Manejo del insecto plaga Rupela albinella Cramer, 1960 en el cultivo del arroz (Oryza sativa L.) en el Ecuador

This document details the management of the pest insect Rupela albinella in rice cultivation (Oryza sativa L.) in Ecuador. The general objective was to describe the management of the pest insect Rupela albinella in rice cultivation. To prepare the document, information was collected from magazines, virtual libraries and scientific articles. The information obtained was interpreted, summarized and analyzed to produce relevant information. The conclusions determined that R. albinella is commonly called Rice Bride. Although it is present throughout the crop's development period, it has not been shown to have economic importance. Large numbers of adults are generally observed perching on rice plants, but their presence has not been linked to yield losses. In Ecuador, rice cultivation is widely distributed along almost the entire coastline. R. albinella is important among the insects that attack this crop due to the damage caused by the larvae. In a severe attack, losses can amount to 50% of the production due to panicle vaneing, rotting and drying of the strongly affected stems; although, regularly the damage they cause does not exceed 5%. The beneficial agents that exert biological control on R. albinella is Telenomus rowanii, a natural enemy of the rice bride that parasitizes the eggs of this insect. As a result of this action, this parasitoid carries out a very important natural biological control of the rice bride.
