Abstract
El presente trabajo de investigación se realizó durante los meses de Julio a Octubre 2018 en los campos del cultivo de cebolla, agricultores del centro poblado de Talambo, Chepén, La Libertad. El objetivo fue el estudio del control químico de Thrips tabaci Lindeman en Allium cepa L. var. Roja Arequipeña. Los datos se obtuvieron mediante una encuesta realizada a 15 agricultores representativos de la zona evaluándose los insecticidas que utilizan, frecuencia, dosis, mezclas y número de aplicaciones, costos de producción y rendimiento. Se concluye que los agricultores del centro poblado de Talambo, cada campaña utilizan con mayor frecuencia los ingredientes activos como: methomyl, clorpirifos, dimetoato, profenofos, metamidofos, imidacloprid, fentoato, alfacipermetrina, fipronil, acetamiprid, permetrina, además que incrementan el número de aplicaciones de insecticidas, incrementan las dosis de aplicación, aumentan los costos de control del insecto y costos de producción. Finalmente, los agricultores del centro poblado de Talambo, realizaron por aplicaciones excesivas de mezclas de insecticidas para poder controlar a Thrips tabaci Lindeman, debido a que el cambio climático cada año está variando más y eso influye en la incidencia del insecto.
ABSTRACT This research work was carried out during the months of July to October 2018 in the fields of onion cultivation, farmers in the town of Talambo, Chepén, La Libertad. The objective was the study of the chemical control of Thrips tabaci Lindeman in Allium cepa L. var. Red Arequipeña. Data was obtained through a survey of 15 representative farmers in the area, evaluating the insecticides they use, frequency, doses, mixtures and number of applications, production costs and yield. It is concluded that the farmers in the town of Talambo, each campaign use more frequently the active ingredients such as: methomyl, chlorpyrifos, dimethoate, profenofos, methamidophos, imidacloprid, fentoate, alphacypermethrin, fipronil, acetamiprid, permethrin, also increasing the number of applications of insecticides, increase the application doses, increase the costs of insect control and production costs. Finally, the farmers of the town of Talambo, make excessive applications of mixtures of insecticides to control Thrips tabaci Lindeman, because the climate change each year is changing more and that influences the incidence of the insect.
