Therefore, safer pest management options are needed to supplement current non-chemical control techniques, especially for controlling Thaumatotibia leucotreta Meyrick (False codling moth, FCM), an important phytosanitary pest. A national survey was initiated in 2023 to identify native entomopathogenic fungi (EPF) from Ghanaian farms. Seven Metarhizium isolates were recovere...
