Abstract
In Ecuador, the cultivation of rice (Oryza sativa L) is affected by various insect pests that cause the deterioration of the vegetation. Therefore, this problem was investigated in the Canton Naranjal in four rice farms covering a total area of 213.8 ha, carrying out "X" sampling with 20 double passes with the entomological net. Geographic Information Systems (GIS) tools were used to geo-reference the insects that prevail in the crop and at the same time observe the locations and know in which phenological stage they are present with the assistance of the BBCH Codification. Thematic maps of pest and beneficial insects were made with Density Kernel allowing the population of insects per m² found in the three samplings to be estimated. The percentages vary by phenological stage, but five pest insects predominate: Hydrellia sp, Tagosodes oryzicolus Müir, Rupella albinella, Oebalus ornatus (Adult), Tibraca limbativentris (Adult - Nymph), the GIS allow a spatial distribution of the pest insects.
