GOMEZ, Rodrigo S.. Attractivity of different Baits on Trogids (Coleoptera) in the Autochthonous Forest "El Espinal", Río Cuarto (Córdoba, Argentina). Rev. Soc. Entomol. Argent. [online]. 2005, vol.64, n.1-2, pp.103-105. ISSN 0373-5680.

A study to determine the food attractivity of baits on the species of Trogidae present in the Autochthonous Forest El Espinal in Río Cuarto City (Córdoba, Argentina) was performed. Pitfall traps baited with beef (3), pork (3), chicken giblets (3), human excrement (3), dog excrement (3) and witness traps (without bait) (3) were used, making up a total of 18 traps. Four species of Trogidae were collected Omorgus suberosus (Fabricius), Polynoncus aeger (Guérin-Meneville), Polynoncus gemmingeri (Harold) and Polynoncus pilularius (Germar), which showed a preference for decomposing meat, especially chicken and pork, followed by dog excrement. Thus suggesting a necrophagous-coprophagous behavior with a tendency to the necrophagy. In an additional sampling light traps were used; Omorgus ciliatus (Blanchard) was collected in these.
