IMPACT OF Thrips palmi ON THE DEVELOPMENT AND PRODUCTION OF NARANJILLA (Solanum quitoense Lam.) IN PASTAZA AGROPRODUCTIVE SYSTEMS, ECUADOR

Abstract

The research was carried out in the cultivation of naranjilla (Solanum quitoense Lam.), an item highly appreciated by several producers in the province of Pastaza, the problem arises from the high amount of the agrochemical complex to control pests and increase the size of the fruit. Also, the poor ability to identify T. palmi confuses damage and symptoms with the phytotoxicity of the plant caused by the use of pesticides. It was found that the quantitative variable, plant height, presented highly significant differences between the mean values of the farms or replicas at all evaluated times (days 1, 8, 16 and 24). However, no significant differences were observed in the other variables. It was evident that 100% of the plants on the two farms were infested by T. palmi, located on the upper part of the young leaves causing a chlorotic and rice-like yellowing when feeding. This made it difficult for the producer to make a correct diagnosis. It is concluded that it is essential to carry out research that contributes to the control of this pest.

Resumen

La investigación se realizo en cultivo de naranjilla (Solanum quitoense Lam.) un rubro muy apreciado por varios los productores en la provincia de Pastaza, el problema surge por la alta cantidad del complejo de agroquímicos para controlar las plagas y aumentar el tamaño del fruto. también, la poca capacidad para identificar a T. palmi confunden daños y síntomas con la fito-toxicidad de la planta causada por el uso de pesticidas, Se encontró que la variable cuantitativa, altura de la planta, presentó diferencias altamente significativas entre los valores medios de las fincas o réplicas en todos los momentos evaluados (días 1, 8, 16 y 24). Sin embargo, no se observaron diferencias significativas en las demás variables. Se evidenció que el 100% de las plantas de las dos fincas estaban infestadas por T. palmi, localizas en el haz de las hojas jóvenes provocando un amarillamiento clorótico y arrocetado al alimentarse. Esto dificultaba el diagnóstico correcto por el productor. Se concluye que es indispensable realizar investigaciones que contribuyan al control de esta plaga.
