SCIENTIFIC NAME for CATTLE LICE: Damalinia bovis formerly Bovicola bovis
SPECIES: 4 types of sucking lice, short-nosed cattle lice, long-nosed cattle lice, little blue lice, and cattle tail lice, 1 type of biting lice, biting lice
ORIGIN/PROMINENCY
The 5 species listed previously are found on cattle in North America.
The lice are most prominent in the colder months.
LIFE-CYCLE
Lice produce eggs called nits, nits turn to nymphs after about two weeks. These nymphs are what hatch out of the egg. They look similar to an adult, the only thing that a nymph does not resemble is its egg producing ability. The life-cycle from an egg, to a nymph, and to an adult is 3-4 weeks (during colder months). It can not survive off of its host for very long.
SYMPTOMS
HOW IS IT TRANSMITTED?
Lice is transmitted by contact from one animal to another. “Up to one or two percent of the cattle in a herd can carry a high load of lice, even in the summer when high temperatures reduce the number of lice.” Carriers usually consists of cattle who are bulls or cows who are of poor body condition.
