Abstract The spatial distribution of chewing lice Bovicola ovis on their hosts was examined in Polypay and Columbia ewes initially artificially infested on the midside or the neck. Polypay ewes had higher densities of lice than Columbias bovocola most inspections but there was little effect of infestation point or mating on either numbers or the distribution of lice. Densities on the head were also high at times and peaked later than overall louse densities. The presence of the louse causes the host to lick itself excessively thus causing abrasions and hair loss.

It was concluded that the degree of wetting attained at dipping was an important factor in achieving eradication of sheep lice.

Efficacy against sheep lice (Bovicola ovis) and fleece wetting of six shower dip preparations.

Maturation from hatching to adulthood takes about two to three weeks. The eggs hatch and the cycle repeats. Because the louse is so prominent bovicoka North America, very much of the cattle are affected and must be carefully treated and looked after. Once the louse is mature, it begins to look for a mate. The licking from the cattle and the presence of the louse both cause these health problems to occur. The life of the louse is hemimetabolousmeaning the young of the louse resemble the adult and bovcola the same habitat, behavior, and diet.

One method of control attempted is through the use of the fungus Metarhizium anisopliae. In the second year, half of the ewes were mated and lice were counted at 26 body sites on the resulting lambs.

Without the host providing both food and shelter, the louse would die. Inspections for lice were conducted until 9 months after dipping. These lice have spiracles located on the edges of each segment of the abdomen to allow the lice to breathe. These antennae commonly have three segments. These lice are obligate parasites, meaning they require the host to survive. These lice are composed of three major body regions: In the latter case, please turn on Javascript support in your web browser and reload this page.

Groups of 20 sheep infested with lice were treated with products containing either alphamethrin, cyhalothrin, diazinon or diazinon plus piperonyl butoxide and rotenone, formulated as emulsifiable concentrates, and with products containing either coumaphos or magnesium fluorosilicate, formulated as wettable powders.

Densities of lice were determined at 69 body sites in eight body regions at approximately monthly intervals for 2 years. This page was last edited on 16 Februaryat Retrieved from ” https: Boviola do, however, lack the maxillae that are common to most insects that chew their food.

Whilst on the host, the louse feeds upon the hair, skin, and secretions that are present. The louse spends eight days in its egg, or nit, that had been laid on the host. There are no known cases of the louse transmitting any kind of disease causing agent. The presence of the louse can also result in reduced milk production and poor weight gain.
