The sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is the most important insect pest of wheat and barley. The population management of this pest is of major concern to wheat producers. One of the potential control strategies is to use entomopathogenic fungi. This study evaluates the pathogenicity of the fungus Metarhizium anisopliae var. major (Metchnikoff) Sorokin (Hypocre...
Sunn pests, which can cause significant yield losses on wheat and barley, are one of the pests whose population levels should be followed. Overwintering areas, have an important place in biology insect, provide advantage development biological or integrated control with entomopathogenic fungi. Entomopathogenic fungi most agents reducing overwintering areas. In this study, Lecanicillium psalliot...
