  • Rhodnius prolixus is the second most important 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 meters to 1,500 meters (1600 feet to 4,900 feet) above sea level and temperatures of 16 °C to 28 °C (61 °F 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.
  • hodnius prolixus is a major vector of Chagas disease, an illness caused by Trypanosoma cruzi which affects approximately 7 million people worldwide[1][2].
