Ecotopes, natural infection and trophic resources of Triatoma brasiliensis (Hemiptera, Reduviidae, Triatominae).

The synanthropic process of Chagas disease vectors in Brazil, with special attention to Triatoma brasiliensis Neiva, 1911 (Hemiptera, reduviidae, triatominae) population, genetical, ecological, and epidemiological aspects.

Wild habitat and related fauna of Panstrongylus lutzi (Reduviidae, Triatominae).

Although Panstrongylus lutzi (Neiva and Pinto) is currently the fifth most frequent species of Triatominae captured in artificial structures in Brazil, its silvatic habitat remains unknown. A survey of its natural ecotopes was performed in an area of Bahia State. P. lutzi nymphal instars and adults were detected in burrows of Dasypodidae. Silvatic habitat of four other endemic triatomine specie...

Triatoma juazeirensis sp. nov. from the state of Bahia, Northeastern Brazil (Hemiptera: Reduviidae: Triatominae).

Triatoma juazeirensis, a new triatomine species from the state of Bahia, Northeastern Brazil, is described. The new species is found among rocks in sylvatic environment and in the peridomicile. Type specimens were deposited in the Entomological Collection of Oswaldo Cruz Institute-Fiocruz, Museum of Zoology of University of São Paulo, and Florida Museum of Natural History. T. juazeirensis can b...

Influence of light conditions on adult mortality and egg-laying of Triatoma brasiliensis Neiva, 1911 (Hemiptera: Reduviidae: Triatominae).

We compared, for Triatoma brasiliensis, the egg-laying process and the mortality of adults under conditions of almost permanent darkness and with normal laboratory luminosity. Mortality did not differ between groups. The egg-laying per vial and per female was significantly greater in the group of normal luminosity. We consider that it is not recommendable to keep the adults of this species unde...
