Characterization of the Buccula, Rostrum, Stridulatory Sulcus, Scutellum, and External Female Genitalia of (Jurberg, Rocha & Lent, 1998), (Stål, 1859), and (Blanchard, 1843) (Hemiptera, Reduviidae, Triatominae).

In Brazil, (Blanchard, 1843) is the most important species in epidemiological terms in the State of Rio Grande do Sul, due to its wide geographical distribution in this state, followed by (Jurberg, Rocha & Lent, 1998) and (Stål, 1859). Structural analysis of the ventral region of the head (rostrum and buccula), thorax (stridulatorium sulcus and scutellum), and external female genitalia of adults of , , and is described here. Scutellum, head, rostrum, and part of the thorax (prosternum) containing the stridulatory sulcus, in both male and female, and the sixth abdominal segment of the female, containing the external genitalia, were processed for scanning electron microscopy studies as routine.

Biology of Triatoma carcavalloi Jurberg, Rocha & Lent, 1998 under laboratory conditions.

Introduction: Triatoma carcavalloi is a wild species that is found in sympatry with Triatoma rubrovaria and Triatoma circummaculata, which are vectors of Trypanosoma cruzi currently found in rural areas of Rio Grande do Sul, Brazil.

Methods: Fertility was assessed and to determine the incubation period, the eggs were observed until hatching. The first meal was offered to 1st stage nymphs.

Trypanosoma cruzi transmission in a captive primate unit, Rio de Janeiro, Brazil.

A breeding in captivity program of neotropical primates for subsequent reintroduction in nature is in progress at the Primatology Center of Rio de Janeiro (CPRJ). Almost 200 animals of 20 species that include both wild captured animals and specimens born in captivity are maintained in CPRJ. Here, we examined 198 primates of CPRJ for infection with the protozoan parasite Trypanosoma cruzi.
