The goal of this research was to study the occurrence and also evaluate the frequency of stored-product insects in industrialized dog food commercialized from the Metropolitan Region of the city of Recife (MRR). Samples of dog food was collected from pet food establishments located in the MRR, and submitted to the extraction of insects in Berlese-Thulgren apparatus during 24-hour and 30 days pos collection, at the Laboratory of Parasitic Disease of Domestic Animals of the Veterinary Department of Medicine at Rural Federal University of Pernambuco State Brazil. The insects captured were preserved in 70% ethanol solution at polyetilen recipients. The results showed the presence of four different genus of stored-product insects in industrialized dog food from MRR as following Tribolium (55.21%), Oryzaephilus (31.25%), Rhyzopertha (8.85%) and Lasioderma (4.68%). In the city of Recife, Lasioderma serricorne (62.32%) was the most frequent specie following Oryzaephilus surinamensis (26.17%), Tribolium castaneum (11.38%) and Rhyzopertha dominica (0.13%). The samples from open products (in bulk) were more infested than those obtained from closed one. The same pattern was observed from insects obtained during 24 hour and 30 days pos collection by Berlese-Thulgren apparatus. The results indicate that some factors as the exposition of the dog food to the environment, rotation of the products in the Pet food store, management of dog food storage and the packing must be monitored to prevent the insects’ infestations and their damages.
