| dc.description | The cultivation of rice O. sativa L is the most important cereal for human nutrition. Countries like China and India produce about 55% of the world's rice production. The environmental conditions of Ecuador promote its development since it is the basic food in the diet in our country. The same one that is sometimes harvested three times a year. However, it is attacked by insect pests that reduce its productivity. One of those insects, Tibraca limbativentris, causes damage that in high incidence affects productivity by more than 90%. This degree work aims to detail the damage caused and indicate the control methods of the brown stink bug T. limbativentris in rice cultivation. The feeding habit of adults and nymphs by sucking the sap from the rice stem by the brown stink bug T. limbativentris leads to almost total losses of the estimated production. The main biological control is carried out by the new parasitoid Telenomus podisi, also registering attacks by parasitoids of the genera Trissolcus, Oencyrtus and a eulophidium at levels below 10%. Varietal control is also an alternative control followed by chemical control with biological and chemical insecticides is the best form of control against the brown stink bug T. limbativentris in rice crops. Constantly evaluating brown stink bug T. limbativentris in the vegetative and reproductive phase is important to reduce rice crop losses. . | es_ES |

| dc.description.abstract | El cultivo del arroz O. sativa L es el cereal de mayor importancia para la alimentación humana. Países como China e India producen cerca del 55% de la producción mundial de arroz. Las condiciones ambientales del Ecuador promueven su desarrollo ya que es el alimento básico en la dieta en nuestro país. El mismo que en ocasiones a cosechar tres veces por año. Sim embargo, es atacado por insectos plagas que reducen su productividad. Uno de esos insectos el Tibraca limbativentris el mismo que ocaciona daños que en altas incidencia afecta la productividad en mas del 90%. Este trabajo de titulación tiene como objetivo el detallar los daños ocasionados y señalar los métodos de control del chinche marrón T. limbativentris en el cultivo del arroz. El hábito de alimentación de adultos y ninfas al succionar la sabia del tallo de arroz por parte del chinche marrón T. limbativentris conlleva a perdidas casi totales de la producción estimada. El principal control biológico es realizado por el parasitoide de nuevos Telenomus podisi, también, registra ataques por parasitoides de los géneros Trissolcus, Oencyrtus y un eulophidio en niveles inferiores del 10%. El control varietal también es una alternativa de control seguido del control químico con insecticidas biológicos y químicos es la mejor forma de control contra el chinche marrón T. limbativentris en los cultivos de arroz. Evaluar constantemente chinche marrón T. limbativentris en fase vegetativa y reproductiva es importante para reducir las pérdidas del cultivo del arroz. | es_ES |
