The black fly

The black fly elimination with drones

What is the black fly and what effects does it produce?

The black fly, whose real name corresponds to simulids (Simuliidae), they belong to the family of nematocerous diptera. Its size ranges from 2 to 5 mm) and its color is generally dark. They are characterized by having a stinging-sucking mouth, wings wide and short legs.

The black fly it's a real nightmare for people and livestock, because some species act as vectors of serious diseases.

Some 1.700 species and 41 subgenres are known.

  • The simúlidos (black fly) are a diptera between 2 and 5 mm in size
  • It is a real nightmare for people and livestock
  • They act as vectors of serious diseases
  • About 1.700 species and 41 subgenres are known
  • They live near streams, where they breed and where they attack mammals and birds most aggressively.
  • They look for highly oxygenated waters with a lot of organic matter in suspension, for a correct development of their larvae
  • They reject polluted waters. The improvement of our rivers has favored their spread
  • Their larvae are aquatic and live fixed on the stones and vegetation of those areas
  • Daytime habits, especially in hours close to sunrise and sunset
  • They are very good fliers, being able to reach 50 km from their birth zone

Reproduction and habitat of the black fly

Su natural habitat usually near streams, where they breed and attack mammals and birds most aggressively that are in the area. They look for highly oxygenated waters with a lot of organic matter in suspension, for a correct development of their larvae. Reject water pollutionFor this reason, they have spread more easily throughout all European rivers, which have generally improved their quality.

Their larvae are aquatic and live fixed on the stones and the vegetation of those areas where the water runs. Their habits are daytime, especially at first and last hour of the day, and they are very good fliers, arriving in favorable conditions to reach a radius of action that can reach 50 km from the place where they were born. Distance that will be much more frequent in females, when they go in search of their victim.

Grown ups have a tendency to form clouds or swarms, especially during sunrise and sunset, so the probability of being bitten by more than one individual increases in these time bands, especially if the guest approaches the vegetation areas around the places where they breed.

The bite of the black fly

The simulids normally feed on the juices of the vegetables, but the adult females of many species are blood-suckingThat is, they can bite people and other animals, just like mosquitoes. Although unlike these, It is not a sting, but a bite, to suck your blood. This will be a great nutritional contribution for the development and laying of the eggs by the females.

Su mouth appliance is mandibular type, unlike mosquitoes that bite with a stiletto, and therefore perform a painful sting-bite that, in some cases, can bleed. A series of enzymes and histamine mixes with the blood, preventing clotting until the fly ingests it. These bites cause localized tissue damage, and if the amount of flies that are fed is high, their feeding can cause anemia due to blood loss in their victim .

Effects on human health of the black fly bite

Host reaction to fly attacks may include systemic diseases, allergic reactions or even death, presumably mediated by histamine. In humans, this systemic reaction is known as "black fly fever" y it is characterized by:

  • Headaches,
  • fever,
  • nausea,
  • adenitis,
  • dermatitis
  • and allergic asthma.

Some species of these insects are the vectors of Onchocerca volvulus and Mansonella ozzardi, parasites responsible for the so-called river blindness, which affects more than 17 million people in African regions. In birds they are responsible for the transmission of a parasitic protozoan.

As they sting, they inject an anesthetic, a vasodilator, and an anticoagulant that prevent the bite from being noticed instantly. It is later when there is a strong irritation and inflammation of the tissues, and in some cases, health care will be necessary.

  • Adults tend to clump together in cloud or swarm formation
  • The chances of an attack increase if the host approaches the breeding areas
  • The females of many species are blood-sucking (they feed on the blood of people and / or animals)
  • They do not bite, but bite, to suck blood, for this they have a mandibular type apparatus
  • They release a series of enzymes and histamine that mix with the blood to prevent clotting
  • If the attack is by a large group of flies, they can cause anemia due to blood loss in their victim
  • Systemic diseases, allergic reactions, and even death
  • In humans, the systemic reaction is known as "black fly fever"
  • Some species may be vectors of Onchocerca valvulus and Mansonella ozzardi, parasites that cause River Blindness.
  • 17 million people are affected by Onchocerciasis in Africa
  • In their bites they inject an anesthetic, a vasodilator and an anticoagulant to prevent the bite from being noticed instantly
  • Black flies are among the few insects that have killed animals through direct attacks
  • They can kill their victims due to toxic shock
  • Responsible for large-scale livestock deaths
  • Responsible for more than 22.000 deaths along the Danube river
  • It was considered one of the most dangerous species in the world
  • Found throughout Europe
  • We carry out pioneering treatments, in areas of difficult access with our drones
  • Very environmentally friendly application

Effects on fauna of the black fly bite

In 2001, the reintroduction of a migratory population of Grus americana (Trumpeter Crane) into eastern North America was launched. Hatching success, however, was extremely low due to the harassment of black flies (Simuliidae) in hatching birds.

Black flies They are among the few insects that have routinely killed animals by direct attacks, by bleeding or toxic shock (simuliotoxicosis) of the injected salivary components. Around seven species in the world, all developed in large rivers, have been responsible for large-scale livestock deaths.

Although it is now largely a historical phenomenon, the largest killing of domestic animals was caused by Simulium colombaschense (Scopoli), responsible for more than 22,000 deaths along the Danube river in southeastern Europe. This led her to be considered "among the most dangerous species in the world", killing animals on a wide swath beyond the Danube river.

This situation caused the generation of myths among the local population, which was unable to explain the outbreaks. A popular legend said that flies emerged from a cave located in a wall of the river gorge, where a dragon wounded by Saint George had sought refuge and finally died; expelling flies from his head. So powerful was the legend that the Austro-Hungarian government gave the order to close the two caves in the gorge with lead and cement.

The last major outbreak of S . Colombaschense It happened in 1950, killing more than 800 animals.

Due to the large number of species and sub-genera, we can find it in practically all of Europe.

How do we carry out the treatments?

Through the use of our drones, we will carry out a series of totally pioneering treatments. Once again, our potential will be based on the possibility of reaching hard-to-reach areas where it can exist larval breeding and make the treatments in a precise way, allowing treatment of large areas in a very short space of time. On this occasion, through the use of treatments that are consistent with the protection of the rest of the existing fauna and favoring, by mitigating the presence of the plague on the biodiversity of the area.

Once again, as in the rest of our drone treatments, we will carry out a environmentally friendly application.

A Despite being pests that are considered autochthonous to the place, it is advisable to manage it correctly, to avoid massive movements of animal species and to mitigate the terrible effects they produce on the population.

We will be nourished for our operations with drones of last generation technology, which we will use to carry out processes autonomous flight and area analysis to treat. Using systems artificial vision, radiometry or other types of sensors that may be accurate.
