Sir Vincent Brian Wigglesworth CBE FRS was a British entomologist who made significant contributions to the field of insect physiology. He established the field in a textbook which was updated in a number of editions.

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 above sea level and temperatures of 16 to 28 °C. 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.
