ABSTRACT This study investigates the antennal phenotype of kissing bug Triatoma pallidipennis (Stål), a primary vector Chagas disease, by comparing Trypanosoma cruzi ‐infected and noninfected individuals. We examined antennae infected N5 nymphs, as well adult females males, focusing on four types sensilla (bristles, basiconic, thin‐walled trichoid, thick‐walled trichoid) across three antenna segments (pedicel, proximal flagellum, distal flagellum). found differences in abundance segments,...
In this study, we evaluated the responses of Triatoma dimidiata Latreille (Hemiptera: Reduviidae) to volatiles emitted by conspecific females, males, mating pairs and metasternal gland (MG) extracts with a Y‐tube olfactometer. The volatile compounds released MGs T. were identified using solid‐phase microextraction coupled gas chromatography‐mass spectrometry (GC‐MS). Females not attracted males or MG extracts; however, they preferred clean air their own those from pairs. Males pairs, in...
Triatoma dimidiata (Latreille) is a key vector complex of Trypanosoma cruzi, etiologic agent Chagas disease, as it spans North, Central, and South America. Although morphological genetic studies clearly indicate existence at least five clades within the species, there has been no robust or systematic revision, appropriate nomenclature change for species complex. Three (haplogroups) are distributed in Mexico, recent evidence attests to dispersal across previously "presumed" monotypic...
Triatoma dimidiata is the vector of Trypanosoma cruzi in Yucatan Peninsula (YP). Earlier studies have shown that domestic and peri-domestic populations originated from sylvan stock effectiveness insecticide-spraying was affected by re-infestations houses T. population. In addition, YP most previously published reports focused on very little known about nocturnal behavior populations. The main aim our study to determine nightly activity patterns adult a selected location YP. Secondly, we...
The Triatoma phyllosoma complex of Trypanosoma cruzi vectors (Triatominae: Reduviidae) is distributed in both Neotropical and Nearctic bioregions Mexico. Volatile organic compounds emitted by disturbed longipennis, pallidipennis phyllosoma, from their Brindley’s metasternal glands, were identified using solid-phase microextraction coupled with gas chromatography-mass spectrometry. Disturbed bugs the glands T. released or had significantly fewer than longipennis pallidipennis. Isobutyric acid...
Triatoma dimidiata is a vector of the protozoan parasite Trypanosoma cruzi, etiologic agent Chagas disease. Phenotypic plasticity allows an organism to adjust its phenotype in response stimuli or environmental conditions. Understanding effect T. cruzi on phenotypic vectors, known as triatomines, has attracted great interest because implications parasite-triatomine interactions eco-epidemiology and transmission We investigated if infection with may be associated change antennal sylvatic,...
The Mexican territory of the Yucatan Peninsula has a tropical climate and harbors wide variety domestic, synanthropic, wild animals, as well disease vectors. To determine distribution recorded zoonotic diseases in Peninsula, scientific publications referring to these animals containing geographic coordinates occurrence, were studied. epidemiological bulletins national government also consulted obtain information on reported humans territory. pathogens, including Trypanosoma cruzi, Leptospira...

Abstract Background: Triatoma dimidiata is a vector of the protozoan parasite Trypanosoma cruzi , etiologic agent Chagas disease. Phenotypic plasticity allows an organism to adjust its phenotype in response stimuli or environmental conditions. Understanding effect T. on phenotypic vectors, known as triatomines, has attracted great interest because implications parasite-triatomine interactions eco-epidemiology and transmission parasite. We investigated whether infection with can change...
Chagas disease is caused by Trypanosoma cruzi, whose genetic structure divided into six discrete typing units (DTUs) known as TcI-TcVI. In the Yucatan Peninsula, Mexico, information regarding DTUs circulating in wild mammals scarce, while this important knowledge for our understanding of T. cruzi transmission dynamics. current study, we sampled a sylvatic site Peninsula and assessed their infection with PCR. Then, infected mammals, amplified sequenced nuclear mitochondrial markers DTU...
