In this study, five morphological types of circulating hemocytes were recognized in the hemolymph of the adult sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), namely prohemocytes, plasmatocytes, granulocytes, adipohemocytes, and oenocytoids. The effects of the secondary metabolites of the entomopathogenic fungus Beauveria bassiana on cellular immune defenses of Eurygaster in...

Sunn pest is one of the most important cereal pests that affect both grain yield and quality of cereal in Iran. One potential control strategy is to use entomopathogenic fungi such as Beauveria bassiana Vuillemin as mycoinsecticide to control this pest. Naturally infested Sunn pests in Kermanshah province were collected and brought to laboratory. 10 isolates were selected for further analysis i...
