| English abstract | The feeding behavior and the food preference was studied in P. expansa (Schweigger, 1812) P. unifilis (Troschel, 1848) and P. sextuberculata (Cornalia, 1849). The method used for feeding behavior and food preference was the sampling of all occurrences. The Students' t test was applied on the food items, to compare differences during the development of each species. The main conclusions are: feeding behavior for food, except alive animals, is divided in foraging, approach, olfactory recognition, capture, laceration and ingestion; the persecution behavior was observed for prey activity; cleptoparasitism occurs in the three species and neustophagia mechanism was detected in P. unifilis; P. sextuberculata shows to be almost only carnivorous and P. expansa and P. unifilis show to be omnivorous; P. expansa can be considered more herbivorous in captivity than P. unifilis during the age between one and five years old and more than five years old; P. expansa is more sensitive than P. unifilis concerning the alteration of the food place, mainly the meat, decreasing its consumption, if it is put on a dry place |
