“…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 of Rangel et al (1985) and Souza et al (1999).

“…A few lines (~ 4%) exhibiting ambiguous intermediate phenotypes (Ward et al 1988) were observed and discarded before colony establishment. 1S and 2S colonies were established and maintained from the sorted IL (~ 34% 1S and ~ 62% 2S) as described in Rangel et al (1985) and Souza et al (1999). The initial crosses were carried out using mainly the F2 and F3 generations of these two colonies.…”

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.

“…This may be as a result of deficient nutrients in the diet offered to larvae and adults (Freire et al, 2001). Some authors point out that survival can be affected by several factors, especially the type of food (Souza et al, 1999), environmental conditions (Ferro et al, 1998) and denial of females to feed on the blood resource provided (Montoya-Lerma et al, 1998).

Lutzomyia cruciata Coquillet (Diptera: Psychodidae: Phlebotominae) is a potential vector of Leishmania sp.; its geographical distribution in Mexico is widespread, but its life history is unknown. The present study gives relevant information on the life cycle, morphology, survival and reproduction of Lu. cruciata observed over successive generations under laboratory conditions. Seven successive generations were produced. A total of 975 adults were obtained in a sexual proportion of 1.1 : 1 (female : male). Each Lu. cruciata female produced 20.7 eggs and 1.9 adults, approximately, with a proportion of eggs per female of 2.7% (first generation) and 21.3% (second generation). The life cycle of Lu. cruciata, from egg to adult, occurred in 52.7 ± 0.52 days. The largest percentage of mortality occurred during the egg stage (48.5%) and the first larval instar (26.5%), whereas in the pupal stage mortality was the lowest (9.1%). Lutzomyia cruciata exhibits sexual dimorphism based on size, which is exhibited as of the second larval instar, males being smaller than females. The maximum survival of females and males was 10 and 15 days, respectively. An overview of the immature stages of the species made with an electronic scanning microscope is included. This paper contributes basic information on aspects of Lu. cruciata that were previously unknown related to its life history.

Effect of Fruit and Leaves of Meliaceae Plants (Azadirachta indicaandMelia azedarach) on the Development ofLutzomyia longipalpisLarvae (Diptera: Psychodidae: Phlebotominae) Under Experimental Conditions

et al. 2009

This no-choice, laboratory study focuses on the feeding of dried, ground, homogeneous powdered, unprocessed fruit and leaves of Azadirachta indica and Melia azedarach to Lutzomyia longipalpis larvae to determine the effects on their mortality and metamorphosis. A. indica and M. azedarach fruit and leaves significantly increased larval mortality in comparison to larvae fed the untreated, standard diet. A. indica fruit and leaves blocked the molting of the larvae to the fourth instar, resulting in them remaining as third instars until the end of the experiment. M. azedarach fruit also blocked the molting of larvae, which remained permanently in the fourth instar. Feeding M. azedarach leaves resulted in greater molt inhibition. All insects in this group stopped their development as second-instar larvae. No antifeedant effect was detected for any experimental treatment. The results indicate that nontoxic, unprocessed materials obtained from A. indica and M. azedarach are potent development inhibitors of L. longipalpis larvae.
