Desenvolvimento de Rhodnius pictipes Stal, 1872 alimentado através de membrana de silicone e em camundongos (Hemiptera, Reduviidae, Triatominae)

Rhodnius pictipes (Hemiptera, Reduviidae) from Serra Norte, State of Pará, Brazil, aclimatized in an insectary at the Laboratório Nacional e Internacional de Referência em Taxonomia de Triatomíneos, Departamento de Entomologia, Instituto Oswaldo Cruz, were fed through a silicone membrane. In order to know the viability and the efficiency of this membrane compared with insects fed on mice, the number of bloodmeals taken, period of development of the five nymphal instars, longevity of adults, average amount of blood intake in each meal and percent of mortality were observed. A total of 310 insects, were used, comprising 50 nymphs of each instar, as well as 30 male and 30 female adults. Insects fed artificially had reduced minimal and maximal periods of development than the group fed on mice. The largest relative increase of body weight was observed in the 2nd instar followed by the 1st, and the amount of blood ingested increased during the development, to the 5th instar for both groups. There were no significant differences between the groups fed artificially and in vivo according to Tukey's test for p>0.05. The percent of mortality in the 1st instar was 18% for artificially fed and 16% for the group fed on mice; these percentages decreased as insects developed until the 4th instar, without mortality, returning to increase in the 5th instar. R. pictipes was shown to be easily adaptable to artificial feeding, and could be considered as an important and viable experimental model.

Dieu, vingt-six portraits bibliques

Vingt-six portraits par vingt-six exégètes. Tel est le défi proposé et assumé pour un parcours surprenant de lectures et d'interprétations multiples d'un Dieu unique et en même temps complexe. Quelle cohérence entre le Dieu fracassant de l'Exode et le Dieu crucifié de l'apôtre Paul ? Quelle continuité entre le Dieu de Gédéon et celui de Jésus : " Mon Dieu, mon Dieu, pourquoi m'as-tu abandonné ? " (Mc 15,34) ? Le Dieu de l'entrée en Canaan ressemble-t-il vraiment à l'Agneau immolé de l'Apocalypse ? Mais déjà, au sein de la Bible hébraïque, les trompettes de Jéricho côtoient le Serviteur souffrant d'Isaïe. Comment comprendre aujourd'hui cette diversité de la présence de Dieu dans la Bible, si ce n'est par la diversité des regards d'exégètes dont la lecture croisée des textes bibliques nous invite à renouveler notre compréhension de Dieu ?

Inequalities Monitoring Update Second Bulletin 2007 (PDF 1952 KB)

Despite some relative improvements, there is a continuing health gap between the most deprived areas and NI overall. This is most evident in the potential years of life lost, infant mortality rates, teenage births, standardised admission rates to hospitals and cancer incidence rates indicators. The suicide rate within deprived areas, although still considerably higher (almost 50% higher), is now closer to the overall NI rate. Despite the reduction in the inequality gap, there was a recent increase in the number of deaths attributed to suicide across all areas. The extent to which this increase in suicides actually indicates an increase in the problem or it is due to recording/reporting practices changing over time has not been established. Life expectancy has been increasing in recent years for both males and females in both deprived areas and NI overall and there is no evidence of a narrowing of the inequality gap. The gap between deprived areas and Northern Ireland was maintained for circulatory and respiratory standardised death rates. The gap between the proportion of the deprived population suffering from a mood or anxiety disorder and that in NI overall has also remained fairly steady. Deprived areas actually fared better than NI generally for relative hospital waiting times and ambulance response times (although this may be an urban issue). åÊ

Rhodnius amazonicus Almeida, Santos & Sposina, 1973, Bona Species, Close to R. pictipes Stål, 1872 (Heteroptera, Reduviidae, Triatominae)

The discovery of two atypical specimens of Rhodnius pictipes Stål, 1872 in French Guiana and the examination of the female holotype of R. amazonicus Almeida, Santos & Sposina, 1973, the only specimen of this species so far known, lead us to propose the rehabilitation of R. amazonicus synonymized with R. pictipes. The male is described for the first time and the female redescribed. Both external characters and genitalia distinguish R. amazonicus from R. pictipes. R. amazonicus shows affinities not only with pictipes but also with R. stali Lent, Jurberg & Galvão, 1993 and R. paraensis Sherlock, Guitton & Miles, 1977. A key is provided for these four species forming, in all likelihood, a natural group, i.e. the "pictipes group".

Development of genital plates in nymphs of Triatoma pallidipennis, Stål 1872, (Hemiptera: Reduviidae) and its application as sexing method

Searching for morphometric differences between sexes in immature forms, the development of genital plates in the exuviae of Triatoma pallidipennis Stål 1872nymphs was studied. Differences were found in the form and size of the 9th genital urosternite, it is larger and wider in males as compared to females. This difference is reported in several South American Triatoma species. From our results it is possible to sex early stages from microscopic observation of genital plates in whole insects.
