Geographic Origin May Not Influence Vine Weevilotiorhynchus Sulcatus(Fabricius) Susceptibility To The Entomopathogenic Fungusmetarhizium Brunneum(Petch)

Otiorhynchus sulcatus, known as the vine weevil, is a polyphagous pest that causes economically important damage to horticultural crops worldwide. The entomopathogenic fungusMetarhizium brunneumis 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 withM. brunneum. Larvae from these locations did not differ in their susceptibility, suggesting that locationper semay not affect the efficacy ofM. brunneumagainst vine weevil larvae.
