Excretion/defecation patterns in Triatoma infestans populations that are, respectively, susceptible and resistant to deltamethrin
Abstract Pyrethroid resistance has been detected in Triatoma infestans (Klug) (Hemiptera: Reduviidae) specimens from different areas of Argentina and Bolivia. Genes conferring resistance can have a pleiotropic effect with epidemiological and evolutionary consequences. This research studied excretion/defecation patterns in deltamethrin‐resistant T. infestans in order to elucidate its biological performance, adaptive consequences and role in the transmission of Chagas' disease. One deltamethrin‐susceptible strain and two deltamethrin‐resistant strains were used. Fifth‐instar nymphs were fed ad libitum and their defe...

Ecological characterization of a tick community across a landscape gradient exhibiting differential anthropogenic disturbance in the Atlantic Forest ecoregion in Argentina
Abstract An ecological analysis of a tick (Ixodida: Ixodidae) community across a landscape gradient presenting differential anthropogenic disturbance in the Atlantic Forest ecoregion in Argentina was performed. Ticks were collected from vegetation and hosts between September 2014 and August 2016. A total of 12 697 free‐living ticks and 3347 specimens from hosts were collected, including 317 ticks infesting humans. The values obtained show considerable species diversity in the forest environment accompanied by low equitability. The similarity index derived from a comparison of forest and agricultural environments was high...

Temporal distribution of, and effect of anthropic modifications on, phlebotomine populations in the Chaco Bioregion, Argentina
Abstract The Phlebotominae (Diptera: Psychodidae) are insects of medical and veterinary importance, because some species are able to transmit pathogens such as Leishmania spp. In the last 20 years, numerous leishmaniasis outbreaks have been reported in the Chaco Bioregion (Argentina), with an increasing trend of cases associated with periurban transmission. The Chaco Bioregion has two sub‐regions according to their climatic and ecological characteristics: the Dry Chaco and the Humid Chaco. In the present study, sandfly captures were performed in both sub‐regions, at sites with different levels of anthropic modificati...

Co ‐occurrence and seasonal and environmental distributions of the sandflies Lutzomyia longipalpis and Nyssomyia whitmani in the city of Puerto Iguazú, northeastern Argentina
Abstract The aim of this work was to study the distribution of Phlebotominae (Diptera: Psycodidade) abundance in time and space in an area in northeastern Argentina with vector transmission of visceral and tegumentary leishmaniasis. For this, 51 households were selected using a ‘worst scenario’ criterion where one light trap was set during two consecutive nights in peridomiciles in the transitions between the four seasons, and the environment was surveyed simultaneously. The relationships of phlebotomine assemblage structure and the most abundant species with seasonality and environmental variables were evaluated using...

Description of Pintomyia salomoni sp. n., a new phlebotomine species from northwest Argentina
Abstract A new species of phlebotomine sandfly is described and illustrated using male and female specimens collected in the provinces of Jujuy and Tucumán, Argentina. Both male and female morphological characters allow the inclusion of the new species within the Pintomyia genus, Pifanomyia subgenus, serrana series (Diptera: Psychodidae). The species was denominated as Pintomyia salomoni n. sp., and is closely related to Pintomyia (Pifanomyia) torresi and Pintomyia (Piffanomyia) boliviana.

Evaluation of efficacy of impregnated curtains in experimental hen houses as a phlebotomine control tool in northeast Argentina
Abstract The aim of this study was to evaluate the effectiveness of insecticide‐impregnated curtains against the entry of phlebotomine (Diptera: Psychodidae) flies into experimental slatted hen houses in an area endemic for American cutaneous leishmaniasis (ACL). Three treatments in experimental dwellings containing three chickens each were applied using, respectively, an impregnated curtain (IC), a non‐impregnated curtain (NIC) and no curtain (NC). A control site without chickens (WC) was included. The study used permethrin at 0.05 g/m2. During each month for 1 year, each experimental hen house randomly received a...
