The functional role of the insect pathogen fungus Metarhizium anisopliae strain NCAIM 362 against the white grub cockchafer (Melolontha melolontha) larvae and southern European marshland pyralid (Duponchelia fovealis) larvae in a sweet potato cultivation was tested under greenhouse conditions. As a positive control, the effect of the same strain of M. anisopliae were compared with the effect of the synthetic insecticide alpha-cypermethrin. According to the results, alpha-cypermethrin was more effective against both the Coleoptera and Lepidoptera larvae, a lower number of surviving individuals as well as less damaged tubers were detected after the chemical treatment, compared with M. anisopliae.
