***Rhodnius prolixus*** is the principal triatomine vector of the Chagas parasite due to both its sylvatic and domestic populations in northern South America as well as to its exclusively domestic populations in Central America. It has a wide range of ecotopes, mainly savanna and foothills with an altitude of between 500 and 1 500 metres (1 640 and 4 921 ft) above sea level and temperatures of 16 to 28 °C (61 to 82 °F). Sylvatic *R. prolixus*, as virtually all *Rhodnius* spp. is primarily associated with palm tree habitats and has a wide range of hosts including birds, rodents, marsupials, sloths, and reptiles.

secrete the juvenile hormone which prevents the premature development into an adult.  The removal of the head during any larval stage causes early development into an adult, whereas the implantation of a juvenile head during the fifth larval stage results in a giant sixth stage larva.

The adult secretes compounds into the wound during feeding, including lipocalins. These lipocalins were demonstrated to serve various functions including sequestering amines – especially serotonin – to prevent vasoconstriction (and possibly coagulation) in the host by Andersen et al. 2003.
The male reproductive system of *R. prolixus* contains four accessory glands, three which are responsible for producing the spermathecae and one which is responsible for the movement of spermatozoa from the spermatophore into the female. Once mating occurs, the sperm move through the reproductive system of the female through peristatic waves. The female then stores the sperm until fertilization.

Modelo:Further

Chagas disease is caused by the parasitic protozoan *Trypanosoma cruzi*.
Infection with Chagas disease occurs after *Rhodnius* releases protozoans in its
feces immediately following a blood meal. The parasite enters the victim through
the bite wound after the human host scratches the bite. Infection may also occur via blood
transfusion and ingestion of food contaminated with kissing bug feces.[]
