Entomopathogenic fungi of genus Cordyceps are distributed across the globe but especially prevalent in Asia where they have historically been used in traditional Chinese medicine. While host ranges vary between species, the majority belongs to orders Coleoptera and Lepidoptera and includes both larvae and adults. Cordyceps spp. have been explored as biological control agents for the management of agricultural pests such as moths and whiteflies and continue to yield promising results. Examples of commercially available Cordyceps containing insecticides include Crysokill (Prima Agro Tech, Indonesia) and PFR-97® (Certis Biologicals, USA). Cordyceps farinosa (prev. Isaria farinosa and Paecilomyces farinosus) has been identified in Icelandic birch woodland and heathland soils. However, examples of C. farinosa host-pathogen interactions in Icelandic ecosystems remain largely undocumented. Here we report recent observations of Cordyceps farinosa infection of adult Phratora vitellinae (brassy leaf beetle, prev. Phyllodecta vitellinae, is. asparglytta, smjörbubbi) on both Populus and Salix species in SW Iceland. This is, to our knowledge, possibly the first record of a Cordyceps-Phratora host-pathogen interaction, although it remains unclear if C. farinosa was the primary cause of death.
