Evaluación de dos saberes ancestrales y sus prácticas agroecológicas en el manejo de insectos plagas del cultivo de pimiento (Capsicum annuum), en sectores rurales del cantón Babahoyo

The cause of production loss in the bell pepper crop in Ecuador is mainly due to the incidence of sucking pests, defoliators and fruit borers; which, to combat them, agrochemicals are used that cause severe problems to the ecosystem and human health. These insecticides, in addition to controlling pests, are polluting agents of the environment and in turn, kill insect species that are natural predators of pests of the bell pepper crop; therefore, the use of these chemicals is ending with species that have been beneficial in the cultivation of bell pepper; apparently due to ignorance or low interest shown to ancestral knowledge, forgetting that agricultural production in its beginnings was managed with knowledge and use of natural products. It is a priority need to promote the application of the ancestral wisdom of the native peoples, to contribute to the improvement of bell pepper production and environmental care. The experiment was carried out on the grounds of the "Jorge Yánez Castro" Farm, belonging to the Faculty of Agricultural Sciences, Technical University of Babahoyo; located at Km 7 of the Babahoyo - Montalvo road, between the geographical coordinates 79º 32' 00'' West longitude and 01º 47' 49'' South latitude; with an altitude of 8 meters above sea level. The experimental design used was divided plots with 3 treatments (allelopathic-repellent barriers), 3 sub-treatments (botanical biopreparations) and 3 replications, with the respective analysis of variance and comparison of the averages with the LSD FISHER test at 5% significance; the formulas used were neem extract, chili and oregano biofermented (individual). Based on the results obtained in the present research it can be indicated that, through the application of ancestral knowledge and its agroecological practices in the cultivation of bell pepper, an efficacy was achieved in the control of insect pests such as: Aphids, whitefly and thrips, with the application of botanical biopreparations (biofermented Neem, Biofermented Chili, Biofermented Oreganon), which allowed reducing the population incidence of insect pests in the bell pepper crop, due to the repellent, insecticidal and beneficial insect attractant action that each of these biocides possess, being widely used for the control of leafminers, suckers, borers and chewing insects.
