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. GRAPHICAL ABSTRACT

地理起源可能不会影响象鼻象鼻虫 Otiorhynchus sulcatus (Fabricius) 对昆虫病原真菌 Metarhizium brunneum (Petch) 的易感性

摘要 Otiorhynchus sulcatus，被称为葡萄象鼻虫，是一种多食性害虫，对世界范围内的园艺作物造成重要的经济损失。昆虫病原真菌绿僵菌被广泛用于防治这种害虫。很少有研究调查不同地点的葡萄象鼻虫种群之间对这种病原体的易感性变化。本研究通过比较在英国两个地区收集的成虫幼虫在用 M. brunneum 治疗时的存活率来解决这一知识差距。来自这些位置的幼虫的易感性没有差异，这表明位置本身可能不会影响 M. brunneum 对抗藤象鼻幼虫的功效。图形概要
