13. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

14. Baixa diversidade genética em Culex quinquefasciatus (Diptera: Culicidae) infectado por Wolbachia do Brasil e Argentina
Culex quinquefasciatus é vetor de patógenos humanos, incluindo nematódeos filarídeos e vários vírus. Embora a sua relevância epidemiológica varie entre as diferentes regiões geográficas, o conhecimento da estrutura genética da população é ainda incipiente. Em vista disso, foram avaliados os níveis de diversidade genética de Cx. quinquefasciat

15. Kinetic of water diffusion and color stability of a resin composite as a function of the curing tip distance
The influence of curing tip distance and storage time in the kinetics of water diffusion (water sorption-W SP, solubility-W SB, and net water uptake) and color stability of a composite were evaluated. Composite samples were polymerized at different distances (5, 10, and 15 mm) and compared to a control group (0 mm). After desiccation, the specimens were stor

16. High prevalence and lack of diversity of Wolbachia pipientis in Aedes albopictus populations from Northeast Brazil
The use of Wolbachia as a tool to control insect vectors has recently been suggested. In this context, studies on the prevalence and diversity of this bacterium in wild populations are relevant. Here, we evaluated the diversity of two Wolbachiagenes (ftsZ and wsp) and the prevalence of this endosymbiont in wild Aedes albopictus. Using semi-nested polymerase

17. Variations in the sensitivity of different primers for detecting Wolbachia in Anastrepha (diptera: tephritidae)
Wolbachia are endosymbiont bacteria of the family Rickettsiacea that are widespread in invertebrates and occur between 20% and 60% of Neotropical insects. These bacteria are responsible for reproductive phenomena such as cytoplasmic incompatibility, male killing, feminization and parthenogenesis. Supergroups A and B of Wolbachia are common in insects and can

18. Wolbachia screening in spiders and assessment of horizontal transmission between predator and prey
Recent studies have revealed that the prevalence of Wolbachia in arthropods is attributable not only to its vertical transmission, but also to its horizontal transfer. In order to assess the horizontal transmission of Wolbachia between predator and prey, arthropods belonging to 11 spider families and six insect families were collected in the same field of ri

19. As consoantes geminadas do italiano : análise de sua produção por falantes italianos e por aprendizes brasileiros
In this dissertation, we investigate the geminate consonants of Italian using production data collected from Italian speakers and Brazilian learners who take undergraduate courses at the Italian Section of the Federal University of Rio Grande do Sul (UFRGS). The general question that guided our acoustic and phonological analysis is whether Brazilian speakers

20. Estratégias para elaboração de um plano de segurança da água para abastecimento humano do município do Natal/RN
A pesquisa trata da análise da produção e distribuição de água potável com qualidade e segurança de modo a atender as necessidades do Homem. Aborda as recomendações da Organização Mundial de Saúde (OMS) para a adoção, por parte das empresas responsáveis pela produção e distribuição de água, de metodologias de avaliação e gestão de ris

21. Wolbachia e incompatibilidade citoplasmática em Anastrepha sp. 1 aff. fraterculus e A. obliqua (Diptera: Tephritidae) / Wolbachia and cytoplasmic incompatibility into Anastrepha sp.1 aff. fraterculus and Anastrepha obliqua. (Diptera: Tephritidae)
The endosymbiont bacteria Wolbachia are vertically transmitted by the females to its progenies, although horizontal transmission between distinct taxa is also known. One of the most relevant effects caused by these bacteria in the reproductive behavior of its hosts is the cytoplasmic incompatibility (CI). Wolbachia was described in several groups of arthropo

22. Genetic divergence of sub samples of tomato germplasm bank the vegetables of the UFV / Divergência genética entre subamostras de tomateiro do banco de germoplasma de hortaliças da UFV
It is up to the enhancers that use the sub-samples that is of the Germplasm Bank to make available genetic resources for the programs of enhancements, given that for the success of any pre-program of enhancement it is necessary to have the knowledge of the amount of existing variation of the specie being analyzed. The genetic resources of the Germplasm Bank

23. Wolbachia in two populations of Melittobia digitata Dahms (Hymenoptera: Eulophidae)
We investigated two populations of Melittobia digitata Dahms, a gregarious parasitoid (primarily upon a wide range of solitary bees, wasps, and flies), in search of Wolbachia infection. The first population, from Xalapa, Mexico, was originally collected from and reared on Mexican fruit fly pupae, Anastrepha ludens Loew (Diptera: Tephritidae); the other, from

24. Corn yield and phosporus loss potential in an Ultisol fertilized with poultry litter / Produtividade de milho e potencial de perdas de fósforo em Argissolo fertilizado com cama de frango
A utilização de resíduos orgânicos na agricultura como fertilizantes ou condicionadores de solo tem ganho importância no Brasil na medida em que a agricultura orgânica tem expandido e os preços de fertilizantes tem aumentado sobremaneira. Contudo, estudos que relacionem as taxas de aplicação de fertilizantes orgânicos, tais como a cama de frango (P
