Lifecycle of Triatoma dimidiata and Rhodnius prolixus, Vectors Transmitting American Trypanosomiasis (Chagas Disease) in Central America

This photograph shows the lifecycle of two of the main vectors of American Trypanosomiasis (Chagas Disease) in Central America, T. dimidiata and R. prolixus (chinches), insects that hide in the walls and thatched roofs of humble dwellings and nearby structures and transmit the parasite Trypanosoma cruzi.
