Objetivo. Por medio del modelo de taller participativo se realizó la caracterización del subsistema de plagas de mora sin espina en el departamento de Risaralda con agricultores de las diferentes asociaciones. Metodología. Se utilizó el análisis multivariado, empleando la técnica de correspondencias múltiples para variables categóricas a fin de hallar los clústers de productores; posteriormente, una prueba Chi-cuadrado comparó los resultados de cada clúster y verificó las diferencias significativas que podían existir dentro de los mismos. Resultados y conclusión. Con base en la presencia de insectos por cada etapa fenológica del cultivo se encontraron cinco clústers de agricultores. Los moricultores del departamento reportaron como organismos presentes en el sistema productivo insectos de las familias Thripidae, Chrysomelidae, Melolonthidae y Aphididae, y de las especies Atta sp., Hepialus sp., Monalonion sp., Prodiplosis sp., Eurhizococcus colombianus, y moluscos como babosas (Orden: Pulmonata); sin embargo, los trips y el barrenador de tallo (Hepialus sp.) fueron los insectos fitófagos más prevalentes. Asimismo, una prueba Chi-cuadrado determinó que, según la percepción del agricultor, los trips son los insectos más prevalentes durante todas las etapas fenológicas del cultivo.
The participatory research with farmers was carried out in order to know the socioeconomic and productive reality of blackberry farmers no thorn (Rubus glaucus Benth) from seven cities in the state of Risaralda, taking into account the technological demands of the crop. It was carried out with 328 producers, grouped into 40 subgroups, participatory methodologies were used such as Participatory Rural Diagnosis, appraisals, direct and participant observation, interviews and semistructured dialogues, group discussions and analysis, information output matrices, ideas for group reflection, talking maps, analysis of qualifications and scores, comparison of opinion groups, workshops, semistructured interviews, field days, participatory research plots and field transects, from an on-demand research scheme. It was found that the cultivation of blackberry no thorn in Risaralda is 90% of peasant agriculture, it is carried out in plots of between 0,5 to 1 hectare, under the modalities of ...
The academic community of the department of Risaralda, in its permanent interest in evidencing the results of the research processes that are carried out from the Higher Education Institutions and as a product of the VI meeting of researchers of the department of Risaralda held in November 2021 presents its work: “The journey of research as a challenge towards new trends”, which reflects the result of the latest research and advances in different lines of knowledge in Agricultural Sciences, Health Sciences, Social Sciences and Technology and Information Sciences, which seek to solve and meet the demands of the different sectors. This work would not have been possible without the help of each of the teachers, researchers and authors who presented their articles that make up each of the chapters of the book, to them our gratitude for their commitment, dedication and commitment, since their sole purpose is to contribute from the academy and science to scientific and technological development in the search for the solution of problems and thus contribute to transform the reality of our society and communities. We also wish to extend our gratitude to the institutions of the Network that made this publication possible: UTP, UCP, UNAD, UNIREMINGTON; UNISARC, CIAF, Universidad Libre, Uniclaretiana, Fundación Universitaria Comfamiliar and UNIMINUTO, institutions that in one way or another allowed this work to become a reality, which we hope will be of interest to you.
