ABSTRACT

Due to limited knowledge of Siphonaptera fauna of the Cavia aperea (Brazilian guinea pig) in the State of Rio Grande do Sul, 43 specimens were examined. Six percent of the Brazilian guinea pigs were parasitized with Siphonaptera, which were identified as Polygenis (Neopolygenis) atopus and Polygenis (Polygenis) axius proximus (Rhopalopsyllidae), both with 2.3% of prevalence. P. (Neopolygenis) atopus and P. (Polygenis) axius proximus are reported for the first time on C. aperea in the State of Rio Grande do Sul, Southern Brazil.

ABSTRACT

I was studied the histology of Amblyomma tigrinum (Ixodidae) an ixodid fick. Three A. tigrinum engorged females were dissected, collected ovary and tracheae, and fixed in Bouin's aqueous fixative during 24 hours; the organs were cut at a thickness of 6-7 um and stained by hematoxylin-eosin. Ovary of A. tigrinum (Fig. 1) showed two cellular layers, similar to the ovary of D. andersoni and B. microplus, being one outer (oocyts) and the inner layer (epithelial cells). Trachea (Fig. 2) showed a cellular layer and a chitions spiral, similar to D. andersoni
