Abstract
La papa es uno de los principales cultivos alimenticios de gran importancia socio-económica para el Perú. El cultivo de la papa, al igual que otros cultivos no escapa a los problemas entomológicos que originan efectos negativos en su producción. El "Gorgojo de los Andes" Premnotrypes vorax. Hustache, es una plaga de importancia que ataca al cultivo de la papa, los daños que ocasionan a los tubérculos son graves llegando en algunos casos al 100 por ciento. Los objetivos de la presente tesis son: Evaluar el nivel de conocimiento de los agricultores sobre los diferentes componentes del manejo integrado del gorgojo de los Andes implementados anteriormente en esta comunidad. Determinar los niveles de aceptación del manejo integrado del gorgojo de los Andes. Examinar las percepciones o modificaciones respecto de estas prácticas. Se emplearon métodos, de observación directa en campo. Aplicación de encuestas (informal y formal). Análisis de la data y su procesamiento a través del software SPSS. Los resultados indican que, el nivel de conocimiento en relación a las tres estrategias consideradas es, reducción de poblaciones en campo 65 por ciento, intercepción de migraciones 63 por ciento y, reducción de poblaciones en almacén 53 por ciento, predominando un conocimiento regular y, este conocimiento es indiferente del grado educativo del agricultor. De 10 componentes generales considerados para nuestro estudio, los agricultores sin instrucción, muestran que en tres de ellos registran mayor conocimiento, empleo de pollos con 57 por ciento, zanjas 50 por ciento, recojo manual 79 por ciento. En los otros siete componentes se registra un desconocimiento superior al 50 por ciento. En los agricultores con primaria completa, de 10 componentes generales considerados, en ocho hay un conocimiento superior al 50 por ciento, dos componentes registran un desconocimiento superior al 50 por ciento, empleo de productos químicos (57 por ciento), y siembra y cosecha oportuna (86 por ciento). En conclusión, se determinó que, el mayor nivel de conocimiento de los agricultores sobre las estrategias de control fue la reducción de la población de gorgojos en campo con 65 por ciento. Se halló que, los que identifican más estados del gorgojo corresponde a los agricultores con primaria completa, siendo el adulto con 14 por ciento y la larva también con un 14 por ciento. Se halló que, el conocimiento sobre el control de los estados del gorgojo, es mayor en los agricultores con primaria completa, siendo el estado adulto como el más conocido para llevar a cabo el control con 71 por ciento. Se halló que, en los agricultores sin instrucción, de doce prácticas específicas para manejo integrado del gorgojo de los Andes, tres de ellas son usadas, empleo de pollos como predatores con 64 por ciento, remociones de campos 50 por ciento, y recojo manual de adultos con 64 por ciento. Se halló que, en los agricultores con primaria completa, de doce practicas específicas MIGA, siete son usadas sobre el 50 por ciento. En cambio, en los agricultores sin instrucción solo usan tres de ellas. Se encontró que, al ser una comunidad con agricultura de subsistencia, dan más importancia a aquellas prácticas que están basadas en la tradición, como las prácticas referidas a, el empleo de pollos como predatores, remociones de los campos, empleo de mantas, extracción de plantas huachas, zanjas en campo.
The potato is one of the main food crops of great socio-economic importance for Peru. Potato cultivation, like other crops, does not escape entomological problems that cause negative effects on its production. The "Andean Weevil" Premnotrypes vorax Hustache., is an important pest that attacks the potato crop, the damage caused to the tubers is serious, reaching 100 percent in some cases. We propose: Evaluate the level of knowledge of farmers on the different components of the integrated management of the Andean weevil previously implemented in this community. Determine the levels of acceptance of the integrated management of the Andean weevil. And examine perceptions or modifications regarding these practices. Methods of direct observation in the field were used. Application of surveys (informal and formal). Data analysis and processing through SPSS software. The results indicate that the level of knowledge in relation to the three strategies considered are: reduction of populations in the field 65 percent, interception of migrations 63 percent and reduction of populations in storage 53 percent, prevailing a regular knowledge and, this knowledge is regardless of the educational level of the farmer. Of 10 general components considered for our study, farmers without instruction show that in three of them they register greater knowledge about the use of chickens with 57 percent, ditches 50 percent, manual collection 79 percent. In the other seven components there is a lack of knowledge greater than 50 percent. In farmers with completed primary education, of the 10 general components considered, eight have knowledge of more than 50 percent, two components register ignorance of more than 50 percent, use of chemical products (57 percent), and timely planting and harvesting (86 percent). In conclusion, it was determined that the highest level of knowledge of the farmer about control strategies was the reduction of the weevil population in the field with 65 percent. It was found that those who identify more states of the weevil correspond to farmers with primary complete, being the adult with 14 percent and the larva also with 14 percent. It was found that the control knowledge of the weevil states is higher in farmers with complete primary, being the adult state, the best known for its control with 71 percent. It was found that, in farmers without instruction, of twelve specific practices for MIGA, three of them are used, use of chickens as predators with 64 percent, field removals 50 percent, and manual collection of adults with 64 percent. It was found that, in farmers with completed primary school, of twelve specific MIGA practices, seven are used over 50 percent. On the other hand, farmers without education only use three of them. It was found that, being a community with subsistence agriculture, they give more importance to those practices that are based on tradition, such as the practices referred to, the use of chickens as predators, removal of the fields, use of blankets, extraction of volunteer plants, trenches in the field.
