Synanthropic triatomines in Hidalgo state, Mexico: Spatial-temporal distribution, domestic transmission cycle, and natural infection with Trypanosoma cruzi

Triatoma pallidipennis (Stål, 1872) (Hemiptera: Reduviidae) and its potential for infestation in Tecozautla, Hidalgo state, Mexico

“…In the state of Hidalgo, the presence of four Triatominae species has been reported, all naturally infected with T. cruzi (Salazar-Schettino et al 2010, Antonio-Campos et al 2019). Recently, the presence of a single specimen of T. pallidipennis was reported in the state (Chico-Avelino et al 2022), but it was not collected again until two years later. The presence of T. pallidipennis in Hidalgo state extended the distribution of the species already considered to be the most widely distributed in Mexico.…”

“…Triatoma pallidipennis, also known as Meccus pallidipennis, is distributed in fourteen states, throughout western, eastern, central, and southern Mexico (Salazar-Schettino et al 2010, Martínez-Ibarra et al 2014). A female was collected on October 21, 2019, in Guadalupe, Tecozaulta, Hidalgo state (Chico-Avelino et al 2022). However, and despite the most recent report, there is currently no description of its morphology or data on its behavior.…”

Biological aspects of crosses between populations of Triatoma mexicana (Hemiptera: Reduviidae: Triatominae)

“…1) (Rivas et al 2021, 2022). Triatoma mexicana is an important vector in some areas of San Luis Potosí and Guanajuato and is the most distributed and main vector of T. cruzi in Hidalgo and Querétaro (Villagrán-Herrera et al 2018, Buekens et al 2020, Gámez-Hidalgo 2020, Chico-Avelino et al 2022). According to the most common taxonomic keys (Lent and Wygodzinsky 1979), apparently all specimens of T. mexicana collected in its distribution area belong to this species.…”
