Characterization of the Tuta absoluta virome reveals higher viral diversity in field populations
Bibliographic record
Abstract
• The RNA virome of Tuta absoluta was described for the first time. • Ten novel RNA ISVs were identified in worldwide T. absoluta populations. • Plant-infecting viruses and mycoviruses were also detected in the insect pest. • Field-collected samples exhibited a greater ISVs diversity than laboratory samples. A significant number of insect-specific viruses (ISVs) have been discovered in agriculturally important insect pests, facilitated by high-throughput sequencing (HTS). Despite its global impact on tomato crops, the RNA virome of the South American tomato pinworm, Tuta absoluta , remains uncharacterized. In this study, we utilized meta -transcriptomics and bioinformatic approaches to discover the RNA virome of T. absoluta across worldwide populations. We identified ten novel ISVs, classified into eight groups: Nidovirales , Bunyavirales , Mononegavirales , Virgaviridae , Iflaviridae , Nodaviridae , Solemoviridae , and Phasmaviridae . Notably, no core virus was consistently present across the studied populations, and field-collected samples revealed a greater diversity of ISVs compared to those from laboratory samples. In addition, we detected plant-infecting viruses and mycoviruses associated with the pest. This study represents the first description of the RNA virome associated with T. absoluta , providing valuable insights into its biological and ecological interactions. It also lays the foundation for future studies aimed to clarify the biological roles of ISVs.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
