Resumen
El presente trabajo experimental se desarrolló en la finca "Hermanos Calle", en el cantón El Triunfo, Provincia del Guayas, el objetivo general fue Evaluar dos moléculas química y orgánica para el control de insectos plaga que afectan a la calidad del racimo de banano. Para determinar el efecto que se obtiene con nuevas moléculas a base de sustancias orgánicas que se puedan mezclar con el polietileno de baja densidad en la aplicación para el control se insectos plagas que afectan a la calidad del racimo de banano. Se realizó la presente investigación en la semana 52 del 2019, enfundando 50 racimos del tratamiento Biflex + Corbatín Químico (Durflex) y enfundo 50 racimos del tratamiento Biflex + Corbatín Orgánico (Controlflex), identificado
con cinta de color café.En la semana 5 del 2020, se evaluó 25 racimos por cada tratamiento experimental en el campo con edad del racimo de 5 semanas de gestación en la planta; se observó y cuantificó el total de dedos afectados por presencia de daños causados por los insectos plaga. En la semana 10 del 2020, se evaluó 25 racimos por cada tratamiento experimental en la planta empacadora, obteniendo como resultados inicialmente que el tratamiento convencional Biflex + Durflex; mantiene un mejor control al momento de realizar el comparativo con el tratamiento Biflex + Controlflex, ante la presencia de daños causado por insectos, afectando a la calidad del racimo de banano. Los resultados en cuanto las variables (Número de manos, número de dedos, thrips de la flor, thrips de la mancha roja, pyroderces, cohinilla, peso de racimo,
calibre de dedo, longitud de dedo, merma en dedos, merma en libras), para lo cual las urucas variables que no tuvieron igualdad significativa estadísticamente fueron pyroderces, cochinilla, merma en dedos y merma en
libras.
The present experimental work was carried out in the "Hermanos Calle" farm, in El Triunfo canton, Guayas Province, the general objective was to evaluate two chemical and organic molecules for the control of plague insects that affect the quality of the banana bunch. To determine the effect that is obtained with new molecules based on organic substances that can be mixed with low density polyethylene in the application for the control, insects pests that affect the quality of the banana cluster. The present investigation was carried out in week 52 of 2019, covering 50 clusters of the Biflex + Chemical Bowtie (Durflex) treatment and wrapping 50 clusters of the Biflex + Organic Bowtie (Controlflex) treatment, identified with brown tape. In week 5 of 2020,25 clusters were evaluated for each experimental treatment in the field with cluster age of 5 weeks gestation in the plant; The total number of fingers affected by the presence of damage caused by pest insects was observed and quantified. The results regarding the variables (Number of hands, number of fingers, thrips ofthe flower, thrips ofthe red spot, pyroderces, cochinilla, clusterweight, finger caliber, finger length, finger loss, loss in pounds) , for which the only variables that did not have statistically significant equality were pyroderces, cochineal, loss in fingers and loss in pounds.
