Abstract

MACHADO, Eduardo H.L.; ALVES, Leucio C.; FAUSTINO, Maria A. da G.  and  MACHADO, Erilane de C.L.. Occurrence of weevils (Insecta: Coleoptera) in pet food traded in the Metropolitan Region of Recife, Pernambuco State, Brazil. Neotrop. entomol. [online]. 2008, vol.37, n.5, pp. 602-605. ISSN 1678-8052.  http://dx.doi.org/10.1590/S1519-566X2008000500017.

With the purpose of verifying the occurrence of insect pests in dog food commercialized in the Metropolitan Region of Recife, samples from 15 different pet stores were submitted to the extraction of insects in a Berlese-Tullgren apparatus. Tribolium castaneum (Herbst) (Tenebrionidae) (55.2%) was the most frequent specie followed by Oryzaephilus surinamensis (L.) (Cucujidae) (31.3%), Rhyzopertha dominica (Fabricius) (Bostrichidae) (8.9%) and Lasioderma serricorne (Fabricius) (Anobiidae) (4.7%), all from Coleoptera. Recife showed the highest rate of infestation (53.6%), followed by Olinda (34.4%) and Jaboatão dos Guararapes (12.0%). The infestation by coleopters in the region occurs with high frequency and may represent a threat mainly in commercialized products in bulk.
