| dc.description | Banana (Musa paradisiaca) is the main agricultural export product in Ecuador, generating a great socio-economic impact in the country. However, this crop is constantly attacked by pests and diseases throughout its production cycles, which is why the use of natural enemies as biological controllers is emphasized. S. fusca is an insect that belongs to the Lepidoptera order of the Limacodidae family, its larvae feed in a gregarious way, initially the damage is caused on de margins of the leaves, they leave perforations on the edges, destroying a large part of the leaf area, causing the decrease of the productive system. From the first instar they feed in the place where their eggs are laid, they remain grouped and consume up to half the thickness of the leaf blade, then they consume the entire leaf, leaving only the vein. Through the technique of using natural enemies, it is possible to keep the damage levels of S. fusca below the economic threshold. Preventing economic losses since a larva can devour 40 cm of leaf, which means 45 or 50 larvae can completely devour a leaf. Among the natural enemies of this pest are mainly the parasitoids of the Braconidae, Ichneumonidae, Tachinidae, Chalcididae, Eulophidae families and predators of the Pentatomidae family, among others, being the parasitoids the biological controllers that exert greater control over this pest. | es_ES |

| dc.description.abstract | El banano (Musa paradisiaca) es el principal producto agrícola de exportación en el Ecuador, generando un gran impacto socio-económico en el país. No obstante, este cultivo es atacado constantemente por plagas y enfermedades a lo largo de su ciclo productivo, razón por la cual se enfatiza en el uso de los enemigos naturales como controladores biológicos. S. fusca es un insecto que pertenece al orden lepidoptera de la familia Limacodidae, la alimentación de sus larvas es de forma gregaria, inicialmente el daño lo ocasionan en los márgenes de las hojas, dejan perforaciones en los bordes, destruyendo gran parte del área foliar, ocasionando la disminución del sistema productivo. Desde el primer instar se alimentan en el lugar donde se realizan las posturas de sus huevos, se mantienen agrupadas y llegan a consumir hasta la mitad del grosor del limbo de la hoja, seguidamente consumen toda la hoja dejando solo la nervadura. Mediante la técnica del uso de los enemigos naturales se puede lograr mantener los niveles de daño de S. fusca por debajo del umbral económico. Previniendo perdidas económicas ya que una larva puede llegar a devorar 40 cm de hoja, lo que significa que 45 o 50 larvas pueden devorar completamente una hoja. Entre los enemigos naturales de esta plaga se encuentran principalmente los parasitoides de las familias Braconidae, Ichneumonidae, Tachinidae, Chalcididae, Eulophidae y depredadores de la familia Pentatomidae, entre otras, siendo los parasitoides los controladores biológicos que mayor control ejercen sobre esta plaga. | es_ES |
