Resumen
La producción bananera argentina está destinada exclusivamente al consumo
interno y muestra deficiencias de manejo en las etapas de producción y poscosecha. Los
frutos del banano son muy sensibles cuando se producen lesiones, por lo que los daños
ocasionados por insectos, como los trips (Thysanoptera), favorecen la pérdida de valor
comercial. El objetivo de este trabajo fue estudiar los efectos del embolsado, asociado o
no al deschire, en la incidencia de trips en la floración y fructificación del banano (Musa
acuminata Colla) durante dos ciclos de producción (2010-2011 y 2011-2012), en Laguna
Naineck (Formosa, Argentina). Se utilizó un diseño de bloques completamente aleatorizados
(RCBD) con cuatro tratamientos y cuatro repeticiones. La abundancia de los insectos se
determinó en tres estratos del racimo, y la incidencia, durante la cosecha. La única especie
de trips presente durante el estudio fue Frankliniella brevicaulis Hood. Se detectó un mayor
número de larvas de trips en los estratos inferiores del racimo. El embolsado de los racimos
con deschire redujo la incidencia de F. brevicaulis en un 54% y 66% cada ciclo de estudio
respectivamente y favoreció el aumento en la longitud de los dedos con respecto al control,
en 9% y 10% para el primer y segundo año de estudio, respectivamente.
Argentina’s banana production is exclusively destined for domestic consumption and can be used to illustrate management deficiencies in production and post-harvest stages. Banana fruits are very sensitive to injuries and thrips (Thysanoptera) damage results in loss of commercial value. The aim of this work was to study the effects of bagging and its association with “deschire” (manual removal of male floral structures) in relation to the incidence of thrips on the flowering and fruiting of banana (Musa acuminata Colla). The study was carried out during 2010-2011 and 2011-2012 in Laguna Naineck (Formosa, Argentina). Randomized Complete Block Design (RCBD) with four treatments and four replicates was used during two production cycles. The abundance of the insects was determined in three strata of banana bunches and the incidence was estimated at harvest. The only species of thrips present during the study was Frankliniella brevicaulis Hood. A higher number young thrips were detected in the lower strata of bunches. Bagging of the banana bunches with deschire reduced the incidence of F. brevicaulis by 54% and 66% each year of study respectively and favored an increase in the length of the fingers compared to a control crop, in 9% and 10%for the first and second year of study respectively.
