Potential of entomopathogenic fungi and nematodes against Drosophila suzukii in laboratory assays

Abstract: The effect of several entomopathogenic fungi (EPFs) and entomopathogenic nematodes (EPNs) autochthonous strains against D. suzukii individuals (larvae, pupae and adults) was evaluated in laboratory assays. Results showed a moderate effect against D. suzukii larvae and adultsand an higher virulence against pupae. Furtheremore, the deterrent effect on D. suzukii oviposition activity of several EPFs strains was evaluated in laboratory conditions (no-choice and double-choice test), in comparison with other mineral compounds (potassium silicate and kaolin). Results reveals promising perspectives for the biological and integrated management of this pest.
