This study aimed to assess the prevalence of contraceptive use by adolescents. A cross-sectional study was performed from March to September 2002 in a representative sample of adolescents 15 to 18 years of age in the urban area of Pelotas, Rio Grande do Sul State, Brazil. Multiple-stage sampling was used, and in the 448 census tracts located in the urban area, 90 were sampled and households were visited in each tract. Information was collected on sexual initiation and use of contraceptive methods. Chi-square test was used to compare proportions. The sample included 960 adolescents. 88% of subjects reported the use of any contraceptive method. Condoms were the most commonly used method (63.2%). Low adolescent schooling was the only variable associated with increased risk of non-use of contraceptives. Condom use was higher among males, adolescents whose mothers had 9 or more years of schooling, and those reporting several sexual partners in the previous year. Condoms were the most commonly used contraceptive method.

Semideciduous Seasonal Forest

This study aimed to compare the mosquito fauna found in three remnant forest fragments of a semideciduous seasonal forest by using oviposition traps in the northwestern region of the state of Rio Grande do Sul, Brazil. Between 2018 and 2019, larvae were collected quarterly in three forest fragments, one situated in an urban area, another in a rural area close to the city and a third formed by an extensive area of native forest far from the urban environment. Four species were caught: Aedes terrens (Walker, 1856) (282), Limatus durhamii Theobald, 1901 (30), Aedes aegypti (Linnaeus, 1762) (23) and Toxorhynchites theobaldi (Dyar and Knab, 1906) (6). The Morisita-Horn index indicated a high similarity between the fragments studied (>80%). The mean number of mosquitoes collected. in the rural area was significantly higher than in the other areas (F = 6.073; d.f. = 17; p <0.05). The calculation of the phi coefficient to assess the co-occurrence of two species in the same trap did not indicate significant values (p> 0.05). Aedes terrens demonstrated a good ability to colonize and inhabit the different types of forest fragments studied. In addition, the forest fragment located in a rural area close to the urban area offered conditions for the survival of species of wild and urban mosquitoes, such as Ae. aegypti.

This study aimed to know the species of frugivorous flies (Tephritidae and Lonchaeidae) and their parasitoids associated with fruits in home orchards. It was conducted in the Gurgueia Valley, municipality of Bom Jesus, Piauí, Brazil. Fruit collection was carried out from April to December 2016. A total of 959 fruits (12 kg) belonging to seven fruit species were sampled, such as acerola (Malpighia glabra), carambola (Averrhoa carambola), lime (Citrus aurantifolia), balsam pear (Momordica charantia), cherry of the Rio Grande (Eugenia involucrata), umbu-cajá (Spondias bahiensis), and purple mombin (Spondias purpurea). Only three among these species (acerola, umbu-cajá, and purple mombin) were host, with 2,770 frugivorous flies. Umbu-cajá hosted 316 specimens of Anastrepha obliqua, from which puparia have emerged 84 specimens of Opius bellus and four of Pachycrepoideus vindemmiae. Purple mombin hosted Ceratitis capitata (2,384 specimens), Neosilba pendula (69 specimens), and Anastrepha sp. (one male). Eleven specimens of Tetrastichus giffardianus emerged from the puparia of C. capitata. Acerola hosted only one female of C. capitata and six specimens of N. pendula. Ceratitis capitata and N. pendula were recorded for the first-time infesting fruits of purple mombin in Piauí. Tetrastichus giffardianus parasitizing C. capitata in purple mombin was first recorded in the state of Piauí. Pachycrepoideus vindemmiae is a new record in A. obliqua in umbu-cajá in Brazil.

A importância de estudos e mapeamentos relacionados às inundações é observada pelo expressivo aumento das pesquisas nas últimas décadas. O município de São Gabriel, no Estado do Rio Grande do Sul, possui mais de 80% de sua população na área urbana. Parte desta população se localiza no entorno do Rio Vacacaí e tem sido afetada seguidamente por inundações. Este estudo teve por objetivo o mapeamento das áreas com suscetibilidade e perigo de inundação na área urbana de São Gabriel. Os procedimentos metodológicos envolveram o levantamento e o processamento de imagens de satélite e dados topográficos que permitiram a análise e a síntese dos mapas e informações derivadas. A partir da análise de um recorte temporal de trinta anos verificou-se que em dezesseis anos há registros de inundações. No total destes dezesseis anos de eventos foram registrados trinta e dois casos em que a população foi afetada com inundações. A área total de suscetibilidade é 3,57 Km², representando 7,75% de toda a área urbana. As áreas de perigo cobrem 0,62 Km², representando 17,36% da suscetibilidade e 1,34% da área urbana do município. Este mapeamento representa uma importante ferramenta para subsidiar a prevenção e a redução de desastres naturais associados às inundações na área de estudo. Abstract DEFINITION OF FLOOD HAZARD AREAS VACACAÍ RIVER IN THE CITY OF SAN GABRIEL, RS The importance of studies related to flooding and mappings can be observed by the significant increase in research in recent decades. The municipality of São Gabriel, Rio Grande do Su State, has more than 80% of its population in urban areas. Part of this population is located in the nearness of Rio Vacacaí and has subsequently been affected by flood events. This study aims to map the areas with susceptibility and hazard of flooding in the urban area of São Gabriel. The methodological procedures involved the inventory of events, collection and processing of satellite images and topographic data. The analysis and synthesis of information derived from maps. From the analysis of the thirty years it was found that in sixteen years have records of flooding. A total of sixteen years of events were recorded thirty- -two where the population was affected with floods. The total susceptibility area is 3.57Km², representing 7.75% of the entire urban area. The danger areas are added to 0.62Km², representing 17.36% within the susceptibility and 1.34% compared to the urban area.

Although studies on drosophilid (Diptera, Drosophilidae) assemblages have become relatively abundant in the past decades, many environments remain to be searched. The present study investigates the composition, the species abundances and the richness of the drosophilid assemblages in two localities of the municipality of Cruz Alta, northwestern region of the state of Rio Grande do Sul, a point of contact between the biomes Atlantic Forest and Pampa: (i) an urban area (2007), constituted by a domestic orchard with Citrus trees, and (ii) a forested area, in Centro de Educação, Pesquisa e Proteção Ambiental - CEPPA (2008/2009), of Universidade de Cruz Alta, located in a fragment of riparian forest. Collections were conducted using fermented banana-baited traps and repeated periodically. A total of 7,428 individuals were caught, belonging to two subfamilies, six genera and 53 species. In the urban area, 22 species were found, from two genera (N = 2,421), while in the forested area 46 species were found, from six genera (N = 5,007). Six exotic species were found, markedly more abundant in the urban area, where they corresponded to 95% of the specimens, in comparison to 50% in the forest. Between the Neotropical species, the most common were Drosophila maculifrons Duda and D. polymorpha Dobzhansky & Pavan. Only D. simulans Sturtevant was captured in all samples in both localities. The present survey represents the first records for the state of Rio Grande do Sul of the D. canalinea and D. virilis species groups and the species D. arassari Cunha & Frota-Pessoa, D. fuscolineata Duda, D. nigricruria Patterson & Mainland, D. papei Bächli & Vilela, D. senei Vilela, D. trifilum Frota-Pessoa, D. virilis Sturtevant, Leucophenga maculosa (Coquillett) and Rhinoleucophenga obesa (Loew). Furthermore, it also represents the first record for the state of the genera Amiota Loew, Leucophenga Mik and Rhinoleucophenga Hendel and of the subfamily Steganinae. So, the present survey raises the number of drosophilid species recorded for the state from 66 to 75, the number of genera from five to eight, and subfamilies from one to two.
