Hemócitos fagocitários em larvas de Diatraea saccharalis (Fabricius) (Lepidoptera, Pyralidae)

Phagocytic hemocytes in larval of Diatraea saccharalis (Fabricius) (Lepidoptera, Pyralidae)

Resumo

The ultrastructural observation of the hemocytes of D. saccharalis larvae showed different hemocyte tvpes in various stage of interaction with microorganisms, which were interpreted as bacteria. The microorganisms were observed either free in the hemolymph or into the insect hemocytes. The bacteria were detected mostly into lhe granulocytes and plasmatocytes: the spherule cells and the oenocytoids also presented intracytoplasmic microorganisms, but less frequently. The fagocytic capacity of the different hemocyte tvpes is discussed.
