PAVONE, Domenico; DIAZ, Mayri; TRUJILLO, Lesbia  e  DORTA, Blas. A granular formulation of nomuraea rileyi farlow (samson) for the control of spodoptera frugiperda (lepidoptera: noctuidae). INCI [online]. 2009, vol.34, n.2, pp.130-134. ISSN 0378-1844.

A granular formulation of the entomopathogenic fungus Nomuraea rileyi (Farlow) Samson was evaluated against Spodoptera frugiperda (Lepidoptera: Noctuidae). The formulation consisted of 1mm particles of defatted corn germ (DCG) containing 10⁷ conidia/g. This preparation protected the conidia against UV radiation and killed 80% of S. frugiperda larvae in laboratory bioassays. It was shown that the fungus used DCG as a substrate for growth and sporulation, creating foci for further infection. This strategy has great potential for the formulation of fungal biocontrol agents, especially those with a high growth rate.
