Parasitic arthropods of some wild rodents from Jureia-Itatins Ecological Station, State of Sao Paulo, Brazil

A study of the associations between three species of rodents in the Atlantic forest and their parasitic arthropods was undertaken at the Jureia-Itatins Ecological Station, located in the State of Sao Paulo, Southeastern Brazil, from March 1989 to February 1990. Individuals of three species, Oryzomys...

Portuguese abstract:A study of the associations between three species of rodents in the Atlantic forest and their parasitic arthropods was undertaken at the Jureia-Itatins Ecological Station, located in the State of Sao Paulo, Southeastern Brazil, from March 1989 to February 1990. Individuals of three species, Oryzomys russatus, Proechimys iheringi and Nectomys squamipes were captured and examined for ectoparasites. Eleven species of parasitic arthropods were found, including four species of insects and seven of Acari. Parasitism intensity, phenology, and rainfall were positively correlated with the abundance of the ectoparasites and their hosts. The most abundant host was O. russatus (Muridae: Sigmodontinae), and the most common parasite on it was the laelapid mite Gigantolaelaps oudemansi. The cuterebrid Metacuterebra apicalis caused myiasis in O. russatus. A mutualistic association between the staphylinid beetle Amblyopinus sp. and its host P. iherini (Echimyidae) was observed. The few N. squamipes captured had small numbers of ectoparasites.
