Cattle tick

Systematic position: Rhipicephalus annulatus belongs to the phylum Arthropoda, class Arachnida, order Ixodida, and family Ixodidae. It is a major ectoparasite of significant economic importance in global veterinary medicine and animal husbandry.

Biology and life cycle: This tick is a one-host parasite. All developmental stages, including larva, nymph, and adult, occur on a single individual animal. Engorged females drop to the ground to lay thousands of eggs in the vegetation, ensuring the survival of the next generation of larvae.

Damage and harmfulness: The primary impact of Rhipicephalus annulatus is its role as an obligate vector for protozoan parasites, specifically Babesia species, causing cattle fever. Infested animals suffer from severe anemia, weight loss, and secondary infections caused by tick bite lesions.

Host range: The species primarily targets domestic cattle (Bos taurus and Bos indicus). While it is not a direct agricultural crop pest, its presence restricts the utilization of vast grazing lands, making it a critical threat to the livestock sector in temperate and tropical regions.

Control measures: Successful management requires a strategic approach:

• Applying acaricides via dip tanks or spray races;
• Utilizing pour-on treatments for long-lasting protection;
• Implementing pasture rotation to starve emerging larvae;
• Vaccination programs against tick-borne diseases in highly endemic areas.
