Pediculus humanus

The two species that belong to this group include Pediculus humanus capitis (head louse) and P. humanus corporis (body louse). The eggs (or nits) remain firmly attached to the hair, and in about 10 days the lice hatch to form nymphs, which mature in 2 weeks. The lice become attached to the base of the hair follicle and feed on the blood of the host.10 Pubic or crab lice are found on the hairs around the genitals, but may occur...

Permethrin is toxic to Pediculus humanus, Pthirus pubis, and Sarcoptes scabiei. Less than 2% of an applied dose is absorbed percutaneously. Residual drug persists up to 10 days following application.

Three species of lice occur as parasites on humans. These lice are blood suckers, and they can be disconcertingly abundant under unsanitary conditions. The human louse, Pediculus humanus, occurs as two races, which feed on different parts of the body. The head louse, capitis race, occurs in the hairs of the head, to which it attaches its whitish eggs, also known as nits. The body louse corporis race, also known as the cootie, feeds on the human body, and hides and lays its... 

Head lice (Pediculus humanus capitis) are small wingless Insects that live on and feed on blood from the human scalp. 

Malathion is a pediculicide that inhibits cholinesterase activity. It is used in the treatment of head lice (Pediculus humanus capitis) and their ova of the scalp hair. 

Two parasitic organisms that cause common topicai infections are Sarcoptes scabiei, which is responsibie for scabies, and Pediculus humanus, which is responsible for lice infections. 

It is not certain when people first started wearing elothes. Scientists estimate that this happened more than 100,000 years ago, beeause the body louse (pediculus humanus humanus) apparently diverged from the head louse (pedi-culus humanus capitis) at that time. The first elothes were made from natural materials animal skin and furs, grasses and leaves and the first needles are recorded about 30,000 years ago.
