Pathogenicity of fungal isolates (Ascomycota: Hypocreales) against Peregrinus maidis, Delphacodes kuscheli (Hemiptera: Delphacidae), and Dalbulus maidis (Hemiptera: Cicadellidae), vectors of corn diseases

open access: yesMycopathologia, 2007
Preliminary screening assays were carried out on 17 isolates from five fungal species Beauveria bassiana, Lecanicillium muscarium, Metarhizium anisopliae, Isaria farinosa, and I. fumosorosea. The three most effective isolates against Peregrinus maidis (Hemiptera: Delphacidae) were B. bassiana CEP 147, CEP 150, and CEP 189.

Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

open access: yesEntomologia Experimentalis et Applicata
AbstractSince its first report in Brazil in 1938, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae) has been considered a secondary pest for maize. However, this insect has now become a key corn pest and the main phytosanitary threat to production in Brazil due to its potential to transmit pathogens.
