Larval, nymph and adult ticks remain on a single host for 18 to 35 days (3 weeks on average). Occasionally, they can also be found on marsupials, cats, feral pigs and dogs. Horses, camels, goats, sheep, llamas, vicuña, guanacos and alpacas can also carry cattle tick, but they are considered low-risk carriers. These are considered high risk cattle tick carriers. HostĬattle are the preferred host of cattle tick, however, heavy infestations may also occur on deer, bison and buffalo. Ticks moult from larvae to nymph and nymph to adult on the one host. Cost of biosecurity measures to prevent spread of the tick and possible disease into tick free zones.ġ host tick.Tick worry, which can significantly reduce cattle live-weight gain and milk production.Importance and impact of cattle tick infestation Previously known as Boophilus microplus, and then as Rhipicephalus microplus. Festoons may be difficult to see when a female tick is fully engorged. Festoons (short grooves around the margin at the posterior end of the tick) or no festoons.Eyes (can look like small hard blisters) or eyeless.The hard scutum covers the entire back of the male, but only a small part at the front in the female (allowing the rest of her body to expand when she takes a blood meal). The hypostome is the central mouthpart that pierces the animal for feeding. Length and shape of mouthparts, which includes the palps, which are either side of the hypostome.Photographs courtesy of Constantin Constantinoiuįeatures to assist in identification (see Figure 2). Example is unfed adult male and female dog ticks ( Rhipicephalus sanguineus) photographed from above (dorsal) and below (ventral). Body parts of male and female hard ticks. Engorging adult females are the largest life stage and the easiest to find and identify (Figure 1).įigure 2. Tick descriptions are based on adult ticks. Simple guide to identify significant ticks of cattle This will also assist with the removal of host tissue from the mouthparts, making identification easier. Severely dehydrated nymphs and adult ticks can be softened and restored for examination by placing them in a small quantity of dilute detergent for several hours. Ticks can be preserved in 70% alcohol or sent in in escape-proof containers. Taking the tick carefully between thumb and forefinger, as close to the skin as possible, and pulling gently, perhaps with a slight twisting motion, is usually sufficient for getting the tick off the host. If possible, extract ticks with undamaged mouthparts as these may be important for identification. Western Australia contact your local Department of Primary Industries and Regional Development (DPIRD) Biosecurity Officer. NSW should be taken without delay to the nearest Cattle Tick Control program office or any other NSW DPI office, or your Local Land Services. Northern Territory contact your Regional Livestock Biosecurity Officer (RLBO). Alternatively, you can use the following link to find a local DAF office. Queensland call 13 25 23 and state where you are from and ask to be directed to the local Biosecurity Officer (BO). This tick ID information can be used as a guide, but whenpositive identification is required ticks should be submitted to your local authority. Ticks of veterinary importance can generally be identified based on morphological features of the tick along with knowledge of host specificity. Photograph courtesy of Daktaridudu Wikimedia Commons.
