BACKGROUNDThe pear psylla, Cacopsyllapyri L. (Hemiptera: Psyllidae), is one of the most serious insect pests of pears in Turkey. In recent years, psyllid management has become increasingly difficult because of the development of insecticide resistance and the withdrawal of registered chemicals from the market. In this study, the field efficacy of an emulsifiable concentrate formulation of the entomopathogenic fungus, Metarhiziumbrunneum Petch strain F52 (Hypocreales: Clavicipitaceae), containing 5.5x10(9) conidiamL(-1), was evaluated against C.pyri in south-western Turkey (Antalya) in two consecutive years, 2010 and 2011.
