Investigation of the naturally occurring pathogens of these exotic pests revealed that both are attacked by Beauveria caledonica, a species originally isolated and described from soil in Scotland. The isolates in New Zealand were identical in morphology and conserved DNA region (rDNA, elongation factor a) sequence to isolates held in the USDA-ARS insect pathogens culture collection. In bioassay, the B. caledonica isolates were highly pathogenic to adults of H. ligniperda and larvae of Tenebrio molitor. Sporulation. was observed on cadavers, confirming the species can utilise the cadavers. As both species were likely to have been introduced to New Zealand from Europe, a search was made for B. caledonica in the northern UK and Ireland. The fungus was found as a naturally-occurring pathogen of the weevil pest, Hylobius abietis (Curculionidae: Scolytinae), developing in spruce and other beetles in forests in both regions.
