First report of Akanthomyces dipterigenus (Hypocreales: Cordycipitaceae) in the Iberian Peninsula

Abstract

Akanthomyces dipterigenus is a species of entomopathogenic fungus (Hypocreales: Cordycipitaceae) that has undergone several reclassifications in recent decades. While it has been utilized for biological control, information on its distribution and ecology remains limited. Furthermore, this species has only recently been reported in continental European countries. Our research provides the first report of A. dipterigenus in the Iberian Peninsula. Fungal isolation was achieved via a modified baiting technique featuring Rhopalosiphum padi aphids. Results suggest that the isolation methodologies and ecological traits of the fungus may either aid or hinder its detection. Additional research is necessary to assess its distribution throughout the Peninsula and neighbouring European countries, and to examine its potential as a biological control agent.
