dc.description | This document refers to the importance of integrated management of Demotispa neivai in oil palm cultivation in Ecuador. The conclusions determine that the cultivation of oil palm constitutes one of the main agro-industrial items, showing, due to its high demand in the market for products and by-products derived from it; the larvae live between the fruits of the green clusters and the base of the arrows; during the day the larvae remain between the spikes of the bunch, feeding on the fleshy part of the spathe, in the area surrounding the bunch peduncle and also scraping the bracts. Integrated management of D. neivai includes different agricultural practices, in addition chemical insecticides can be applied by root route or as stem injection, but these cause environmental damage and in turn eliminate beneficial organisms and currently botanical insecticides are being used to based on citrus extract or biological controls based on bacteria such as Baeuveria sp. and D. neivai is a pest that directly affects production, the adult can consume 1.5 cm2 of the epicarp of the fruit each day. The scraping that it does on the fruits causes losses due to the confusion that it causes producers to recognize the degree of maturity of the bunches at the time of harvest and as a consequence the decrease in oil extraction, its potential can reach up to 24 %, but when the cluster shows 50% damage caused by the insect, this potential can be reduced by 1.04%. | es_ES |

dc.description.abstract | El presente documento hace referencia a la importancia del manejo integrado de Demotispa neivai bondar en el cultivo de palma aceitera en Ecuador. Las conclusiones determinan que el cultivo de la palma aceitera constituye uno de los principales rubros agroindustriales, mostrando por su alta demanda en el mercado de productos y subproductos derivados de ella; las larvas viven entre los frutos de los racimos verdes y la base de las flechas; durante el día las larvas permanecen entre las espigas del racimo, alimentándose de la parte carnosa de la espata, del área que rodea el pedúnculo del racimo y también porque raspan las brácteas. En el manejo integrado de D. neivai se incluyen diferentes prácticas agrícolas como la aplicación de insecticidas químicos que puede ser vía radicular o inyección al estipe, los mismos que pueden causar daños ambientales, muerte de organismos benéficos, en la actualidad se están utilizando insecticidas botánicos a base de extracto de cítricos o controles biológicos a base de bacterias como Beauveria sp. y D. neivai es una plaga que afecta directamente la producción, el adulto puede consumir 1,5 cm2 del epicarpio del fruto cada día. La raspadura que hace en los frutos, causa pérdidas por la confusión que provoca a los productores para reconocer el grado de madurez de los racimos al momento de la cosecha y como consecuencia la disminución en la extracción de aceite, su potencial puede llegar hasta un 24 %, pero cuando el racimo presenta un 50 % de daño provocado por el insecto, dicho potencial puede reducirse en 1,04 %. | es_ES |
