Abstract
El presente trabajo de investigación se llevó acabo en los campos de los agricultores de Pueblo Nuevo que sembraron arroz, en las campañas 2015-2016, 2016 – 2017 y 2017-2018. El objetivo fue, determinar el control químico de Tagosodes orizicolus Muir en el cultivo de Oryza sativa L. La muestra se obtuvo del 30 % de una población de 50 agricultores. Las variables evaluadas fueron dosis, frecuencia, mezcla, eficiencia de los productos, costo de insecticidas, costos de producción, rendimiento, entre otras variables. Se concluye que los agricultores de Pueblo Nuevo, en las tres campañas mencionadas utilizaron thiamethoxam (100-120 g.ha-1), clothianidin+ delthamethrin, (250-300ml.ha-1), fenpropathrin (150-200 ml.ha-1), dimetoato, (400-500 ml.ha-1), thiamethoxam + lambdacyhalotrin (300-400 ml. ha-1), imidacloprid (400-500 ml.ha-1), imidacloprid +bifenthrin, (300-400 ml.ha-1); el ingrediente activo thiamethoxan tuvo al menos mejor efectividad de control contra Tagosodes orizicolus Muir. Las dosis de ingrediente activo se incrementaron, por las condiciones climáticas y la humedad relativa, proliferaba con altas temperaturas el insecto llamado Tagosodes orizicolus Muir.

The objective was to determine the chemical control of Tagosodes orizicolus Muir in the cultivation of Oryza sativa L. The sample was obtained from 30% of a population of 50 farmers. The evaluated variables were dose, frequency, mixture, efficiency of the products, cost of insecticides, production costs, yield, among other variables. It is concluded that the farmers of Pueblo Nuevo, in the three mentioned campaigns used thiamethoxam (100-120 g.ha-1), clothianidin + delthamethrin, (250-300ml.ha-1), fenpropathrin (150-200 ml.ha-1) ), dimethoate, (400-500 ml.ha-1), thiamethoxam + lambdacyhalotrin (300-400 ml ha-1), imidacloprid (400-500 ml.ha-1), imidacloprid + bifenthrin, (300-400 ml) .ha-1); the active ingredient thiamethoxan had at least better control effectiveness against Tagosodes orizicolus Muir. The doses of active ingredient were increased, due to climatic conditions and relative humidity the insect called Tagosodes orizicolus Muir, proliferated at high temperatures.
