| dc.description | Rice is one of the main products of the basic food basket in homes, as well as one of the main sources of employment for many Ecuadorians. Diatraea saccharalis is a pest that affects rice cultivation, notably reducing its yield, because its damage causes the loss of tillers. These insects attack in their larval stage, penetrating the stems of the plants, making galleries inside, causing it to reduce the growth of the floral primordium. When the larvae just emerge, they feed on the leaves and later enter the stem, feeding on it, causing a dead heart. The cultural measures that must be carried out are: the elimination of residues from past crops, weeds that serve as a source of host for the insect. This insect is one of the most common in rice cultivation, they are not found in large populations, but the small quantities that are found can affect a large part, since its incidence causes low yields in production. | es_ES |

| dc.description.abstract | El arroz es uno de los principales productos de la canasta básica en los hogares, además una de las principales fuentes de empleo para muchos ecuatorianos. Diatraea saccharalis es una plaga que afecta al cultivo de arroz, reduciendo notablemente su rendimiento, debido a que su daño ocasiona la perdida de los macollos. Estos insectos atacan en su estado de larva, penetrando los tallos de las plantas realizando galerías en el interior, provocando que reduzca el crecimiento del primordio floral. Cuando las larvas recién emergen se alimentan de las hojas y posteriormente ingresan al tallo, alimentándose del mismo provocando corazón muerto. Las medidas culturales que se deben de realizar son: la eliminación de residuos de las cosechas pasadas, malezas que servir como fuente de hospedero para el insecto. Este insecto es uno de los más comunes en el cultivo de arroz, no se encuentran en grandes poblaciones, pero las pequeñas cantidades que se encuentren pueden afectar en gran parte, ya que su incidencia ocasiona bajos rendimientos en la producción. | es_ES |
