dc.descriptionRice cultivation is one of the most cultivated and commercialized in the coastal region of Ecuador, however, it is attacked by countless insect pests, whose control is costly and complicated in some cases. The use of microbioles bioinsecticide, currently represents a great alternative to reduce the use of chemical pesticides. The present investigation was carried out in the CEDEGE Babahoyo Project, in this study the alternatives for the control of Rupella albinella with biopesticides in rice cultivars were evaluated. In the field work, the experimental design of "Divided Plots" with two large units and eight treatments was used, divided into three repetitions, two varieties of rice SFL-11 and INIAP FL-01 were used, testing the following control agents: Baculovirus - VPN, Bacillus thuringiensis, Neem and a chemical control with Profenofos, additionally a control without applications was implemented. During the development of the crop, agronomic variables related to production and variables directed to larval mortality were evaluated, in order to establish the Probbit test. The best result was obtained with the Baculovirus treatment at a dose of 0,8 l/ha, which reduced the populations of Rupella albinella in the field by 100%, likewise reduced the percentage of damage compared to the control that maintained the greater damage, being statistically superior to the others. The best economic benefit was obtained with the application of Baculovirus 0,8 l/ha, which kept the crop in better health. The use of profenofos within a pest management program guarantees a decrease in the pest under study, but not in the long term.es_ES

dc.description.abstractEl cultivo de arroz es uno de los más sembrados y comercializados en la región costa del Ecuador, sin embargo, es atacado por un sinnúmero de insectos plagas, cuyo control resulta costosos y complicado en algunos casos. El uso de bioinsecticida microbioles, en la actualidad representa una gran alternativa para la disminución del uso de plaguicidas químicos. La presente investigación se la realizó en el Proyecto CEDEGE Babahoyo, en este estudio se evaluaron las alternativas para el control de Rupella albinella con bioplaguicidas en cultivares de arroz. En el trabajo de campo se empleó el diseño experimental de “Parcelas Divididas” con dos unidades grande y ocho tratamientos, dividido en tres repeticiones se utilizaron dos variedades de arroz SFL-11 e INIAP FL-01 probando los siguientes agentes de control: Baculovirus – VPN, Bacillus thuringiensis, Neem y un testigo químico con Profenofos, adicional se implementó un control sin aplicaciones. Durante el desarrollo del cultivo se evaluaron variables agronómicas relacionadas con la producción y variables direccionadas con la mortalidad de larvas, con el fin de establecer la prueba de Probbit. El mejor resultado lo obtuvimos con el tratamiento de Baculovirus en dosis 0,8 l/ha, el cual disminuyó las poblaciones de Rupella albinella en campo en un 100%, así mismo, redujo el porcentaje de daño en comparación con el testigo que mantuvo el mayor dañó, siendo estadísticamente superior a los demás. El mejor beneficio económico se lo obtuvo en con la aplicación de Baculovirus 0,8 l/ha, el cual mantuvo en mejor sanidad el cultivo. La utilización de Profenofos dentro de un programa de manejo de plagas, garantiza una disminución de la plaga en estudio, pero no en el largo plazo.es_ES
