“…The infestation of sand flies in anthropic settings around Barreirinhas and Santo Amaro was most likely caused by deforestation and disturbance of green areas associated with urban expansion, a situation that has been observed previously in towns of southern Brazil [ 20 ]. Ramos et al .…”

BackgroundThe Lençóis Maranhenses National Park, located in Maranhão, Brazil, is a region of exceptional beauty and a popular tourist destination. The adjoining area has suffered from the impact of human activity and, consequently, has experienced outbreaks of leishmaniasis. This study aimed to evaluate the composition, abundance, species richness and seasonal distribution of sand flies in the region and to determine the constancy of the insect population.MethodsThe survey was conducted at three sites located in the municipalities of Barreirinhas and Santo Amaro between September 2012 and August 2013. Sampling was performed monthly using automatic light traps installed 1.5 m above the soil adjacent to 13 randomly selected rural dwellings. At each site, one trap was placed in the peridomicile near to animal enclosures and another (extradomicile) at 500 m from the peridomicile.ResultsA total of 4,474 individual sand flies were collected over the year with the highest abundance recorded during the rainy season (December to June). Nine species were collected: L. whitmani, L. longipalpis, L. lenti, L. sordellii, L. evandroi, L. flaviscutellata, L. wellcomei, L. termitophila and L. intermedia. Although peridomiciliary and extradomiciliary environments presented similar species richness, the Shannon diversity index was significantly lower in the former (H’ = 2.4) compared with the latter (H’ = 4.98). Lutzomyia whitmani and L. longipalpis were the most abundant species and were classified as constant (constancy index, CI = 100 %) along with L. lenti (CI = 58.3), L. evandroi (CI = 58.3) and L. sordellii (CI = 66.7). The remaining four species presented CI values between 25 and 50 % and were considered accessory.ConclusionsThe present results confirm the present of L. whitmani and L. longipalpis in the peridomicile of houses in Lençóis National Park. The abundance of these species could explain, respectively, the endemicity of cutaneous leishmaniasis and sporadic cases of visceral leishmaniasis in the study area. However, in the case of cutaneous leishmaniasis, the presence of other sand fly vectors (in addition to L. whitmani) cannot be neglected. Finally, this study emphasizes the need for a more effective and permanent supervision to control the expansion of these vectors and leishmaniasis outbreaks.

“…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.

“…Association of phlebotomine sandflies with patches of vegetation in urban areas has been documented in other parts of the world with endemic leishmaniasis (Salomón et al 2008, Cerino et al 2009 ). Tapachula has a population of approximately 350 thousand inhabitants [INEGI (inegi.org.mx/)], most of whom are people from other parts of Chiapas, other states within Mexico and most of them are from Central America.…”

Monitoring phlebotomine sandflies in urban areas is key for epidemiological studies in susceptible populations. This paper describes sandfly fauna that were present in an urban area of the municipality of Tapachula, Chiapas, Mexico, and were captured with Shannon and CDC light traps. During February and March of 2014, 1,442 sandflies were captured, specifically Lutzomyia cruciata (Coquillet) (98.8%), Lutzomyia cayennensis cayennensis (Floch and Abonnenc) (0.8%), Lutzomyia chiapanensis (Dampf) (0.3%) and Lutzomyia atulapai (De León) (0.1%). Lu. cruciata was the most abundant and the most frequently trapped species. This is the first record of its remarkable ability to adapt to urban green areas. The three other species trapped represent new records of geographic distribution for the study region. These results indicate the need to establish measures for reducing both human contact with this vector and the risk of possible sites of infection.
