Ectoparasitos de roedores do município de Tiradentes, Minas Gerais: I. Ectoparasitofauna

Ectoparasites from small mammals from the Cerrado region in the Minas Gerais state, Brazil

“…The observed differences in the number of females and males among mites are noteworthy; the females were more abundant and in some cases no male was seen what is in concordance with other studies (Fonseca 1939, Botelho 1978, Linardi et al 1985, Lopes 1989, Botelho 1990). Numerous factors can explain this phenomenon.…”

“…Among fleas the ratio of females to males was observed similar to other studies (Cerqueira 1975, Linardi 1977, Cerqueira & Linardi 1977, Lopes 1989, Botelho 1990). Following the theory of Linardi & Nagem (1972), slight variation between the number of females and males is a result of the difference of longevity reproductive cycles.…”

Ticks (Acari: Ixodidae) on wild animals from the Porto-Primavera Hydroelectric power station area, Brazil

“…We believe that our results of A. cajennense on a great variety of wild animals (Table) can be linked to the availability of several primary hosts for A. cajennense (horse, cattle, tapir, capybara, peccary). Although a variety of animal species and also humans can be infested by A. cajennense (Aragão 1936, Lopes et al 1998, Pereira et al 2000, present study), the abundance of the infestations will depend on the availability of the primary hosts for the tick. In addition, environmental conditions of the area must have been favorable for the freeliving stages of A. cajennense in the present study.…”

Interrelationship between Ectoparasites and Wild Rodents from Tijucas do Sul, State of Paraná, Brazil

“…In Brazil, the greatest amount of information on ectoparasites of small wild mammals has been obtained from municipalities of the State of Minas Gerais: Viçosa (Whitaker Jr & Mumford 1977), Caratinga (Botelho 1978), Belo Horizonte (Linardi et al 1984, Botelho & Linardi 1996, Juiz de Fora , Tiradentes (Lopes et al 1989) and Serra da Canastra National Park (Whitaker Jr & Dietz 1987), with simultaneous records of mites, fleas and lice. Other Brazilian records of ectoparasites on wild mammals include Ilha Grande, State of Rio de Janeiro (Guitton et al 1986), Ilha de Maracá, State of Roraima (Linardi et al 1991a) and Florianópolis, State of Santa Catarina (Linardi et al 1991b).…”
