| dc.description | This document seeks to be a contribution to sugarcane producers to eradicate the stem borer D. saccharalis, which is a pest that causes economic damage to sugarcane crops. This pest produces direct and indirect damage by attacking the crop in the larval state, in the first instars the larvae attack the leaf blade feeding on the parenchyma, in the second instar it feeds on the central nerve of the leaf and in the third and fourth instar penetrates the stem causing the death of the growing point. It is a potentially important pest due to the damage it causes to the crop and to industrial performance, these harms, in large part or in its entirety, the agricultural producers who are dedicated to the elaboration of this item, since they do it as an economic sustenance for the families. through its national and international marketing. Sugar farmers maintain breeding and release programs for egg parasitoids and larval parasitoids to control this insect, which is reported in Ecuador and is distributed in all producing areas of the country. The best and most recommended management is biological control, through the use of the most efficient natural enemies, such as parasitoids and predators, which effectively eradicate the eggs and larvae of D. saccharalis, which allows for increased production and better results. industrial returns. | es_ES |

| dc.description.abstract | Este documento busca ser un aporte para los productores de caña de azúcar para erradicar el insecto barrenador del tallo D. saccharalis que es una plaga que causa daños económicos al cultivo de la caña de azúcar. Esta plaga produce daños directos e indirectos atacando al cultivo en el estado larvario, en los primeros instares las larvas atacan la lámina de las hojas alimentándose del parénquima, en el segundo instar se alimenta de la nervadura central de la hoja y en el tercer y cuarto instar penetra en el tallo causando la muerte del punto de crecimiento. Es una plaga potencialmente importante por los daños que causa al cultivo y al rendimiento industrial, esto perjudica en gran parte o en su totalidad a los productores agrícolas que se dedican a la elaboración de este rubro, ya que lo realizan como sustento económico para las familias por medio de su comercialización nacional e internacional. Los agricultores azucareros mantienen programas de cría y liberación de parasitoides de huevos y parasitoides larvarios para el control de este insecto, el cual está reportado en Ecuador y se distribuye en todas las zonas productoras del país. El mejor y más recomendado manejo es el control biológico, mediante el uso de los enemigos naturales más eficientes, como los parasitoides y los depredadores, que erradican eficazmente los huevos y las larvas de D. saccharalis, lo que permite aumentar la producción y mejorar los rendimientos industriales. | es_ES |
