The Rhodnius kissing bug is a blood-feeding insect that feeds on the skin around people's mouths while they sleep. It lives in northern South America and Central America, and it matters because it spreads the parasite that causes Chagas disease.1

Leef in

Northern South America and Central America1

Noord-Amerika, Suid-Amerika

Tuis

Its wild populations are mainly in savanna and foothills, at altitudes of 500 to 1,500 metres, and are closely linked to palm trees. In Central America it lives only in houses and other buildings near people.1

Lengte

2 cm (0,8 in)3

tipiese grootte van 'n volwasse dier

Topspoed

omtrent 0,5 km/h (0,31 mph)

Op land, rowwe skatting

Wat eet dit?

It feeds on the blood of its hosts, which include birds, rodents, marsupials, sloths and reptiles, as well as people. It takes one large blood meal at each larval stage.1

Hoe om dit te herken

Feeds on blood, usually from the area around a sleeping person's mouth1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

It is the main carrier of the parasite that causes Chagas disease in northern South America, and the only carrier in Central America. The parasite is passed in the bug's faeces straight after a blood meal. People can become infected when they scratch the bite and rub the faeces into it, through a blood transfusion, or by eating food contaminated with the bug's faeces.1

As dit byt

Vir ruspe-brandhare: lig hulle af met kleefband en was dan die vel. Moenie vryf nie.
Vir byte: was en koel af. Kry mediese hulp as die persoon sleg voel of maklik bloei.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Its saliva contains lipocalins, which bind the chemical serotonin. This helps stop the host's blood vessels from narrowing while the bug feeds.1

Sir Vincent Wigglesworth used this bug to study insect hormones. He showed that removing the head during a larval stage makes the insect develop into an adult early.1

Specimens from Venezuela escaped from a research laboratory in San Salvador in 1915 and then spread through Central America, probably helped by travellers carrying them.1

Its wild populations have been linked to the transfer of transposons, which are pieces of DNA that move around, between the bug and some of its hosts, such as squirrel monkeys and opossums.1

The insect goes through five larval stages, and each one ends in a moult about 12 to 15 days after a large blood meal.1
