The aim of the paper is to evaluate the economic impact of the invasive species Zea mays ssp. mexicana (teosinte) on the corn fields in Aragón. The main objective is to estimate the private and social costs associated with the species and to perform an economic evaluation of some control alternatives following the technical advices for control and eradication established by the regional government institutions. The analysis quantifies the losses generated by the presence of teosinte in relation to different infestation degrees and incorporates a classification of control measures with respect to their economic profitability. The results confirm that the control measures proposed by technical experts are adequate from the economic perspective and contribute with the evaluation of social costs of measures.
