CUNHA, Franklin M et al. Hemocyte characterization of Nasutitermes coxipoensis (Holmgren) (Isoptera: Termitidae) workers and hemocyte evaluation after parasitism by Metarhizium anisopliae. Neotrop. entomol. [online]. 2009, vol.38, n.2, pp.293-297. ISSN 1519-566X.

We aimed to characterize the morphology and ultrastructure of hemocytes of Nasutitermes coxipoensis (Holmgren) workers and to quantify the cell types 24h, 48h and 72h after inoculation with Metarhizium anisopliae. Six hemocytes types were identified, plasmatocyte, granulocyte, spherulocyte, prohemocyte, adipohemocyte and eonocytoid Hemocytes did not present any morphological alteration at the several observation periods, but they did have a change in their abundance, as observed for spherulocytes, adipohemocytes and eonocytoids at all intervals, and for plasmatocytes and granulocytes at 48h after host inoculation. We argue on the possible reasons and implications of the observed changes.

Keywords : Ultrastructure; entomopathogenic fungus; insect hemocyte.
