Haemaphysalis spp.
Rabbit Tick, Bird Tick


General Description:
Small, inornate tick without eyes. Festoons are present. Palpi are short and conical with notable lateral projections from second segment.

Life Cycle:
Haemaphysalis species are three-host ticks. Unfed ticks may survive as long as 300 days.

Location:
Skin on all parts of the host.

Geographical Distribution:
Worldwide.

Significance:
In addition to annoying cattle, species of Haemaphysalis may transmit cattle tick fever, anaplasmosis, and Q fever. Paralysis may also occur.

Effect on Host:
Ticks irritate the host, causing tick worry (scratching, rubbing, and Iicking), decreased feed intake, and unthriftiness. Blood sucking of large infestations may bring on tick anemia. Paralysis by ticks causes death unless ticks are removed in time. Anaplasmosis and cattle tick fever are transmitted by Haemaphysalis ticks.

Diagnostic Information:

Adults on many parts of the animal may be identified.

Control:
Treatment with chemicals.
