“…The Lu. longipalpis population of Espírito Santo do Pinhal is characterised by a sex pheromone that differs from that found in populations from the western region of SP (Casanova et al 2006). Identifying population parameters that indicate vector capacity is essential to understanding the different epidemiological patterns of AVL within the state.…”

Previous studies demonstrated that L. neivai is the predominant species in this area (Casanova et al 1995, Casanova 2000.Mark-release-recapture experiments -Mark-releaserecapture experiments were performed with wild-caught sand flies from August 1999 to April 2000.The sand flies were caught using the Castro aspirator (Alexander 2000) in modified Shannon traps (Vexenat et al 1986) from 18 h to 21 h. The sand flies were counted and transferred to a Styrofoam cage (20 × 13 × 18 cm) with a thin layer plaster of Paris ( Fig. 2) and then marked with fluorescent powder (red, white, yellow, and blue -Bioquip Inc.) according to the date and site.…”

The dispersal pattern of the sand fly Lutzomyia neivai was studied through mark-release-recapture experiments in an American cutaneous leishmaniasis endemic rural area in Southeastern Brazil. Over 6500 specimens were marked with fluorescent powder and released in forest edge and peridomicile habitats from August to November 1999, February and April 2000. Recapture attempts were made using Shannon and CDC traps up Key words: mark-release-recapture -dispersal -sand fly -Lutzomyia neivai -Brazil Information on the dispersion pattern of sand flies vectors in nature can be used to evaluate the potential rate of Leishmania dissemination and to implement surveillance and control strategies against these vectors.Previous dispersal studies have shown that species from Old World arid and semi-arid regions may fly more than 1500 m (Killick-Kendrick et al. 1984, Doha et al. 1991, while sand flies from Neotropical forests seldom travel no more than 200 m from their release point (Chaniotis et al. 1974, Alexander 1987, Alexander & Young 1992, Morrison et al. 1993.In Brazil, the Lutzomyia longipalpis (Lutz & Neiva) dispersal patterns have been studied (Dye et al. 1991, Kelly & Dye 1997, but there is no study of the dispersal pattern of the vectors of American cutaneous leishmaniasis (ACL). In the Southeastern region of Brazil, the forest seems to be the environment of the enzootic cycle of Leishmania (Viannia) braziliensis (Gomes et al. 1989, Gomes 1994, Lainson et al. 1994, and it is mostly in the domiciliary habitat that man becomes infected (Rangel et al. 1990, Gomes 1994, Tolezano 1994, Gontijo et al. 2002. Thus the flight range and the dispersion of sand flies between these habitats are important factors in ACL transmission.The present study was carried out to describe the dispersal pattern of Lutzomyia neivai (Pinto, 1926), recently resurrected as species of the complex Lutzomyia intermedia (Lutz & Neiva, 1912) by Marcondes (1996), in an ACL endemic rural area in Southeastern of Brazil, by the mark-release-recapture technique. The anthropophilic behavior of the species, its predominance in modified environments and its presence in houses were people have become infected indicates L. neivai as the suspected vector in a large area (Gomes 1994, Tolezano 1994, Casanova et al. 1995, Marcondes et al. 1998, Teodoro et al. 2001, Salomon et al. 2003, 2004, Andrade Filho et al. 2003. MATERIALS AND METHODSStudy area -The study was carried out in an ACL endemic rural area in municipality of Conchal (22°18'S and 47°13'W), Mogi Guaçu River Valley, São Paulo (Fig. 1). This locality has a secondary remnant gallery forest, which covers the left margin of Mogi Guaçu river (Fig. 1), small farms with fruit-trees, vegetables, and domestics animals such as chickens and pigs. According to the Köeppen classification, the climate is subtropical warm with dry winter (Cwa). The average annual rainfall is 1381 mm and the average annual temperature is 21.6°C.

Section: Lutzomyia Longipalpis Sl Occurs From Argentina Tomentioning

confidence: 99%

“…Longipalpis s.l. males produce copulatory "lovesongs" (Souza et al 2002 and pheromones (Hamilton et al 1996a,b, 2005, Casanova et al 2006) that show striking differences between populations suggesting that those acoustic and chemical signals have a role in the observed insemination failures.The results presented in Table I and II also show evidence for pre-mating reproductive isolation as summarized in the Figure. While copulations were observed in nearly half of the attempted homospecific crosses (0.465 ± 0.042), only about 25% (0.258 ± 0.030) of copulations were observed in heterospecific crosses among allopatric populations. This difference is highly significant (t = 4.125; d.f.…”

Lutzomyia longipalpis s.l. occurs from Argentina to Mexico (Young & Duncan 1994) and because of its wide distribution there have been doubts expressed that this taxon is a single species. Mangabeira (1969) commented on morphological variation seen in males. He observed that specimens captured in the state of Pará, North Brazil, bore a single pair of pale tergal spots on abdominal segment IV (1S males) and those captured from the Northeastern state of Ceará (CE) showed an additional pair of spots on segment III (2S males). Mangabeira commented that the two forms were found in different ecological conditions and speculated that they might represent two species. The existence of a complex was confirmed by Ward et al. (1983Ward et al. ( , 1988 and Lanzaro et al. (1993) in crossing experiments, although the male spot phenotype turned out to be only useful as a morphological marker of different species in some localities such as Sobral, CE (see below) (reviewed in Bauzer et al. 2007).In Brazil, Lutzomyia longipalpis s. l. (Lutz & Neiva, 1912) is without any doubt the principal vector of American visceral leishmaniasis (AVL). It is present in nearly all of the foci of visceral leishmaniasis, is highly anthropophilic as well as readily feeding on dogs and foxes which act as reservoirs of Leishamania chagasi which are frequently found infected (reviewed in Lainson & Rangel 2005).Analysis of male copulatory courtship songs (Souza et al. 2002 and pheromones (Ward et al. 1988, Hamilton et al. 1996a,b, 2005 The best studied populations in Brazil, from an evolutionary point of view, are located in Jacobina (state of Bahía), Lapinha Cave in Lagoa Santa (state of Minas Gerais), Natal (state of Rio Grande do Norte) and Sobral (CE) (Bauzer et al. 2007). The first three localities represent different allopatric siblings (Bauzer et al. 2002b, Bottecchia et al. 2004, Watts et al. 2005) while in Sobral two species coexist in sympatry (Bauzer et al. 2002a, Maingon et al. 2003, Bottecchia et al. 2004. In the present study we compared the reproductive isolation among the three allopatric populations and between the Sobral sympatric siblings.Initially samples of the populations of Jacobina, Lapinha and Natal were obtained using CDC traps (4 to 9 traps in each locality). All males collected in Lapinha had a single pair of spots (1S) in segment IV and all males from Jacobina were 2S (two pairs in segments III and IV, with similar sizes). The majority of males from Natal had the intermediate phenotype, with the extra pair in segment III with less than 3/4 of the size of the spots in segment IV (see Ward et al. 1988). The population from Natal is highly polymorphic for the male spot phenotype but in this locality there is no evidence for the existence of sympatric sibling species (Mukhopadhyay et al. 1998, Bauzer et al. 2002b, Bottecchia et al. 2004, Watts et al. 2005. Eggs from 100 to 200 wild-caught females from each of the three localities were used to establish laboratory colonies following the methodologies 217 Reproductive isolation...
