“…Wild male flies were identified to species level by dissecting their genitalia; and for collected females, the genitalia of their laboratory reared F1 males were analyzed. The specimen genitalia of tripunctata group flies was compared to drawings reported by: Frota-Pessoa (1954) , Val (1982) , Vilela & Pereira (1985) , Vilela & Pereira (1986) , Bächli, Vilela & Ratcov (2000) and Vilela, Valente & Basso-da-Silva (2004) .

BackgroundYeasts are a necessary requisite in the diet of most Drosophila species that, in turn, may vector their dispersal in natural environments. Differential attractiveness experiments and the isolation of yeasts consumed by Drosophila may be informative for characterizing this association. Hanseniaspora uvarum is among the most common yeast species isolated from Drosophila crops, with high attractiveness to drosophilids. Saccharomyces cerevisiae has been widely used to collect flies, and it allows broad sampling of almost all local Drosophila species. Pronounced differences in the field concerning Drosophila attractivity to baits seeded with these yeast species have been previously reported. However, few explicit generalizations have been set. Since late fifties, no field experiments of Drosophila attractivity were carried out in the Neotropical region, which is facing shifts in abiotic and biotic factors. Our objective is to characterize preference behavior that mediates the interaction in the wild among Neotropical Drosophila species and yeasts associated with them. We want to set a broad generalization about drosophilids attracted to these yeasts. Here we present the results of a differential attractiveness experiment we carried out in a natural Atlantic Rainforest fragment to assess the preferences of Drosophila species groups to baits inoculated with H. uvarum and S. cerevisiae.MethodsBoth yeast species were cultured in GYMP broth and separately poured in autoclaved mashed banana that was left fermenting. In the field, we collected drosophilids over five arrays of three different baits: non-inoculated autoclaved banana and banana inoculated with each yeast. In the laboratory the drosophilids were sorted to five sets according to their external morphology and/or genitalia: tripunctata; guarani; willistoni; exotic; and the remaining flies pooled in others.Results and ConclusionsUninoculated banana baits attracted virtually no flies. We found significant departures from random distribution over the other two baits (1:1 proportion) for all sets, except the pooled others. Flies of the sets willistoni and exotic preferred H. uvarum over S. cerevisiae, while the remaining sets were more attracted to S. cerevisiae. Previously, various authors reported similar patterns in attraction experiments with S. cerevisiae and H. uvarum. It is also noteworthy that both yeast species have been isolated from natural substrates and crops of Drosophila species. Taken together, these results suggest that the preferences among Drosophila species groups may be reflecting deep and stable relations with yeast species in natural environments. They can be summarized as: forest dwelling species from subgenus Drosophila (such as tripunctata and guarani groups) are attracted to banana baits seeded with S. cerevisiae; while exotic (as D. melanogaster) and subgenus Sophophora species are preferentially attracted to baits seeded with H. uvarum.

“…All dipteran insects were preserved in ethanol 70% until identification. Drosophila samples were counted and identified to species using characters of the external morphology and, in some cases, the male and/or female terminalia, according to the method detailed by BÄCHLI et al (2004) BÄCHLI et al (2000), andVILELA et al (2004) were used. Male and female specimens used for species identification were doublemounted (glued to cardboard tips soon after drying, according to BÄCHLI et al 2004: 3), labeled and deposited as vouchers at the Museu de Zoologia, Universidade de São Paulo (Brazil), and at the collection of Sección Entomología, Departamento de Biología Animal of the Facultad de Ciencias, Universidad de la República, Montevideo (Uruguay).…”

This study investigates the species richness and abundance of Drosophila Fallén, 1823 attracted to dung and carrion baited pitfall traps in natural areas with heterogeneous habitats at the Sierra de Minas, Eastern Serranías, southeastern Uruguay. Collecting was carried out on a monthly basis (May 2002 through April 2003). Drosophilids accounted for 0.84% (n = 131) and 3.61% (n = 158) of the Diptera collected from dung (n = 15,630) and carrion (n = 4,382) pitfall traps, respectively. A total of 12 species were identified, 11 of which belong to the subgenus Drosophila (the richest) and one to the subgenus Sophophora Sturtevant, 1939. Over 90% of the Drosophila specimens collected belong to five species of the subgenus Drosophila, namely D. gaucha Jaeger & Salzano, 1953, D. immigrans Sturtevant, 1921, D. mediovittata Frota-Pessoa, 1954, D. aff. nappae Vilela, Valente & Basso-da-Silva, 2004, and D. ornatifrons Duda, 1927. Drosophila cardini Sturtevant, 1916 is recorded for the first time from Uruguay. Drosophila abundance and species richness in the four habitats sampled in the Uruguayan Eastern Serranías, namely woodlands sierra, riparian forest, pine plantation and grazing grassland, were considered to be a function of habitat conservation. Diversity indices were low in all habitats. Different habitats supported particular coprophilous and necrophilous Drosophila species. The woodland sierra represents the most preserved habitat, and contributed with the highest species richness observed. Drosophila ornatifrons was the dominant species, with a restricted habitat distribution. On the other hand, grazed grassland, an environment modified by livestock management, had the lowest species richness: only a few specimens of D. repleta Wollaston, 1858. Regarding species composition, significant differences were found in some pairwise comparisons of groups of Drosophila species that included D. ornatifrons. Fly attraction to dung can be exploited as an alternative and/or complementary collecting method in ecological studies of Drosophila assemblages in natural areas

“…Moreover because of foraminiferal short life cycles and special habitat requirements, benthic foraminifers are affected by environmental changes and can be used as bio-indicators of pollution in coastal environments (Ferraro et al, 2006). Morphological abnormalities in foraminifer tests are observed in polluted environments and may represent a useful bio-marker for evaluating long-term environmental impacts (Vilela et al, 2004).…”

The present study on the Manzala Lake is to define the environmental state, where the freshwater mollusks play significant roles in the public and veterinary health. Moreover the benthic foraminifers are affected by environmental changes and can be used as bio-indicators of pollution in coastal environments. Several physical and chemical factors are considered as affecting the ecology of snails and other intermediate hosts of diseases have been studied in the present work.The Recent sediment reported in the Manzala Lake illustrated that the whole area is characterized by relatively coarser fractions (silty sand) and located at the western part of the lake.The regional pollution index (RPI) of the studied Manzala Lake bottom sediments are exposed to high pollution levels by Cd, Pb, Ni and Co. Meanwhile, Zn and Cu display low degree of pollution. The highest values of heavy metals are recorded near El-Serw agricultural drain and also, at eastern portion of the lake near Bahr El-Baqar agricultural drain where the industrial region in Port Said country.
