Ekhaya

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

Sidlani?

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

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

Uma siluma

Ezinweleni zezimbungu ezihlabayo: zisuse ngetheyiphu enamathelayo, bese ugeza isikhumba. Ungahlikihli.
Uma kulunyiwe: geza bese upholisa. Thola usizo lwezokwelapha uma umuntu ezizwa engaphilile noma opha kalula.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

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
