Red imported fire ant

Solenopsis invicta

O imenu: Its species name, invicta, is Latin for "invincible" or "unconquered". It is called the fire ant because its sting causes a burning sensation.1

The red imported fire ant is an ant that comes from South America. It has spread to Australia, New Zealand, parts of Asia, the Caribbean, Europe and the United States, where it is seen as a serious pest. Its sting burns, and in some people it causes a dangerous allergic reaction.1

Početna

It lives in a wide variety of places, including rainforests, deserts, grasslands and disturbed land. It is dominant in altered areas and thrives in urban areas, where it nests alongside roads, buildings and in electrical equipment. Colonies build large soil mounds that have no visible entrances.1

Kako ga prepoznati

Workers are red and somewhat yellowish, with a brown or black rear section (gaster).1
Males are completely black.1
Workers come in different shapes and sizes.1
Colonies form large soil mounds with no visible entrances, because foraging tunnels lead to places far from the nest.1

Otrovna snaga

Ubodi

Otrov izlazi kroz žalac.

Što radi njegov otrov kad ugrize ili ubode?

About 95% of its venom is made of water-insoluble piperidine alkaloids called solenopsins, and the rest is a mixture of toxic proteins that can be especially strong in sensitive people. Most stings cause intense burning and swelling, followed by sterile pustules (small fluid-filled bumps) that can last several days. In some people, a severe allergic reaction called anaphylaxis can occur, with dizziness, chest pain, nausea, severe sweating, low blood pressure, shortness of breath and slurred speech.1

More than 14 million people are stung by these ants each year in the United States, and many are expected to develop allergies to the venom. Between 0.6% and 6.0% of people may suffer anaphylaxis, which can be fatal if left untreated. More than 80 deaths have been recorded from attacks by this ant.1

Dobre vijesti: liječnici za ovo imaju lijek (protuotrov) ili liječenje.1

Što radi kad se uplaši?

It uses its venom and chemical signals (pheromones) to defend itself and its nest.1

Ako ubode

People who only have pain and pustules need no medical attention. People who develop anaphylaxis need emergency treatment with adrenaline. Whole body extract immunotherapy is used to treat people who are allergic and is regarded as highly effective.1

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ubode: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Činjenice

When water levels rise, these ants build rafts to float on.1

A single mature colony can contain between 500,000 and 2,000,000 individuals.1

Over 1,800 scientific papers have been published using its name, and it is one of the most studied insects on the planet, rivalling the western honey bee.1

Workers dispose of scraps and dead ants on refuse piles outside the nest, a behaviour called necrophoric behaviour.1

Workers can live for several months, while queens can live for years.1
