Abstract: During the period of April to November 1994, an investigation was carried out on fauna of Phlebotominac in Ilam province, west of Iran. About 12000 sandflies were caught by sticky trap, light trap and aspirator from different ecological regions and were identified. These sandflies consist of 22 species (11 species from the genus Phlebotomus: Ph. paptasi, Ph.sergenti, Ph.alexandri, Ph.rnajor, Ph.tobbi, Ph.kandelakii, ph.perfiliewi. Ph.balcanicus and Ph.halepensis plus two new species of Phlebotomus and 11 species from the genus Sergentomyia: S. sintoni, S.dentata, S.antennata, S.theodori, S.mervynae, S.pawlowskyi, S.africana, S.clydei , S.tiberiadis , S.iranica and S.squatnipleurs). The two new species from genus Phlebotomus (Ph.nadimi and Ph.ilami) found in this study have been described in detail.

Abstract: due to the spread of the visceral leishmaniasis in brazilian territory, this research was undertaken with the objective to identify the sandfly fauna and aspects of the species? behavior in forest and anthropic environments in paraná state, brazil. the sandfly captures were sporadically carried out in 37 municipalities of the paraná state, during the period from march 2004 to november 2005. each municipality was once visited, when falc?o traps were installed during three consecutive nights in forested fragments and anthropic environments; captures with shannon traps installed in forests and edge of forests, inspection of walls and electric aspiration in domiciles and forested areas were sporadically undertaken. the data analysis was based on estimates of frequency and abundance of the species, by five native landscapes. a total of 38,662 specimens belonging to 23 species were captured. nyssomyia neivai (pinto) (75.6%), ny. whitmani (antunes & coutinho) (10.1%), migonemyia migonei (fran?a) (7.8%), expapillata firmatoi (barreto et al.) (2.1%) and pintomyia fischeri (pinto) (1.6%) together constituted 97.2% of the phlebotomine colletcted. high frequencies of sand flies were found in forests, henhouses, pigpens and domiciles. the three most frequent species have been implicated in transmission of tegumentary leishmaniasis in paraná and in the brazilian southeastern and southern regions. lutzomyia longipalpis (lutz & neiva), the visceral leishmaniasis vector was no found, however lutzomyia gaminariai (cordero et al.), female of which is similar to that of lu. longipalpis was captured, raising the need to investigate its behavior, including as regard to the vectorial competence.

Abstract: phlebotominae sand fly specimens were prepared for histological and physiological studies. different fixatives were tested on sectioned and whole bodied adult females in order to obtain good fixation and provide satisfactory penetration of the embedding media. all fixed specimens were infiltrated (up to seven days under 5oc) and embedded in hydroxyethyl metacrylate. two-three μm sections were stained, mounted in canada balsam and observed by light microscopy. best results were achieved when whole bodied insects were double fixed in bouin's and carnoy's fluids (4 h/2 h) and stained in hematoxilin/eosin or fixed in calcium formaldehyde and stained in mercury bromophenol blue.

Abstract: leishmaniases are endemic to several brazilian states, including minas gerais. as many cases of these diseases are diagnosed in minas gerais every year, this paper aimed to determine the diversity of the species of sandflies vector of leishmaniases, in lassance and corinto on the banks of the velhas river. over two years, 21,014 specimens of sandflies, belonging to 19 species were captured with light traps. of these specimens, nyssomyia neivai (pinto 1926) (84.18%), nyssomyia intermedia (lutz & neiva 1912) (13.41%), evandromyia lenti(mangabeira 1938) (0.99%) and evandromyia sallesi (galv?o & coutinho 1939) (0.48%) were the most represented. the former two species could be involved in the epidemiological chain of leishmaniasis in this region. no significant difference was found between the species compositions on the two river banks.

Abstract: a sand fly fossil was found in amber, a vegetal resin, which allows all the external phlebotomine structures to be seen. the piece that contains the new species is 14 mm long ′ 8 mm wide ′ 3 mm high. all the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eye-piece. the morphological aspects of the new species suggest its inclusion in the pintomyia genus, pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. the presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus pifanomyia. the new species is named pintomyia (pifanomyia) brazilorum sp. nov.

Abstract: several species of the subgenus psychodopygus mangabeira, 1941 are known to be leishmaniosis vectors in brazil. some of them are morphologically similar, which makes their identification quite difficult concerning epidemiological studies. the aim of the current work is to study the morphology of adult specimens of the subgenus psychodopygus, in accordance with the morphological similarity and still taking into account the epidemiological importance of some species. thus 11 species have been studied, including four subspecies of adult specimens deposited in the phlebotomine collection of centro de pesquisas rené rachou-fiocruz. morphological characters found in the literature and new features observed in this study were recorded in a taxonomic discussion format. these characters make it easy to separate such species. four taxa, previously considered as subspecies, were raised to the category of species.

Abstract: this paper deals with the investigation on the composition and stratification of the phebotominae activity developed in patch and clear areas of high agricultural activity. the employment of a cdc light trap proved to be a useful tool in determining the local faune. thirteen species of sandflies and a total of 5,423 individuals were caught. the catch places situated in the ecotone were the ones in which the results reached their best, being outstanding for psychodopygus intermedius, lutzomyia migonei and l. fischeri. thereby, data lead us to believe they have acrodendrophilous habit. on the other hand, when the global results were gathered according to male and female categories, the first one proved to be predominant. in the analysis of seasonal distribution for the three species cited, it was clear that the high-activity peaks were bi- and tri-modal for different seasons. p. intermedius was almost the exclusive sandfly caught at ground level in the autumn season. this exclusiveness has practically extended itself to the catch places situated in open field.
