The Paulista wasp is a social wasp that lives in colonies of thousands of wasps. It is found in Brazil, Paraguay and Argentina. Scientists are studying its venom because some of its peptides (small protein-like molecules) may one day help treat cancer and epilepsy.1

Ubumara bwayo bukora iki?

The venom contains several peptides. These cause pain, swelling (oedema) and haemolysis, which means they break down red blood cells. They also trigger an inflammatory response, which causes physical discomfort.1

Niba itera urubori

Kuramo urubori rw'uruyuki uruharura, kandi ukonjeshe aho rwateye.
Niba umuntu ahumeka bimugoye, akabyimba mu maso cyangwa mu muhogo, cyangwa akumva agiye guta ubwenge, ni ikibazo cyihutirwa cya aleriji: hamagara nimero y'ubutabazi kandi ukoreshe urushinge rwe rwa adrenaline (adrenaline pen) niba arufite.

Ibintu by'ukuri

A peptide in the venom, called Polybia-MP1, kills cancer cells while leaving healthy cells intact, according to research so far. Further studies are needed to confirm it is safe as a chemotherapy drug.1

The venom contains mastoparan, which has been shown to inhibit the parasite Trypanosoma cruzi, the cause of Chagas disease.1

Workers cool the nest by fanning their wings and spreading water on the combs, so the water evaporates and lowers the temperature.1

Colonies can contain from 10 to 94 queens, because young queens are constantly recruited.1

A colony can hold about 4,500 wasps during its early stage, and up to 13,000 wasps while males are being produced.1
