How far do mosquitoes travel

How far do mosquitoes travel, Most mosquitoes, however, have the ability to fly 1-3 miles. Some of the larger mosquitoes in the Midwestern United States can be found 7 miles or more from their breeding sites.

How far do mosquitoes travel? How many diseases spread per day and for how long? That’s why we have to know about mosquitoes travel distance. Its help to control disease like dengue fever.

A few types of mosquitoes bring infinite suffering to humanity. Ecologist Michael Jeffries asks: Shouldn’t we free ourselves from this agony, finally? If they travel more distance, viruses like Zika will be spread to another continental.

Mosquitoes, also known as mosquitoes: blood-sucking, deadly creatures of the dawn, more terrifying than those vampire demons that used to nest in our nightmares. Mosquitoes don’t appear to be as glamorous as Dracula, but they are, unfortunately, very real. And with the sudden appearance and explosive spread of the Zika virus in Latin America, our old hereditary enemies are now showing their monstrous side again.

About 3,500 mosquito species live on Earth – a modest number for an insect family. And among them, it’s just a small bunch of species that are attacking human health. However, this unit is mobile, powerful, ready for expansion and perfectly adapted – it includes the Asian tiger mosquito, which among other things spreads dengue fever and the Chikungunya virus, the malaria mosquitoes of the genus Anopheles or the yellow fever mosquito Aedes aegypti.

The health effects of peoples are apocalyptic. Because of the mosquitos, mankind is still afflicted with plagues of biblical proportions: up to 500 million new infections with malaria every year, plus 100 million with dengue fever. And as if that weren’t enough of suffering, mosquitoes are also responsible for the spread of diseases such as West Nile fever. Or for the Zika infection.

Mosquitoes cause a greater loss of life than any other being on the planet (excluding ourselves, of course). Which raises the question: What are they good for? And: If we could erase them from the face of the earth – should we do that?

The mosquito defenders plead:

Mosquitoes are an important link in the food chain. Especially in the arctic tundra, where hatching mosquitoes appear in huge flocks for a few summer weeks, they offer migratory birds a rich range of feed. In a contribution to the magazine “Nature”, author Janet Fang draws attention to another positive effect: the attack of the swarms of mosquitoes redirects the migration of the reindeer, allows the herds to avoid the pests – thus protecting the grasslands from overgrazing and trampling. Good. In the Arctic, mosquitoes would be missing. But otherwise? Janet Fang’s survey of insect ecologists found that the collateral damage caused by extermination would remain manageable.

The survival of very few other animal species is directly linked to that of the mosquitos. Most mosquito eaters would easily switch to other insects. Bats, for example, prefer moths anyway. Except for one species: Vespadelus vulternus, an Australian species – it actually lives in close dependence on a certain type of mosquito.

But that’s probably the best case that the mosquito defenders can lead into the field. And the mosquito larvae? Yes, admittedly: They are an important link in some freshwater food chains. Specialists such as the Kobold kärpfling (“mosquito fish”) live from them. And in the small waters that form in the deepening of living plants under the canopy of the tropical rainforest, the mosquito larvae also play an important role; for example for the survival of certain poison dart frogs.

The mosquito lawyers have also established a second line of defense. It is based on the concept of ecosystem services and points to the role of mosquitoes in pollinating flowering plants (most mosquitoes feed on nectar, only the females need a protein-rich blood meal to produce eggs). And the larvae of the mosquitoes purify the water in which they live because they feed on organic waste.

Females need a protein-rich blood meal to produce eggs. And the larvae of the mosquitoes purify the water in which they live because they feed on organic waste.

But these arguments do not stand out. The mosquitoes do not hold a monopoly on pollination. They only play a minor role; one that (unlike that of the bee) could easily be deleted and occupied differently. And the larvae? They are also not indispensable as a filter in water. Both niches did not remain empty for long after the mosquitoes died out, other organisms would move up quickly, and the ecological wound would heal quickly.

The verdict has been pronounced. Only: how to enforce it?

The mosquito itself, we all know it, is a fragile being. However, clapping an individual against the wall is one thing; whole ways to destroy something completely different. A tried and tested strategy: to destroy their breeding areas. In the 19th century, Europe became unplanned and virtually incidental to malaria because more and more marshes were converted into arable land or developed industrially. Today, however, we consider wetlands to be the focal points of biodiversity, the destruction of which is self-prohibiting. In addition: some of the worst disease carriers among the mosquitoes do not need natural waters, they also reproduce very successfully in the puddles and ponds that arise as waste biotopes of our urban life.

Local populations can be efficiently cleared out with pesticides. DDT has been used for a long time, quite successfully. But it has been proven that the reckless use of DDT not only damages the mosquitoes, but also numerous other animal species – and ultimately humans because the poison accumulates in our bodies.

This is how biological control methods have been established. Above all, the aforementioned goblin pitcher, which eagerly eats mosquito larvae, is artificially settled in many places. Dragonfly larvae also clean up vigorously – but only among regionally limited mosquito larval populations.

How far do mosquitoes travel

How far do mosquitoes travel..? It depends on the species. Flight capabilities are differents on different species. For example, most mosquito species can fly up to 1-3 miles while other large pool breeders in the Midwest have been known to fly up to 7 miles from their breeding areas. The mosquito species that have been known to fly the furthest is the salt marsh breeders. But they can fly up to 100 miles in certain circumstances, although traveling 20-40 miles is much more common for this species when blood hosts are few and far between. The Asian Tiger Mosquito has a limited flight range of up to 300 feet. The distance a mosquito is in a position to travel also depends on wind updrafts as they will be carried great distances on a robust wind current.

Doubts remain

New methods are also being tested. Researchers change the genetic makeup of captive mosquito males so that they produce offspring that are not able to survive. If such males are released in large numbers and mate, the entire population collapses.

All of these methods work. But only within limits. For at least 40 million years, mosquitoes have been training to survive in an environment hostile to them. You can make up for terrible losses in no time if only a few populations get away unscathed.

As far as I can see, there is no good reason to defend mosquitoes against extermination plans. Their annihilation would take a curse from humanity. But for this fight, we would have to continue to upgrade, perhaps with new weapons from the arsenal of genetic engineering.

But doubts remain. Wouldn’t the pathogens look for other carriers, such as fleas or mites? Above all: I personally don’t like the idea of ​​playing God and exterminating species at all. It is a bitter irony that we humans threaten the existence of many species – only, not those that troubles us so much.
