Interactions of Spodoptera littoralis haemocytes following injection with the entomopathogenic fungi: Beauveria bassiana and Nomuraea rileyi.

This study compared the cellular interactions of Spodopteralittoralis haemocytes with two virulence-different entomopathogenic fungi: Beauveriabassiana and Nomuraearileyi. Using light and transmission microscopy, five types of haemocytes namely, prohaemocytes (PRs), plasmatocytes (PLs), granulocytes (GRs), spherule cells (SPs) and oenocytoids (OEs) were identified in the 6th instar larvae. PRs and PLs were found in the haemopoietic tissue.
