avoiding the excessive use of agrochemicals.
