Flight and nutritional status of sylvatic Triatoma sordida and Triatoma guasayana [PDF]

Memórias do Instituto Oswaldo Cruz, 2001
Nutritional status relating to flight activity was investigated in natural populations of Triatoma sordida and T. guasayana during the dry season in the Bolivian Chaco. The peak flight activity of both species was unimodal and covered the period 61-180 min after sunset. The weight of insects was used as the indicator of nutritional status. Interspecies

Phylogenetic structure of geographical co‐occurrence among New World Triatominae species, vectors of Chagas disease

Journal of Biogeography, Volume 47, Issue 6, Page 1218-1231, June 2020., 2020
Abstract Aim The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, the validity of TNC for less‐known taxa such as disease vectors is not clear.

Rewiring the Vehicle: <i>Trypanosoma cruzi</i> Parasites Alter the Antennae of Their Triatomine Hosts. [PDF]

Ecol Evol
Parasite Trypanosoma cruzi infects triatomine bugs. Infection induces antennal sensillum change in distribution and number in bugs. Antennal sensillum changes can make the bugs' search for food more efficient. ABSTRACT This study investigates the antennal phenotype of the kissing bug Triatoma pallidipennis (Stål), a primary vector of Chagas disease, by

Feeding and defecation behavior of Triatoma rubida (Uhler, 1894) (Hemiptera: Reduviidae) under laboratory conditions, and its potential role as a vector of chagas disease in Arizona, USA [PDF]

, 2011
Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to humans by blood-sucking triatomine insects. This disease is endemic throughout Mexico and Central and South America, but only a few autochthonous cases have been reported
