INTRODUCTION: A study on the phlebotomine sandfly fauna was carried out in an endemic area for American tegumentary leishmaniasis in the municipality of Governador Valadares, in the State of Minas Gerais, Brazil. METHODS: Captures were undertaken using HP light traps in four districts, on three nights per month, for one year (from January to December 2008). Correlations between climatic factors (temperature, relative air humidity and rainfall) and the numbers of sandflies collected was observed. RESULTS: 5,413 phlebotomine specimens were caught and were identified as belonging to 12 species. Of these specimens, 2,851 (52%) were females and 2,562 (48%) were males. CONCLUSIONS: Lutzomyia intermedia predominated (29.9% of the species caught), thus suggesting that they were responsible for transmission of American tegumentary leishmaniasis, together with L. whitmani, which was also found in the area (4.3%). The presence of L. longipalpis (11.9%), the main vector for visceral leishmaniasis in Brazil, is an important finding, which makes rigorous entomological surveillance of the area necessary.

SUMMARY This study reports the fauna and frequency of sandflies in domestic animal shelters, residences and other ecotopes in rural areas of the municipality of Bandeirantes, Paraná State. Sandflies were collected twice in eight rural villages by using Falcon traps from 8pm to 6am in 2008. In these localities 4,790 sandflies were collected, which were represented by ten sandfly species, prevailing of Nyssomyia neivai and Nyssomyia whitmani species. It was observed that animal shelters are the domestic ecotopes where there is the greatest frequency of these insects. The localities where the collections were made had the environmental characteristics that allow the persistence of transmission of parasites from the American tegumentary leishmaniasis. Although the fauna and the behavior of sandflies species are similar in different localities, the method of controlling these insects should be adjusted to the environmental characteristics of each one of the most diverse endemic areas of American tegumentary leishmaniasis in the municipalities of Paraná State.

American tegumentary leishmaniasis is endemic to the Espírito Santo State, Brazil, where it is widely distributed. The composition of the phlebotomine sand fly fauna in an American tegumentary leishmaniasis focus was determined by monthly sampling, using Shannon light traps in an Atlantic Forest reserve and adjacent habitat that had been modified by human activity. Seasonal fluctuations in numbers of the most abundant species were also monitored from June 2004 to May 2006. Of the 6,176 specimens collected, 47.4% were captured in the forest and 52.6% in the disturbed habitat. Although Lutzomyia davisi (60.8%) predominated in specimens from the forest, those captured near human dwellings consisted almost entirely of Lu. choti (72%) and Lu. intermedia (24.3%). All three species occurred throughout the year. Based on our findings, Lu. intermedia probably acts as the principal domestic Leishmania vector in the study area.

INTRODUCTION: Governador Valadares is an endemic area of American tegumentary leishmaniasis (ATL). The detection rate was 15.36 per 100,000 habitants from 2001 to 2006 (Miranda, 2008). This study aimed to analyze the effects of age on the frequency of adverse reactions caused by antimony in the treatment of ATL in the City of Governador Valadares, State of Minas Gerais, Brazil, during 2009. METHODS: Data were collected from the forms of the Information System for Notifiable Diseases, and from charts, questionnaires, and home visits to patients. RESULTS: The study included 40 patients, 26 (65%) of whom were males. Individuals over the age of 50 had a 66% higher rate of adverse effects than subjects who were 50 years old or less (CI 95%, 1.14-2.41). The average age of individuals who reported some type of adverse effect was 44.11 years (SD = 20.14), while the average age of the group that did not report any adverse effect was of 25.46 years (SD = 18.37; p < 0.01). Clinical healing was 67.5%, and 10% of patients discontinued the treatment. CONCLUSIONS: In the treatment of ATL, the age of patients should be considered, because most adverse reactions occur in individuals over 50 years of age. For this reason, the drug should be used with restriction in these cases.

