Compounds able to attract and/or arrest some or all of the stadiums of T. infestans could be used in odor-baited traps to improve currently available monitoring and control strategies. For a better understanding of transmission risk, the geographic distribution of Brazilian triatomines was analyzed.

They are polymorphic in appearance.

PDF | Chagas disease or American trypanosomiasis affects six to seven million people worldwide, mostly in Latin America. Although Brazil was declared free from Chagas disease transmission by the domestic vector Triatoma infestans, human acute cases are still being registered based on transmission by native triatomine species.

Chagas vector Geographical distribution Environmental niche model Climatic variables Triatoma infestans Wild ABSTRACT Background: For several years, the wild populations of Triatoma infestans, main vector of Trypanosoma cruzi causing Chagas disease, have been considered or suspected of being a source of reinfestation of villages. 67.

Triatomine, Triatoma infestans, attractant, pheromone, Chagas disease The hematophagous bug Triatoma infestans (Klug) is the major vector of Chagas disease in South America ( Zerba 1989 ). Key characteristics: Three subspecies (protracta, navajoensis, woodi) have been reported from the U.S. Triatoma infestans is the principal vector of Trypanosoma cruzi, parasite responsible of Chagas's Disease transmission in Argentina. T. protracta woodi is featured in the images here. Triatominae insects are vectors of the parasite Trypanosoma cruzi, the etiological agent of Chagas disease affecting millions of people in Latin America. Triatoma infestans is the main vector of Chagas’ disease in South America between latitudes 10°S and 46°S.

Pyrethroids have become common pesticides for the control of T. infestans but increasing resistance encourages the search of new alternatives and the use of natural products for biological control arises as a new strategy.
