Red imported fire ant

Solenopsis invicta
Tentang namanya: 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

Cara mengenalinya

  • 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

Sengatan

Bisanya keluar lewat sengat.

Apa efek bisanya?

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

Seberapa berbahaya bagi manusia?

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

Kabar baik: dokter punya obat (antibisa) atau pengobatan untuk ini.1

Apa yang dilakukannya saat takut?

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

Jika ia menyengat

  • 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
  • Cuci dan dinginkan sengatannya.
  • Jika orangnya sulit bernapas, wajah atau tenggorokannya bengkak, atau merasa mau pingsan, itu darurat alergi: hubungi nomor darurat.

Selalu hubungi nomor darurat dulu (112, 000, 911). Ini panduan pertolongan pertama umum, bukan nasihat medis. Dasar-dasar pertolongan pertama

Tetap aman

  • Jangan pernah menyentuh, menangkap, atau mengganggu hewan liar, walaupun kecil, dan walaupun tampak tidur atau mati.
  • Beri ia ruang. Jika bertemu, tetap tenang, mundur perlahan, dan biarkan ia pergi.
  • Jika ia menyengatmu: tetap tenang, jangan bergerak, hubungi nomor darurat (112, 000, 911) atau segera ke rumah sakit. Ingat seperti apa rupanya, foto sangat membantu.

Ia tidak mengincarmu. Ia memakai bisanya untuk menangkap makanan atau melindungi diri, dan ia jauh lebih suka bersembunyi. Lebih lanjut tentang tetap aman
