Abstract
El presente trabajo de investigación tiene como objetivo determinar la infestación, control e identificación de la cochinilla harinosa en Manihot esculenta Cranst en la localidad de Galindo del distrito de Laredo en la región La Libertad. La investigación comprendió: fase de campo y fase de laboratorio; en campo se visitaron a los agricultores en sus propias plantaciones de yuca, además se colectaron muestras de estados biológicos de las cochinillas harinosa encontradas en las plantas principalmente en la fase fenológica de brotación. La fase de laboratorio con las muestras acondicionadas y correctamente identificadas fue enviada al CENTRO DE DIAGNOSTICO DE SANIDAD VEGETAL de SENASA
(Servicio Nacional de Sanidad Agraria), ubicada en la región de Lima para identificación de la especie de cochinilla harinosa. La población de estudio estuvo conformada por 21 agricultores que siembran frecuentemente el cultivo de yuca; y la muestra estuvo conformada por 19 agricultores. El instrumento utilizado para la recolección de datos fue la aplicación de una encuesta y complementada con la toma de fotografías. Los resultados obtenidos determinaron que la especie de cochinilla que se encontraba infestando las plantas de yuca correspondió a Paracoccus marginatu con una infestación del 15%, el método de control utilizado por todos los agricultores fue el químico, donde el 90% de agricultores usaron el
ingrediente activo Clorpirifos y el 10% correspondió al ingrediente activo Imidacloprid con una dosis de 400 ml/200 litros de agua.
ABSTRACT The objective of this research work is to determine the infestation, control and identification of the mealybug in Manihot esculenta Cranst in the town of Galindo in the district of Laredo in the department of La Libertad. The research included: field phase and laboratory phase; In the field, the farmers were visited in their own cassava plantations, in addition, samples of the biological states of the mealybugs found on the plants, mainly in the phenological phase of sprouting, were collected. The laboratory phase with the conditioned and correctly identified samples were sent to SENASA's Plant Health Diagnostic Center located in the department of Lima for identification of the mealybug species. The study population consisted of 22 farmers who frequently sow cassava; and the sample consisted of 19 farmers. The instrument used for data collection was the application of a survey and complemented by taking photographs. The results obtained determined that the species of cochineal that was infesting the cassava plants corresponded to Paracocus marginatu with an infestation of 15%, the control method used by all farmers was the chemical one, where 90% of farmers used the ingredient active ingredient Chlorpyrifos and 10% corresponded to the active ingredient Imidacloprid with a dose of 400 ml/200 liters of wáter.
