Genetic Structure of <I>Aedes vexans</I> (Diptera: Culicidae) Populations from Central United States Based on Mitochondrial ND5 Sequences
Bibliographic record
Abstract
Aedes vexans (Meigen), the vexans mosquito, is a species that prefers mammalian hosts and is a vector of West Nile virus (family Flaviviridae, genus Flavivirus). It is one of the most widespread pest mosquitoes in the world and North America, and it is commonly found in southern Canada and continental United States. Population structure of this species in Kansas was examined using DNA sequences of a 423-bp region of the mitochondrial NADH dehydrogenase subunit 5 (ND5) gene, relative to three other states. From the 54 Kansas samples, a total of 39 nucleotide positions were polymorphic, with 34 haplotypes. Of the 34 haplotypes, 22 (79%) were not shared among populations. The average haplotype diversity (0.953) from 11 Kansas populations indicated a high level of genetic diversity in Ae. vexans. Among the Kansas, South Dakota, Texas, and Louisiana samples, a total of 40 haplotypes were observed. Analysis of molecular variance was conducted on the resulting haplotypes for all populations and no geographical structure was observed among populations by using isolation-by-distance tests. This first genetic study of Ae. vexans provides evidence that there is a large amount of haplotype variation within and among populations, and gene flow occurs across broad geographical areas in this species.

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.
