“…Species richness and Phlebotominae occurrence were higher in the rural area (Taquaruçu) than in downtown Palmas. Parallel findings were also reported by Cruz et al (2013) in Bandeirantes, state of Paraná. Meanwhile, Vilela et al (2011) also observed high species diversity in rural environments, but the abundance of sand flies was higher in urban environments.…”

“…Meanwhile, Vilela et al (2011) also observed high species diversity in rural environments, but the abundance of sand flies was higher in urban environments. These results may be due to the presence of forests close to households and animal housing structures, as well as to the presence accumulated organic matter, all of which provides conditions that are conducive to the establishment of a Phlebotomine reproductive cycle ( Quinnell & Dye 1994 , Cruz et al 2013) .…”

BACKGROUND Knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence.OBJECTIVE To analyse the occurrence of Phlebotominae in gallery forests and household units (HUs) in the city of Palmas and to determine the rate of natural infection by trypanosomatids.METHODS Gallery forests and adjacent household areas were sampled on July (dry season) and November (rainy season) in 2014. The total sampling effort was 960 HP light traps and eight Shannon traps. Trypanosomatids were detected in Phlebotominae females through the amplification of the SSU rDNA region, and the positive samples were used in ITS1-PCR. Trypanosomatid species were identified using sequencing.FINDINGS A total of 1,527 sand flies representing 30 species were captured in which 949 (28 spp.) and 578 (22 spp.) were registered in July and November, respectively. In July, more specimens were captured in the gallery forests than in the HUs, and Nyssomyia whitmani was particularly frequent. In November, most of the specimens were found in the HUs, and again, Ny. whitmani was the predominant species. Lutzomyia longipalpis was commonly found in domestic areas, while Bichromomyia flaviscutellata was most frequent in gallery forests. Molecular analysis of 154 pools of females (752 specimens) identified Leishmania amazonensis, L. infantum, and Crithidia fasciculata in Ny. whitmani, as well as L. amazonensis in Lu. longipalpis, Trypanosoma sp. and L. amazonensis in Pintomyia christenseni, and L. amazonensis in both Psathyromyia hermanlenti and Evandromyia walkeri.MAIN CONCLUSIONS These results show the importance of gallery forests in maintaining Phlebotominae populations in the dry month, as well as their frequent occurrence in household units in the rainy month. This is the first study to identify Leishmania, Trypanosoma, and Crithidia species in Phlebotominae collected in Palmas, Tocantins, Brazil.

“…In other words, the presence of animal species different from rats was a protection factor against leishmaniosis in rats (OR= 0.01273 to 0.8341). A study on Nyssomyia neivai species broadly found in Paraná State (MEMBRIVE et al, 2004;DIAS-SVERSUTTI et al, 2007;SILVA et al, 2008;CERINO et al, 2009;CRUZ et al, 2013;MELO et al, 2013), performed in Ribeira Valley São Paulo State, examined 988 engorged females, and no rat blood was detected in the phlebotomines (MARASSÁ et al, 2013). According to Dias-Sversutti et al (2007), N. neivai and N. whitmani are opportunists and probably adjust their feeding habits based on the availability of hosts.…”

“…A recent study (CARVALHO et al, 2014) using ecological niche modeling predicts southward expansion of L. flaviscutellata in South America because of climate change. Several studies have investigated phlebotomine fauna in Paraná State (GOMES & GALATI, 1977;TEODORO et al, 1993;TEODORO et al, 1999;OLIVEIRA et al, 2000;DIAS-SVERSUTTI et al, 2007;SILVA et al, 2008;CERINO et al, 2009;REIS et al, 2011;CRUZ et al, 2012;SANTOS et al, 2012;MEMBRIVE et al, 2012;CRUZ et al, 2013;MELO et al, 2013); none reported L. (L.) amazonensis vectors. Taking into account two autochthonous cases (one human and one canine) of leishmaniasis by L. (L.) amazonensis in North Paraná, more studies about phlebotomine fauna must be made in this region, now using Disney traps with rodents as baits (DORVAL et al, 2007), because L. flaviscutellata is strongly attracted to rodents (LAINSON & SHAW, 1968;SHAW & LAINSON, 1972;CARVALHO et al, 2014).…”

Leishmania in synanthropic rodents (Rattus rattus):new evidence for the urbanization of Leishmania (Leishmania) amazonensis AbstractThis study aimed to detect parasites from Leishmania genus, to determine the prevalence of anti-Leishmania spp. antibodies, to identify circulating species of the parasite, and to determine epidemiological variables associated with infection in rats caught in urban area of Londrina, Paraná, Brazil. Animal capture was carried out from May to December 2006, serological and molecular methods were performed. DNA was extracted from total blood, and nested-PCR, targeting SSu rRNA from Leishmania genus, was performed in triplicate. The positive samples were sequenced twice by Sanger method to species determination. In total, 181 rodents were captured, all were identified as Rattus rattus and none showed clinical alterations. Forty-one of the 176 (23.3%) animals were positive for Leishmania by ELISA and 6/181 (3.3%) were positive by IFAT. Nine of 127 tested animals (7.1%) were positive by PCR; seven were identified as L.
