Hard yellow maize is the most important grain worldwide, as it is a key source of food for chickens and pigs, providing essential protein for humanity. This study evaluates the benefits of releasing seeds of genetically modified hard yellow corn (MADBt), resistant to codling moth (Spodoptera frugiperda), in Los Ríos, Ecuador. To analyze the economic benefits to producers, partial budget models that provide the change in producer margin and the marginal cost benefit were used.

In addition, risks associated with agricultural production were incorporated through Monte Carlo simulations using @Risk software. Information on costs, production and prices was obtained through a survey of producers in Los Ríos. It is concluded that (i) producers benefit from a Marginal Cost Benefit ratio of 1,09 and an increase in ...
