In all kinds of flies, there are bloodsucking flies are ectoparasites insects that feed on blood of other animals or people, through mouthparts biter and a device having the head end, with biting their victims.
A group of twenty species of African fruit flies are called Glossina gender equally abundant in forests, along rivers and lakes in Central Africa. These species are studied flies that transmit a deadly parasite that causes sleeping sickness in people and Nagana in cattle, horses and goats in southern Africa. Parasites tripanosomasson absorbed by the insect bites when the person concerned, introducing other people and going biting. When animals are continuously affected by nagana can reach immunized against it. This disease is one of the most devastating of all the African continent, especially in the central area, with 80% of deaths in the affected victims, killing annually to three million head of cattle. All this, it affects the poorest people on the planet, creating an economic loss in the production of meat and milk, and the control and elimination of the disease.
The tsetse flies belong to the group of hematágafas flies.
The sand fly
Tiny and biting are important vectors of several human diseases, including kala-azar or Dumdum fever, button Orient and tertiary fevers. These flies are native to tropical and subtropical regions. Females have a piercing mouthparts and feed on the blood of mammals, picándoles especially at night, unlike males feed on plant nectar. They grow in moist, dark and mossy land. The species of fly sand is best known transmitting the virus of the disease known as Tertiary and Fever Fever Changres. Symptoms are similar to dengue, but is rarely fatal, but disabling their victims from one to nine days. It occurs mainly in Asia Minor, South Asia and Europe and North Africa. This fly is a carrier of the disease once ingested blood contaminated by the virus. It is further believed that the female transmits the virus to their babies.
These small flies transmit many diseases by their bite.
It is an insect of the order Diptera well known the pain of their bite. Only females can bite to feed on blood, they need a high protein food, to meet the needs of nutrients in the egg production. In their search for food they are guided by silhouettes and scents; therefore the female horseflies are attracted before by people wearing dark clothes and animals which layer is equally dark, especially if actively transpire that by other people or animals carrying light colors. The males feed on plant juices. The larvae are deposited in waterlogged soil, where they feed on other insects. In African areas Loasis transmit some species, affecting millions of people.
Females are the biting horseflies.
The stable fly
Both males and females feed on blood sucking animal farm, inside the premises of intensive animal production. Abundantly they established around the feeders, resting areas of dairy cattle, and stables. They prefer sunny, outdoor areas, such as stacked hay, manure mixed with straw, etc. They not usually breed inside buildings. When fed flies are usually placed in the lower parts of the animals, in particular in the lower half of the legs. These flies attack people with the same ease as livestock.

A native of South America, has been extended by various areas. For playback you need only manure from cattle, which lays its eggs. When feeding of cattle, which can be day or night, causes irritation and discomfort, preventing feed and rest in peace. This produces an effect of weight reduction and milk production in cows. The use of pest control methods to eradicate these flies is very useful and eliminate significant economic damage.
This fly is originally from South America, but in recent years has spread to other areas.
