Introduction. The invasive gall midge, Procontariniamangiferae (= Erosomyia mangiferae Felt), is one of the mostimportant flowering pests of mango orchards worldwide. To achieve chemical inputreduction, developing integrated pest management (IPM) strategies using bio-control agentsis pertinent. Materials and methods. We tested the pathogenicity of twocommercial strains of the entomopathogenic fungi Beauveria onnon-diapausing 3rd-instar larvae of P. mangiferae. Results anddiscussion. Neither the Beauveria sp. commercial strain Betelnor the B. bassiana strain Bb 147 were effective, even though they provedtheir pathogenicity on the control, Galleria mellonella. Hypotheses toexplain the inefficiency of the two strains on P. mangiferae arediscussed. Conclusion. Other strains of Beauveria or otherentomopathogenic fungi or nematodes should be tested on diapausing and non-diapausinglarvae of P. mangiferae.
