''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 (0.31 miles to 0.93 miles) 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. The insect was used by Sir Vincent Wigglesworth for the detection of insect hormones. It has been implicated in the transmission of transposons between it and some of its vertebrate hosts, squirrel monkeys and opossums. ''Rhodnius prolixus'' is also known as the kissing bug because it tends to feed on the area around victims' mouths.〔http://neurosci.arizona.edu/kissingbugs/basicfacts 〕 ==As disease vector== 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rhodnius prolixus」の詳細全文を読む スポンサード リンク
