Identification and prevalence of ticks infesting small ruminants of Fort Munro region in South Punjab, Pakistan.

ABSTRACT

Fort Munro is a hill station in Southern Punjab the residents of whom are heavily dependent upon livestock for their living but ticks are a big treat for the livestock. The purpose of this study was to ascertain the tick infestation among the small ruminants of Fort Munro. Ticks (N = 273) were collected from 333 animals (165 goats and 168 sheep) during August and September 2022. Two tick genera Hyalomma and Rhipicephalus were identified. Rhipicephalus was most abundant tick genera (78.02%) followed by Hyalomma (21.98%).Tick distribution significantly varied with the host Rhipicephalus ticks were more frequently infesting goats while Hyalomma were more common on sheep. For both hosts, tick infestation varied with the sampling sites and male animals were significantly more infested than females. Five tick species were infesting goats with the following relative abundance Rhipicephalus (R.) senegalensis (39.20%) > R. sanguineus (36.8%) > R. appendiculatus (10.40%) > R. turanicus (8%) > R. guilhoni (5.6%). Rhipicephalus senegalensis (41.22%) was also the most common tick species infesting sheep followed by Hyalomma (H.) marginatum (29.73%), R. guilhoni (18.24%), H. dromedarii (5.41%) and H. impeltatum (5.41%). Male ticks very more abundantly on both goats and sheep than female. Distribution of Hyalomma species also varied between the sampling sites. In conclusion, we are reporting the infestation of 3 Hyalomma and 5 Rhipicephalus in small ruminants of Fort Munro. The data generated through this study will help in developing appropriate tick control in the study area and will add to the existing knowledge regarding tick species that are infesting the small ruminants of Pakistan.
