As already mentioned, head lice feed on blood. And
they have a wonderful appetite. During the day one louse can
suck from 0.5 to 0.65 mg of blood. In 24 hours the insect eats
4-5 times, and the process of food consumption on average takes 5-10 minutes.
This is due to the special structure of the body lice, it is absolutely not
adapted to prolonged fasting. As a result of lack of food
even a short period can lead to the death of an insect.

At all stages of development, the head louse feeds only
human blood. Because of its particular structure, the parasite
able to pierce the skin and pump human
blood in your belly.

REFERENCE! It is believed that lice are capable
absorb hair and microparticles of the skin, but it does not have under itself
reason, as it is proven that these parasites cannot digest
solid food.

However, other members of the louse family may eat down,
skin particles and hairs.

Thus, the lice on the human head feed
only by blood, except for the larval period. Nits up
full maturation does not eat anything at all.

Features of life and reproduction of parasites

Reproduction is carried out in the same place where lives
an insect, that is, on the body of the host. Conditional process
reproduction is divided into the following stages:

  1. The time when mating occurs male and female
    individuals.
  2. Next is the fertilization of the egg.
  3. After that, the female lays eggs.

Lice eggs, or, as they are called, nits, are surrounded
dense shell, which damage is extremely
is difficult. This shell helps the embryos stay
under reliable protection from environmental exposure. During the period
of its life, female lice can reproduce light from several
tens to several hundred eggs. Due to such increased
fecundity type lice still exists safely.

REFERENCE! After the larva hatch,
there is its triple molt until it turns into
adult

With lice are associated with various features that are inherent
these parasites:

  1. To continue her race, one is enough for a female
    meeting with the male. After fertilization, his seed is stored in
    louse belly, after which she can
    lay eggs.
  2. Louse hardly tolerates low temperatures.
    So, already at +20 degrees, it stops multiplying, and at -5
    degrees – perish. But the heat also has a negative effect on
    parasites. At a temperature of +50 degrees, the insect dies in
    for half an hour.
  3. Being on the human body, the louse chooses the warmest
    places. If it is a clothes louse, then its habitat
    armpits become, the lower back and neck area. Head
    head lice settle on the back of the head and behind the ears.
  4. If a person tries to wash off lice with water, then this is his
    will not work, as parasites cling tightly to the hair
    and block the airways on the sides.
  5. Usually lice settle on the head of one person and
    relocate extremely reluctantly.

IMPORTANT! Usually from the day of infection and before
manifestations of lice passes a few weeks. To discover
lice, first you need to check the occipital region and place
behind the ears. This is the favorite areas of stay of head parasites.

  5. Sometimes boils, ulcers and deep
    scarring.
  6. Rarely a generalized allergy develops, which
    besides skin rash, headache, nausea and
    deterioration of the general condition.
  7. If there are many parasites on the body and head, this affects
    human well-being, causes various complications and may even
    lead to death.

bites, then infection can penetrate into the wounds over time
leads to the formation of ulcers on the scalp.

    a close look at the folds of clothes you can see a lot
    small points, this is a louse.
  4. Just like head lice, females are larger than males and
    can reach a length of 4 mm.
  5. In a hungry state, the body color of these lice
    yellow, when saturation with blood becomes rusty
    shade.
  6. Nits are very small, up to 0.5 mm, so
