Identificación y control de plagas y enfermedades en Polylepis Racemosa en la zona de Toacazo, Tanicuchi y Pastocalle.

Abstract

The present investigation was carried out in the T.T.P. located in the north of the province of Cotopaxi, in order to identify pests and diseases in Polylepis racemosa and propose the appropriate control to combat them. For the development of the present experimental work, a diagnosis was made of the current phytosanitary situation of the forest species under study. To establish the incidence of pests and diseases, we proceeded to perform the respective sampling of them, in two plots in different altitudinal floors, located at 3 460 and 3 770 meters above sea level. For sampling, the simple random sampling method was used. According to data obtained in the field, 4 species of pests were found in different stages and 1 disease. A specimen that acts as a biological controller was identified. In order to deepen the investigation, data were taken in the field such as: DAP, Total Height of the Stem and Size of the Cup. With the field data, the Basal Area and the Volume of the 30 individuals sampled were calculated. From each variable a descriptive statistical analysis was carried out. To collect information, a survey was conducted to the community of the study area. As a result of the investigation, each species of pest was identified with the help of taxonomic keys: Agelastica alni, Mocis latipes, Sirex noctilio, Cardioscarta sp. and the disease: Peronospora sp., for which control measures are proposed, being the most beneficial the biological control, in the short and long term. In this way Polylepis racemosa can be conserved without compromising the environment.
