Morphometric Study on Male Specimens of Hyalomma anatolicum (Acari: Ixodidae) in West of Iran
,
Abstract
Background: Hyalomma anatolicum is the well-known hard tick, which is one of the most important livestock and human pathogens vector, wide range in host and distributed in all over the Hyalomma geographic fauna as well as in Iran. Taxonomy of the Hyalomma ssp. is debatable whereas their identification is a problematic work. The reasons for this claim is time consuming Delpy’s researches in Iran also Schulze School, Feldman-Muhsam and the Russian tick workers. We would like to understand morphometric variation in the field collected H. anatolicum in Iran also validating some morphologic quantitative and qualitative characters.
Methods: A total 247 field-collected tick specimens from different geographical regions in west of Iran includes Khuzestan and Lorestan Provinces were studied. The morphologic characters of the ticks were measured by the calibrated stereomicroscope armed scaled lens. The measurements were analyzed using SPSS for windows, version 16 on an IBM PC, so varied shapes of species in different geographic regions were drawn by the aid of a drawing tube connected to a light stereomicroscope.
Results: One way ANOVA test revealed significant differences among the quantitative parameters in five zones (P< 0.001) also each zone to other zone by Post Hoc Tests e.g. LSD. No significant differences in the lateral grooves length/conscutum length ratio parameter were found.
Conclusion: Morphometric variation in Hyalomma spp is poorly studied. The variation in range and quantity of the morphometric parameters of H.anatolicum underlies that the correct recognition and key construction for Hyalomma species dependes on a complement morphometric study on the other species.
