Entomopathogenic fungi were collected from insects, belonging to orders Lepidoptera, Coleoptera, Hemiptera, Hymenoptera, and Diptera, with signs of infection. Single-spore colonies were identified based on morphological traits and ribosomal ITS sequences. The most commonly found fungi were Fusarium oxysporum Schlechtendal and Beauveria bassiana (Balsamo-Crivelli) Vuillemin. Isolation of Trichoderma atroviride Bisset, Aspergillus flavipes (Bainier and Sartory) Thom and Church, Aspergillus iizukae Sugiyama, Penicillium mallochii Rivera, Urb and Seifert, Penicillium adametzioides S. Abe ex G. Smith, and Mucor nidicola Madden, Stchigel, Guarro and Starks associated to insects is reported for the first time. Tests with B. bassiana isolates against Duponchelia fovealis Zeller (Lepidoptera: Crambidae), showed high larval mortality in vitro and in greenhouse, demonstrating its potential as biological control agent. Understanding the fungal microbiota from insects can provide promising isolates for use in integrated pest management programs. This is the first report characterizing the mycobiota in insects collected in strawberry crops, and evaluating the pathogenicity of B. bassiana against D. fovealis, a pest that causes severe losses to farmers.
