| Abstract | ||
| The present inquiry meticulously grouped heart ticks, Rhipicephalus (Boophilus) annulatus and Rhipicephalus (Boophilus) sanguineus, based on dichotomous taxonomic key that includes number of criteria. Ticks demonstrated a sharp lateral angle of basis capitulum, stubby of palp pedicels, a large and straight cervical field, color of scutum was pale to dark, eye were convex slightly in both sexes, small mouthparts of male compared to female, genital cleft had U or V shape and other diagnostic criteria, etc. The specimens of Ixodid ticks had been detected to species level by stereoscope dissecting microscope according to the morphology. Rhipicephalus (Boophilus) collected from various numbers of ruminants taken from many places of Mosul city (Thmaarat, Baadush, Hmaydat, Souq Al-Ghanam, Damerji, Damerji Sagheer, Ryhana, Al-mawali, Ihlayla, Al-uboor, Btyasha, Dijlah, Al-Tanak and Zanazel). Molecular analysis by polymerase chain reaction for the ITS (5.8S rRNA) and S1 (16S rRNA) genes had been positive in all specimens, the refined amplicons had been shipped to the sequencing commercial company’s. This study intended on the morphological feature of Rhipicephalus (Boophilus) spp. to accomplish guideline observer with photographs taken by dissecting microscope which were approved by phylogeny of two isolates of R. annulatus and R. sanguineus, OR534233 and OR759793 respectively. Convergence rate betwixt my isolate and those of Egypt, Cameroon, South Africa, Pakistan, India, Thailand, China and USA was 97.80%-100% whereas phylogenetically showed that each isolate of two Rhipicephalus spp. fell inwardly one clade together with isolates of the countries mentioned above. | ||