INTRODUCTION: In the last decades, a considerable geographic expansion of the leishmaniases in all regions of Brazil has been observed. The present study was carried out to identify the composition of the phlebotomine sandfly fauna and verify the seasonal variation of the main species after environmental changes occurred in São Vicente Férrer Municipality, State of Pernambuco, Brazil. METHODS: Captures were carried out during four consecutive nights of each month using Centers for Disease Control and Prevention light traps from September 2009 to September 2010. The correlation between the number of phlebotomine sandflies captured and climatic factors (temperature and rainfall) was evaluated. RESULTS: A total of 13,872 specimens belonging to 20 species were captured, of which, 6,247 (45%) were females, and 7,625 (55%) were males. Lutzomyia migonei was the most abundant species with 9,964 (71.8%) specimens, being predominant in the intradomicile and peridomicile areas with 108 (86.4%) and 9,746 (97%), respectively. In the forest remnants, Lutzomyia complexa 2,395 (65%) and Lutzomyia sordellii 770 (20.8%) predominated. The correlation analysis between the total number of sandflies captured and climatic factors did not show a significant influence on population density. CONCLUSIONS: The high abundance of Lutzomyia migonei and Lutzomyia complexa indicates the possibility of new cases of cutaneous leishmaniasis (CL).

A one year-long study (March 1979-March 1980) was carried out at San Esteban, an endemic focus of cutaneous leishmaniasis in Northern Venezuela, with the aim of observing the seasonal fluctuation of the local phlebotomine sandflies species. The influence of climatic factors (temperature, relative humidity and rainfall) on population dynamics was analyzed in three collecting sites - a house, a peridomestic area and a sylvatic region. Among anthropophilic species, L. panamensis behaved as a wetseason species, the mean minimum relative humidity being the critical factor influencing the total number of individuals. When the population density of this fly decreased, it was successfully replaced by L. ovallesi, a dry-season species. On the other hand, seasonal variations of L. gomezi were more strongly affected by the temperature.

American Tegumentary Leishmaniasis is endemic in the province of Tucumán since 1916 where the first Argentinian case of leishmaniasis was reported. An epidemic outbreak took place in the province during 1986-1988, after that the number of cases increased gradually again between 1991-1996. Since October of 1999 sand flies captures were performed at different places associated with current and past transmission or sites identified as risky ones. The collections were carried out with CDC mini light trap and modified Shannon trap. In this study 2338 Phlebotominae were captured being prevalent Lutzomyia neivai (Lu intermedia complex) (97.7%), followed by Lu. migonei. We report Lu. shannoni for the first time in the province. Phlebotominae was abundant in the warm and humid months and showed a peak before the summer rains. Lutzomyia neivai showed a pattern (peridomestic prevalence, anthropophilia, abundance in secondary forest) consistent with other outbreak studies. Thus, the results reinforce this species incrimination as vector of leishmaniasis in the area. Domestic animals close to houses increase its abundance, and so the probable associated risk of human-Phlebotominae contact. Further studies should be done to understand the role of each Phlebotominae species in the transmission of leishmaniasis in Tucumán in order to design entomological surveillance strategies.

Between April 2003 and May 2009 phlebotomine sandflies were collected in Parque do Sabiá complex, Uberlândia municipality, Minas Gerais State, Brazil, using CDC and Shannon traps. The objective was to associate the sandfly species captured to the risk of the transmission of leishmaniasis in the municipality. The 126 captured specimens belonging to six species of phlebotomine, among which Lutzomyia (Psychodopygus) davisi (Root, 1934) predominated with 113 specimens (89.7%). The remaining captured species were Lutzomyia (Pintomyia) mamedei Oliveira, Afonso, Dias & Brazil, 1994 - five specimens (3.9%); Lutzomyia (Nyssomyia) flaviscutellata (Mangabeira, 1942) - four specimens (3.2%); Lutzomyia lenti (Mangabeira, 1938) - two specimens (1.6%); Brumptomyia avellari (Costa Lima, 1932) - one specimen (0.8%); and Lutzomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1939) - one specimen (0.8%). The collection of species that may be involved in the transmission of Leishmania reveals the need for continuous entomological surveillance.
