Phylogenetic and Ultrastructural Characterization of Bed Bugs in the Southwest of Iran
Bibliographic record
Abstract
Abstract Background: Bed bugs belong systematically to Order Hemiptera; Suborder Heteroptera; Family Cimicidae are of public health importance as ectoparasites of mammals and birds, however, only a few species are the putative ectoparasites of humans. Bed bugs are a wingless bloodsucking hemipterous bug (Cimex spp.) sometimes infesting houses and especially beds and feeding on human blood. Correct species identification is very important in order to design targeted strategies for surveillance and control of bed bugs in a given area. Methods: Adult bed bugs were collected from houses located in the southwest of Iran. The specimens were morphologically identified to the species level and then confirmed using molecular methods. Results: The mtDNA 16S rRNA sequences obtained from the specimens, and phylogenetic tree derived, showed that all the sequences belong to Cimex hemipterus. The Disparity Index among results showed that all the specimens were of a heterogeneous population. To the best of our knowledge, the leg structure of this species has not previously been documented and this is the first report of an open-closed rack system in the legs of C. hemipterus.Conclusions: Previous studies claimed that C. lectularius is the abundant species of Cimicids in Iran. But this investigation showed that C. hemipterus is the prevalent species in the southwest of Iran.

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.
