| [phlebotomine sand flies in the state of tocantins, brazil (diptera: psychodidae)]. | between 1997-1998, the authors carried out sporadic collection of sand flies in the municipalities of paraíso de tocantins, monte do carmo, porto nacional and monte santo all in the tocantins state of northern brazil. human bait was used in monte santo and a battery operated light trap in other municipalities. the ecotypes chosen for the traps were in the peridomiciles, inside the houses, in the forest and the orchard. we identified 2,677 sand flies, belonging to 32 species. the most abundant sp ... | 2001 | 11562724 |
| phlebotomine sand flies in the state of piauí, brazil (diptera: psychodidae: phlebotominae). | in 1997, 1998 and 1999 we performed several captures in the state of piauí, in the counties of barro duro, campo maior, castelo, floriano, picos, são raimundo nonato and teresina. we used cdc light traps inside houses, in a primary forest and in one cave. seventeen species were collected being lutzomyia longipalpis, lutzomyia samueli, lutzomyia whitmani and lutzomyia lenti the most captured species. the genus brumptomyia, l. whitmani, lutzomyia sordellii, lutzomyia carmelinoi, lutzomyia termitop ... | 2001 | 11784927 |
| description of evandromyia (aldamyia) orcyi, a new phlebotomine species (diptera: psychodidae: phlebotominae) from the state of mato grosso do sul, brazil. | the genus evandromyia is widely found in brazil, but occurs mainly in brazilian savannah. to date 13 species have been described in the subgenus aldamyia. here we described a new species of evandromyia (aldamyia) collected in the state of mato grosso do sul, brazil. | 2015 | 25884363 |
| analysis of sandflies (diptera: psychodidae) in barra do garças, state of mato grosso, brazil, and the influence of environmental variables on the vector density of lutzomyia longipalpis (lutz & neiva, 1912). | leishmaniasis is an infectious and parasitic zoonotic, non-contagious, vector-borne disease caused by protozoa of the genus leishmania. in brazil, the major vector of leishmania (leishmania) infantum chagasi (cunha & chagas, 1934) is lutzomyia longipalpis. barra do garças, state of mato grosso, was designated as a priority area by the brazilian ministry of health for american visceral leishmaniasis, and it is important to identify the vector species present in this municipality. our objective wa ... | 2012 | 22760128 |
| sandflies (diptera: psychodidae) in an urban area of northeastern brazil. | the sandfly fauna is well studied globally. in brazil, sandfly fauna is very diverse in the northeast region, especially in states such as maranhão, ceará, and bahia. however, in the state of pernambuco, the distribution of these insects is still not well known. therefore, the objective of this study was to identify the different species that constitute the sandfly fauna in an urban area in the northeast region of brazil, where an outbreak of visceral leishmaniasis (vl) was recently reported. | 2017 | 28001216 |
| species diversity of sandflies (diptera: psychodidae) during different seasons and in different environments in the district of taquaruçú, state of tocantins, brazil. | phlebotomine sandflies are the vectors for the protozoan parasites that cause leishmaniasis. the present study investigated the species composition of sandfly fauna in the rural district of taquaruçú, municipality of palmas, state of tocantins, brazil and compared the diversity of species among intradomicile, peridomicile and forest environments during the dry and rainy seasons. sandflies were collected using cdc light traps over the course of three months during the dry and rainy seasons. a tot ... | 2012 | 23147157 |
| ultrastructure of male sex pheromone glands in abdominal tergites of five lutzomyia sandfly species (diptera: psychodidae). | the fine structure of male sex pheromone disseminating structures on abdominal segments of five species of lutzomyia sandflies (diptera: psychodidae) was analyzed. scanning electron microscopy showed that in lutzomyia cruzi [mem. inst. oswaldo cruz 33 (1938) 349] and lutzomyia longipalpis [mem. inst. oswaldo cruz 4 (1912) 84], the disseminating structures are located in pale spots on abdominal tergites iv or iii and iv and are morphologically similar, appearing as small round cuticular elevation ... | 2002 | 18088957 |
| post-engorgement dynamics of haemagglutination activity in the midgut of phlebotomine sandflies. | haemagglutination activity (ha) was studied in gut extracts of both sexes of adults of six sandfly species. ha was sex dependent, with the activity in males more than 50 times lower than that of unfed females. in females, high ha was demonstrable in both the thoracic and abdominal midgut but not in the hindgut. in unfed flies the activity was similar in the midgut wall and the gut contents whereas, in fed females, a high increase was seen in the midgut contents. after blood-feeding, ha was eleva ... | 1996 | 8887335 |
