Oral microbiome is related to lepidopteran herbivore performance by lignin degradation.

ABSTRACT: Microorganisms associated with insects play crucial roles in mediating the host plant adaptation of their insect hosts. Although oral microbiota are the primary interface with ingested plant material, we still poorly understand their diversity, their function, and their ecological relationship with insect performance. Here, we investigated the diversity and function of the oral microbiota in two generalist lepidopteran pests (Spodoptera litura and Spodoptera frugiperda) feeding across three host plants (bok choy, peanut, and maize). Plant species significantly influenced the diversity and composition of oral microbiota in both S. litura and S. frugiperda. Oral microbial communities from insects feeding on bok choy exhibited significantly higher Sobs richness and
