Boophilus annulatus is a species of tick commonly known as the southern cattle tick. It primarily infests cattle and is known for transmitting various diseases, including bovine babesiosis and anaplasmosis. This tick is typically found in warm, humid climates and can significantly impact livestock health and productivity. The life cycle of Boophilus annulatus includes several stages: egg, larva, nymph, and adult. Female ticks lay hundreds of eggs, which hatch into larvae that seek a host to feed on. After feeding, they develop into nymphs and eventually mature into adults, continuing the cycle. Effective control measures are essential to manage their populations and protect livestock.
