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

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

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

Ikaluma

  • Pa ubweya wa mbozi zolasa: uchotse ndi tepi yomata, kenako sambitsa khungu. Usasisite.
  • Polumidwa: sambitsa ndi kuziziritsa. Peza thandizo la dokotala ngati munthuyo sakumva bwino kapena akutuluka magazi mosavuta.

Nthawi zonse yamba wayimbira nambala yadzidzidzi (112, 000, 911). Awa ndi malangizo wamba a chithandizo choyamba, osati malangizo a dokotala. Zoyambira za chithandizo choyamba

Khala wotetezeka

  • Usakhudze, kugwira kapena kuseweretsa nyama yakuthengo, ngakhale yaing'ono, ndipo ngakhale ikuoneka ngati yagona kapena yafa.
  • Ipatse malo. Ukakumana nayo, khala chete, bwerera m'mbuyo pang'onopang'ono ndipo uilole ipite njira yake.
  • Ikakuluma: khala chete, usasunthe, imbira nambala yadzidzidzi (112, 000, 911) kapena pita kuchipatala mwachangu. Kumbukira m'mene inkaonekera, chithunzi chimathandiza.

Sikufuna kukuvulaza. Imagwiritsa ntchito ululu wake kugwira chakudya kapena kudziteteza, ndipo imakonda kwambiri kubisala. Zambiri za kukhala wotetezeka

Mfundo

1

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

2

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

3

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

4

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

5

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
