Red imported fire ant

Solenopsis invicta

O mene: 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

Domov

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

Čo je?

It eats dead mammals, arthropods, insects, seeds and sweet substances such as honeydew from hemipteran insects, with which it has developed relationships. It forages on warm or hot days, though it may stay outside at night.1

Ako ho spoznať

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

Sila jedu

Čo robí jeho jed?

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

Aké nebezpečné je pre ľudí?

Nebezpečenstvo pre ľudí: BolestivéMôže to poriadne bolieť, ale skoro nikdy to nie je vážne.

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

Dobrá správa: lekári na to majú liek (protijed) alebo liečbu.1

Čo robí, keď sa bojí?

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

Ak bodne

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

Ak má postihnutý problémy s dýchaním, opuchnutú tvár alebo hrdlo, alebo sa cíti na odpadnutie, ide o alergickú núdzovú situáciu: zavolaj na tiesňovú linku.

Vždy najprv zavolaj na tiesňovú linku (112, 000, 911). Toto sú všeobecné rady prvej pomoci, nie lekárska rada. Základy prvej pomoci

Buď v bezpečí

Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
Ak ťa bodne: zostaň pokojný, nehýb sa, zavolaj na tiesňovú linku (112, 000, 911) alebo sa rýchlo dostaň do nemocnice. Zapamätaj si, ako vyzeralo, fotka pomôže.

Nejde po tebe. Jed používa na chytanie potravy alebo na obranu a oveľa radšej sa schová. Viac o tom, ako zostať v bezpečí

Fakty

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

Lovec mýtov

Mýtus: The name "fire ant" comes from fire or burning nests.

Pravda: The name comes from the burning sensation caused by its sting.1

Pre znalcov jedov

Vedecký názov: Solenopsis invicta
Skupina: Mravce
Rodina: Formicidae2
Rad: Hymenoptera
Kontinenty: Južná Amerika
Mláďatá: Winged males and queens mate during a nuptial flight in the warm seasons. A colony can be started by a single queen or by a group of queens, which later compete for dominance once the first workers emerge.1
