“…As regards the partial nocturnal rhythm of N. whitmani in the PEMD: it is similar to that observed by Galati et al (1996), presenting peaks between 8:00 pm and 9:00 pm, suggesting that this period is the one which presents the highest risk of infection. In the São Paulo State its most intense activity occurred during the 3 rd hour after dusk (MAYO et al, 1998), whereas in the north of Paraná State, it occurred from 9:00 pm to 10:00 pm (TEODORO et al, 1993) and in the Bandeirantes municipality in the same state, from 8:00 pm to 10:00 pm (MASSAFERA et al, 2005).…”

“…In Corguinho municipality, Mato Grosso do Sul State, the seasonal pattern of L. whitmani, with peaks in the winter (GALATI et al 1996), was similar to that found in the PEMD. The decrease in the number of specimens of L. whitmani captured in the summer and autumn was related to higher atmospheric humidity and the moderate winds when the captures were made, factors already recognized as interfering in the activity of the sandflies.…”

SUMMARYAmerican cutaneous leishmaniasis (ACL) occurs in epidemic outbreaks and in sporadic cases with small annual variation in the Pontal of Paranapanema, SP. There is little research on the sandfly fauna of this region. The last outbreaks were related to the Movement of the Landless Workers (MST) and with the ecological tourism in preserved forest of the Parque Estadual do Morro do Diabo (PEMD). Aim: identification of the sandfly fauna within the PEMD, mainly anthropophilic species already incriminated as vectors of ACL, as well as their seasonality, hourly frequency and data of the behavior. M&M: The captures were undertaken with CDC light and Shannon traps from 6:00 pm to 10:00 pm, monthly from May 2000 to December 2001. The temperature and relative humidity data were registered at hourly intervals. Results: The captured species were: Brumptomyia brumpti, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri and Pintomyia pessoai. The P. pessoai predominated (34.39%) and N. neivai was less found (0.74%), only being captured in CDC traps. Shannon trap captured more sandflies (63.01%) than the CDC traps (36.99%). Despite the environmental degradation anthropophilic species, indicates favorable bioecological conditions for persistence of vectors and potential transmission of leishmaniasis.

“…Analysis of the results showed that, similar to other areas of ACL occurrence in the State of Mato Grosso do Sul 4,40,41 , disease transmission is associated with wild vector patterns and with human exposure to vectors in their natural habitat.…”

“…A rich variety of sandfly species in different ecotopes has been identified in several ecological studies conducted in this state. These studies have indicated new species or have reinforced the role that some of them play in the transmission of leishmaniasis to the population of different municipalities, contributing to current understanding of the epidemiology of these diseases in the state [1][2][3][4][5][6] .…”

INTRODUCTION: The work was conducted to study phlebotomine fauna (Diptera: Psychodidae) and aspects of American cutaneous leishmaniasis transmission in a forested area where Leishmania (Leishmania) amazonensis occurs, situated in the municipality of Bela Vista, State of Mato Grosso do Sul, Brazil. METHODS: The captures were conducted with modified Disney traps, using hamster (Mesocricetus auratus) as bait, from May 2004 to January 2006. RESULTS: Ten species of phlebotomine sandflies were captured: Brumptomyia avellari, Brumptomyia brumpti, Bichromomyia flaviscutellata, Evandromyia bourrouli, Evandromyia lenti, Lutzomyia longipalpis, Psathyromyia campograndensis, Psathyromyia punctigeniculata, Psathyromyia shannoni and Sciopemyia sordellii. The two predominant species were Ev bourrouli (57.3%) and Bi flaviscutellata (41.4%), present at all sampling sites. Two of the 36 hamsters used as bait presented natural infection with Leishmania. The parasite was identified as Leishmania (Leishmania) amazonensis. CONCLUSIONS: Analysis of the results revealed the efficiency of Disney traps for capturing Bichromomyia flaviscutellata and the simultaneous presence of both vector and the Leishmania species transmitted by the same can be considered a predictive factor of the occurrence of leishmaniasis outbreaks for the human population that occupies the location.

SUMMARYThe main purpose of this study was to investigate natural infection by Leishmania in phlebotomine females in a visceralleishmaniasis focus in Antonio João county in Mato Grosso do Sul State, Brazil. Between June and October 2003, the digestive tracts of 81 females captured in Aldeia Campestre, Aldeia Marangatu and Povoado Campestre were dissected. The females were separated by species, location, area and date of capture into 13 groups and kept in ethanol 70%. To identify the Leishmania species using the PCR technique, amplifications of the ribosomal-DNA (rDNA) and mini-exon genes were analyzed. Of the 81 specimens, 77 (95%) were Lutzomyia longipalpis, making this the most common species; only one specimen of each of the species Brumptomyia avellari, Evandromyia cortelezzii, Evandromyia lenti and Nyssomyia whitmani was found. Trypanosomatids were identified in eight of the nine groups of Lutzomyia longipalpis (10.39%) one group from Aldeia Campestre, one from Aldeia Marangatu and six from Povoado Campestre; of the eight groups, one from Aldeia Marangatu and another, with promastigotes forms also confirmed by dissection (1.23%) from Povoado Campestre, were identified by PCR as Leishmania chagasi (2.6%). The other groups gave negative results. These findings indicate that there is a high risk of leishmaniasis transmission in this area.
