This research was aimed to show that the combination of Integrated Pest Management (IPM) with another complimentary, such as Llovera´s method, was able to control fly population; so, it is used in small and medium-sized farms due to the fact that its implementation requires certain care and it is difficult to implement in larger units. The aim was to add the use of polyphenols of red quebracho in the diet of laying hens as an alternative in the IPM to evaluate the impact on fly population in laying hen farms and to determine if it is economically viable. Two hen-houses with 5000 hens each, owned by a laying hen establishment from Pujato (Santa Fe province) were used. The preliminary positive results in regard to the control of fly larvae allowed to move forward in the control of direct costs for the application of technical and to compare them with the traditional alternatives such as chemical control and cultural practices. Values that are described are expressed in August 2014 current pesos. Two hundred kilos of polyphenols per year were used at a cost of $45/kg = $9000/year, it must be added a complimentary insecticide treatment during summer season consisting of 4 L DDVP at $207 = $828. The treatment total cost equals to $9828 per year. The alternative method with which the comparation was made implies the use of Cyromazine at 500 g/feed ton during 3 months at $ 17 = $765; 4 liters of DDVP at $207/L = $828; 4000 kg of lime at $3/kg = $12000, and labor to remove guano and lime application was of 365 hours at $50 = $18250. The annual total cost of $31843 implies a difference of $22015 between treatments for this farm size. Results obtained by polyphenol application on fly control and cost difference make up a technical and economically viable alternative, contributing in this way to achieve a greater efficiency in IMP, and positively impacting on environmental, social and economic sustainability.
