Molecular footprint of <i>Frankliniella occidentalis</i> from India: a vector of Tospoviruses
Bibliographic record
Abstract
The western flower thrips, F. occidentalis is a vector of Tospoviruses and native to Western North America and Mexico. The present study is based on collected F. occidentalis specimens from Karnataka state in southern India and morphologically identified through available keys. The generated DNA barcode data show 99–100% similarity with the database sequences of F. occidentalis. The phylogenetic analysis (NJ, ML, and BA) shows three distinct clades of F. occidentalis in the present dataset with high bootstrap supports and posterior probabilities. The K2P genetic distances further depicted high similarity of the generated sequences from India and Netherlands. The Clade-1 (India + Netherlands) also shows a close relationship with Clade-2 (Kenya) rather than Clade-3 (Canada + USA). This study recorded the first genetic footprint of F. occidentalis in India and indicated the gene flow from the Netherlands to India. The similar molecular techniques may help to detect the invasion of many alien species in the near future and assists the quarantine regulations to protect the native ecosystem.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
