Abstract
Here we show that a bacterial endosymbiont, Regiella insecticola, protects pea aphids (Acyrthosiphon pisum) from the aphid-specific fungal entomopathogen Zoophthora occidentalis but not from the generalist insect fungal pathogen Beauveria bassiana. This finding highlights the complex influence of fungi on the dynamics of this economically important agricultural pest.
摘要
在这里，我们表明一种细菌内共生体，Regiella insecticola，可保护豌豆蚜（Acyrthosiphon pisum）免受蚜虫特异性真菌病原体 Zoophthora occidentalis 的侵害，但不能免受广谱昆虫真菌病原体绿僵菌（Beauveria bassiana）的侵害。这一发现突出了真菌对这种具有重要经济意义的农业害虫动态的复杂影响。
