sp. nov. (Hemiptera: Reduviidae) from Mexico, with a Key of Species Recorded in Mexico.

Thirty-four species of Triatominae (Hemiptera, Reduviidae) are recorded in Mexico, Laporte, 1832 the most speciose genus in this country. Here, we describe sp. nov.

The Triatoma phyllosoma species group (Hemiptera: Reduviidae: Triatominae), vectors of Chagas disease: Diagnoses and a key to the species.

The Triatoma phyllosoma species group includes 17 species of kissing bugs, most of them implicated in the transmission of Chagas disease in the Americas. The species of this group are T. bassolsae Alejandre-Aguilar, Nogueda-Torres, Cortz-Jmenez, Jurberg, Galvo Carcavallo, 1999, T.

[Risk of transmission of Chagas disease by intrusion of triatomines and wild mammals in Bucaramanga, Santander, Colombia].

Introduction: Notice of triatomines in dwellings of some neighborhoods in Bucaramanga motivated the realization of this study.Objetive: To evaluate the intrusion of triatomines and mammals, as well as some risk factors in urban dwellings.

Materials And Methods: Triatomines were collected in a neighborhood in Bucaramanga, Santander, on a monthly basis during one year with participation of the community.

[Diversity of Triatominae (Hemiptera: Reduviidae) in Santander, Colombia: Epidemiological implications].

Introduction: Domestic and wild triatomines in the department of Santander have an epidemiological impact, as recently they have been linked to outbreaks of acute Chagas disease. The analysis of their diversity and temporal variation contributes to the understanding of their biology and ecology in one of the most endemic areas of the country.

Objectives: To analyze triatominae diversity in two regions of Santander.

On palms, bugs, and Chagas disease in the Americas.

Palms are ubiquitous across Neotropical landscapes, from pristine forests or savannahs to large cities. Although palms provide useful ecosystem services, they also offer suitable habitat for triatomines and for Trypanosoma cruzi mammalian hosts. Wild triatomines often invade houses by flying from nearby palms, potentially leading to new cases of human Chagas disease.

[Comparison of methods for the capture of triatomines ( Hemiptera: Reduviidae ) in Attalea butyracea palms in the Eastern Plains of Colombia].

Introduction: Studying triatominae in their natural ecotopes has great significance in the epidemiology of Chagas disease. Gathering live insects and the establishment of insectaries allows countless studies. Therefore, effective methods are needed for capturing wild triatomines, especially intrusive species such as Rhodnius prolixus .

[Attalea butyracea palms adjacent to housing as a source of infestation by Rhodnius prolixus (Hemiptera: Reduviidae)].

Introduction: The presence of Rhodnius prolixus in palms on the eastern plains area of Colombia provide a high risk for infection with Trypanosoma cruzi. Intensive surveillance of the palm tree habitat are necessary to confirm the presence of bugs and provide evidence that this habitat is a source of house infestations.

Objective: The infestation by R.

[New trap for the capture of triatomines in wild and peridomestic habitats].

Introduction: Wild triatomines have become increasingly important in the transmission of Chagas disease because of their frequent house entry behavior. Knowledge of their biology is limited, and few tools are available for their collection. These needs led to the design of a new trap for live triatomines.

[Antennal phenotype variation in sylvatic, peridomestic and domestic populations of Triatoma dimidiata (Hemiptera: Reduviidae) from Santander, Colombia].

Introduction: Triatoma dimidiata is one of the widely distributed triatomines in Colombia. The phenotype of the antenna is a characteristic of populations that can differ among habitats and can give information concerning its biology and behavior. This information in turn can be used in the development of new methodological proposals for its control.

Analysis of antenal sensilla patterns of Rhodnius prolixus from Colombia and Venezuela.

Antennal sensilla patterns were used to analyze population variation of domestic Rhodnius prolixus from six departments and states representing three biogeographical regions of Colombia and Venezuela. Discriminant analysis of the patterns of mechanoreceptors and of three types of chemoreceptors on the pedicel and flagellar segments showed clear differentiation between R. prolixus populations east and west of the Andean Cordillera.
