Cattle Tick Control
The cattle tick (Rhipicephalus microplus previously Boophilus microplus) is a serious economic pest of the Northern Territory cattle industry. Livestock production can be significantly reduced if cattle tick infestations are not managed effectively. The cattle tick is also responsible for transmitting other disease causing organisms to cattle. The cattle tick can transmit blood-borne tick fever organisms which cause sickness and death in cattle.
The cattle tick control program aims to contain cattle tick within the Cattle Tick Infected Zone and minimise the risk of spread within the Control Zone and to the Free Zone and also to minimise the spread of Parkhurst cattle tick. The risk of tick fever outbreaks and strategies required to prevent tick fever are determined by the distribution of cattle tick. Movement conditions apply to stock movements within the Territory and interstate to manage these risks.

- Parkhurst Cattle Tick
Parkhurst cattle tick are cattle ticks which are resistant to certain chemical products. These include the synthetic pyrethroid (SP) and organophosphate (OP) group of chemicals such as Bayticol, Barricade S, Blockade S and Tixafly products.
Parkhurst cattle tick was first detected on cattle stations in the Darwin region of the Territory in the late 1990's. A recent survey to determine the current distribution has shown that many properties in the Darwin Region are now infected with the Parkhurst tick.
On May 1, 2011 a new Parkhurst Infected Zone was introduced to try and contain the Parkhurst ticks to a known infected area. This area extends from Darwin to Pine Creek and east to the boundary of Kakadu National Park. Movement restrictions apply for stock moving out of the Parkhurst Infected Zone.
