Ability of Cellulose Acetate and Polyacrylamide Enzyme Electrophoresis to Separate 13 Species of Phlebotomine Sand Flies (Diptera: Psychodidae) from Venezuela
Bibliographic record
Abstract
The detection of cryptic species by biochemical methods indicates that within the phlebotomine fauna morphological data are not always adequate for species diagnosis. Cellulose acetate and polyacrylamide enzyme electrophoresis methods were compared for their effectiveness in identifying 13 species of Venezuelan phlebotomine sand flies and resolving alleles. Eight diagnostic loci unambiguously separated these 13 species of sand flies. Although acrylamide was as effective as cellulose acetate in species separation, differences were detected in the resolution of some alleles. Cellulose acetate identified more alleles at Ak and Fum, and resolved better at Pgm, whereas acrylamide identified more alleles at Gpi, Mdh, and Me. Therefore, erroneous species diagnoses may occur, if diagnostic loci detected by one technique are used by a second technique without adequate reference standards.

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.
