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 () , , , , , , and . The predominant tick species recorded is () . 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 ( < 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.
蜱是吸血节肢动物，蜱传播的疾病给养牛业造成了数十亿美元的损失，因为蜱能够成为多种病原体的传播媒介。本文针对阿尔及利亚东北部吉杰尔地区牛的性别、年龄和品种，对硬蜱雌性与雄性的侵染率（患病率和强度）进行了识别和比较。2019年夏季（6月、7月和8月）共筛查了53头受侵染的牛，并人工采集了1214只蜱，根据其形态进行了鉴定。确定有七种蜱侵染牛：即（）、、、、、、和。记录到的主要蜱种是（）。蜱侵染强度随年龄的最大值出现在3至4岁和5至6岁之间（每头牛39只蜱）。研究表明，雌性和雄性侵染患病率的比较因牛的性别和品种而存在显著差异。此外，在比较蜱的性别时，仅蜱侵染强度随牛年龄的变化具有显著性（<0.05）。本研究还为基于蜱交配策略制定积极的控制计划提供了数据，以管理阿尔及利亚吉杰尔地区牛身上的蜱。
