Overview

Demonstrates the infectivity of Blattambidensovirus incertum1 in Tenebrio molitor, suggesting important host-virus interactions.

Key Points

  • The aim is to validate Tenebrio molitor as a host for Blattambidensovirus incertum1 through infection studies and phylogenetic analyses.
  • Conducted metagenomic screening on larvae, pupae, and adults of Tenebrio molitor.
  • Isolated viral particles from infected mealworms and fed them to other mealworms to confirm infectivity.
  • Quantified TmDV relative abundance using Nanopore sequencing.
  • Reconstructed complete genomes of different TmDV genotypes and performed phylogenetic analyses.
  • All life stages of Tenebrio molitor tested positive for TmDV.
  • Infection showed asymptomatic characteristics with minimal impact on larval growth over 56 days.
  • Phylogenetic analyses revealed diversity among TmDV genotypes related to Blattambidensovirus incertum1.
