Identification and incidence of hard tick species during summer season 2019 in Jijel Province (northeastern Algeria).

Ticks are haematophagous arthropodsand tick-borne diseases causes billions of dollars in losses in the cattle industry because of the ability of ticks to be vector for many pathogens. This paper identifies and compares the infestation rate (prevalence and intensity) of females of hard tick species compared to males with respect to sex, age and breed of cattle in the region of Jijel, northeastern Algeria. A total of infested 53 cattle were screened and 1214 ticks were collected manually during summer 2019 (June, July and August) and identified based on their morphology. Seven tick species were identified as infesting the cattle: viz. Rhipicephalus (Boophilus) annulatus, Rhipicephalus bursa, Rhipicephalus sanguineus, Hyalomma marginatum, Hyalomma lusitanicum, Hyalomma scupense, and Hyalomma anatolicum. The predominant tick species recorded is Rhipicephalus (Boophilus) annulatus. The maximum intensity of tick infestation as a function of age is between 3 and 4 years and 5 and 6 years (39 ticks/cow). The study shows that the comparison between the prevalence of infestation in females and males is significant as a function of sex and breed of cattle. In addition, only the intensity of infestation as a function of the age of the cattle, when comparing the sexes of the ticks, is significant (p < 0.05). This study also provides data for the development of an active control plan based on tick mating strategies for the management of ticks in cattle in Jijel, Algeria. © Indian Society for Parasitology 2020.
