ResumoNIMPHS OF RHlPlCEI'IIALUS SAN(;UINEUS (LATREILLE) (IXODOIDEA, Ixo-DIDAE) lN DIFFERENT NUTRITIONAL STAGES.With lhe purpose of characterize morphologically lhe hemocytes of larvae and nymphs 01' Rhipicephalus sanguineus on ditTerent nutritional phases, it was obtained sal1lples ofhaemolYl1lph were obtained by sectioning the forel egs and collecting lhe drop there formed.A fter dried, the samples were fixed by methanol and stained by Giel1lsa.Microscopical observation resulled in lhe characlerization of five basic cellular lypes: prohemocyles, plasmatocytes, granulocytes, spherulocytes and oenocytoids.Moreover, undefined cell types, whose morphological patterns didn 't have correlation with the characleristics cited for hemocytes, were found in low frequency.The change in the relative cOl1lposition of the haemo-I imph was characterized by decrease of the number of granulocytes and greater variabilily of the cell types present in the hel1lolyl1lph as the tick evolved.This fact l11ay be linked to the alterations that lhese ce lls sutTer aI ong the development of the tick.
