Wild rodents in captivity can be attacked by ectoparasites which affect their health. This study aimed to identify the natural ectofauna of the guinea pig Galea spixii Wagler, 1831 in captivity in the semiarid region of Rio Grande do Norte and to study the behavioral dynamics of the most prevalent ectoparasitism. Specimens (n=40) of G. spixii in captivity in the Center for Wild Animal Multiplication (Centro de Multiplicação de Animais Silvestres da Universidade Federal Rural do Semi-Árido) were anesthetized from March to October 2010 and examined searching for ectoparasites. The guinea pigs presented Amblyomma sp. (Koch, 1844), Demodex sp. (Owen, 1843) and Gliricola quadrisetosa (Ewing, 1924). The frequency of data of G. quadrisetosa, the most prevalent species in the study, showed that the mean of lice collected in the different body parts was higher in females (p=0,0498). The climatic period did not influence the frequency of G. quadrisetosa collected from the animals (p>0.05). Demodex sp. was the first record of ectofauna identified in G. spixii in semiarid conditions in Brazil. The data indicate that the body surface area and the climatic period did not influence the infra-population of Gliricola quadrisetosa found in Galea spixii. |
