Abstract

Otiorhynchus sulcatus, known as the vine weevil, is a polyphagous pest that causes economically important damage to horticultural crops worldwide. The entomopathogenic fungus Metarhizium brunneum is widely used to control this pest. Little research has investigated variation in susceptibility to this pathogen between vine weevil populations at different locations. This study addresses this knowledge gap by comparing survival rates of larvae from adults collected in two UK areas when treated with M. brunneum. Larvae from these locations did not differ in their susceptibility, suggesting that location per se may not affect the efficacy of M. brunneum against vine weevil larvae.
