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.
