| With the purpose of characterize morphologically the hemocytes of larvae and nymphs of Rhipicephalus sanguineus on different nutritional phases, it was obtained samples of haemolymph were obtained by sectioning the forelegs and collecting the drop there formed. After dried, the samples were fixed by methanol and stained by Giemsa. Microscopical observation resulted in the characterization of five basic cellular types: prohemocytes, plasmatocytes, granulocytes, spherulocytes and oenocytoids. Moreover, undefined cell types, whose morphological patterns didn't have correlation with the characteristics cited for hemocytes, were found in low frequency. The change in the relative composition of the haemolimph was characterized by decrease of the number of... |

| The hemocyte composition of adults of Amblyomma cajennense (Fabricius, 1787) Koch, 1844 adults consisted of three basic cellular types: prahemocyte I (PR I), plasmatocyte (PL) and spherulocyte (ES II). Among the ixodids observed (A. cajennense; A. dissimile Koch, 1844; Rhipicephalus sanguineus Latreille, 1806; Anocentor nitens (Neumann, 1897) Schulze, 1937; Boophilus microplus Canestrini, 1887 and Haemaphysalis sp.) only A. cajennense was different in the adult hemolymph colour. It changed from amber to deep blue as the ixodid age advanced. This fact could be associated with the presence of hemocyanin in the hemolymph and points out the need to develop further investigations about the Ixodidae hemolymph pratein composition as well as the function of all... |
