| Material currently classified under the name Aricoris constantius (Fabricius, 1793) is examined and found to consist of three distinct species inhabiting southeastern and central Brazil, from the Brazilian state of Bahia to Paraguay. They are A. constantius, A. tutana (Godart, [1824]), reinstated status and A. monotona (Stichel, 1910), reinstated status, the latter two removed from synonymy. Besides significant morphological differences in wing pattern and genitalia, their status as separate species is supported by their overlapping ranges where each phenotype is sympatric with at least one other, with no evidence of hybridization. Notes are provided on the habitat in open formations, range and distribution in south eastern Brasil, and biology, including... |

| The genus Microtypus Ratzeburg, 1848 (Braconidae: Microtypinae) is revised, its species are keyed, and a new species, M. petiolatus van Achterberg spec. nov. is described. The type species is redescribed and fully illustrated. The genus Similearinus Glowacki & Karpinski, 1967 is a new junior synonym of Microtypus; S. ilinskyi Glowacki & Karpiński, 1967 is a new junior synonym of Microtypus trigonus (Nees, 1834), and M. dioryctriae Rohwer, 1920 of M. wesmaelii Ratzeburg, 1848. For both senior synonyms neotypes are designated. The Malagasian species that have been placed in Microtypus are excluded and transferred to the genus Stantonia Ashmead, 1904. |

| Advancing our understanding of ocean biogeochemistry, biology, and ecosystems relies on the ability to make observations both in the ocean and at the critical boundaries between the ocean and other earth systems at relevant spatial and temporal scales. After decades of advancement in ocean observing technologies, one of the key remaining challenges is how to cost-effectively make measurements at the increased resolution necessary for illuminating complex system processes and rapidly evolving changes. In recent years, biogeochemical in situ sensors have been emerging that are threefold or more lower in cost than established technologies; the cost reduction for many biological in situ sensors has also been significant, although the absolute costs are still... |

| Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) was exposed to gammacyhalothrin to study the stimulatory effect of low concentrations of this pyrethroid. The doses studied were 23.4375, 11.7188, 5.8594, 2.9297, 1.4648, 0.7324 mg.litre-1 and water, as control. The third, fourth, and fifth instars of P. nigrispinus were shorter with all the doses of this insecticide. The survival and longevity of this predator was highest with the lowest doses. The oviposition period of P. nigrispinus decreased as the doses increased. The lowest pre-and postoviposition periods were found with 11.7188 mg.litre-1 of gammacyhalothrin. The dose 0.7324 mg.litre-1 increased the clutch interval. The egg viability was similar between the treatments. The number of eggs per... |

| ABSTRACT Animal models have been used in experimental research to increase human knowledge and contribute to finding solutions to biological and biomedical questions. However, increased concern for the welfare of the animals used, and a growing awareness of the concept of animal rights, has brought a greater focus on the related ethical issues. In this review, we intend to give examples on how animals are used in the health research related to some major health problems in Brazil, as well as to stimulate discussion about the application of ethics in the use of animals in research and education, highlighting the role of National Council for the Control of Animal Experimentation (Conselho Nacional de Controle de Experimentação Animal - CONCEA) in these... |

| The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere companion to the Arctic Climate Impact Assessment. |

| The biology of Bemisia tabaci biotype B (Genn.) on bean (Phaseolus vulgaris L.) genotypes containing arcelin in the seeds was evaluated. Also, biochemical screening of seeds and leaves material of these genotypes were carried out in order to verify if traces of arcelin could be found in its leaves. The tests were conducted under greenhouse conditions, in the dry and wet seasons, with the following genotypes: ARC 3s, ARC 5s (wild genotypes containing arcelin in the seeds); ARC 1, ARC 2, ARC 3, ARC 4 (near isogenic lines containing arcelin in the seeds - EMBRAPA) and Porrillo 70, Bolinha, IAPAR MD 808 (commercial genotypes without arcelin). The wild genotypes, ARC 3s and ARC 5s, showed high levels of antibiosis resistance type, mainly for ARC 5s which... |

| Argyrotaenia sphaleropa (Meyrick) is associated with various fruit species in South America. This tortricid was first detected in citrus, Citrus sinensis (L.) Osbeck, in Brazil, in commercial groves in northern Paraná, during the 1994/95-crop season. The aim of this work was to study the biology of this lepidopteran under laboratory conditions (28 ± 2ºC, 70 ± 10% UR, 14h photofase) using the citrus cultivar Pêra. Larvae obtained from egg masses collected in a commercial citrus grove in Rolândia, PR, were individually placed on citrus terminal leaves inside glass shell vials (8.5 x 2.5 cm) until adulthood. A male and a female moth were then transferred to acrylic cages (13 x 10 cm) containing inside a bouquet made with new citrus flush to serve as... |

| Several coleopterans of the Scarabaeidae family (Pleurosticti) are reported as important pests of agricultural crops, but little information on their biology is available. We describe our observations on the biology of adult Cyclocephala verticalis Burmeister collected with light traps from January, 2006 to December, 2007, in Aquidauana, MS, Brasil. Field collected adults were taken to the laboratory and kept in plastic containers containing soil and seedlings of Brachiaria decumbens under controlled conditions (26 ± 1ºC with 12h of photophase). The embrionary period of C. verticalis took 17.2 days in the average. The duration of first-, second- and third-instar larvae was 22.0, 23.7 and 138.1 days in the average, respectively. The prepupal stage took 12.7... |

| The architecture and biology of Euplusia mussitans (Fabricius, 1787) nests were investigated, using trap nests made by wood, which were randomly distributed in a fragment of a coastal sand dunes, in Salvador, Bahia. Brazil (12º56'S and 38º21'W). 10 nests were found in cavities with 1.5 cm in diameter. From them emerged 10 females and 16 males (Sex ratio = 0,38). The nest cells were made of small pieces of bark cemented together with resin. The number of cells in the nests varied from 2 to 4, with females cells at the inner end and males cells towards the entrance. No significant difference was observed (t= 0.7274, P > 0.05) between the medium size for males (6.3 mm ± 0.16) and for females (6.4 mm ± 0.29). The development time of females was longer than... |

| El objetivo de esta tesis es caracterizar las poblaciones naturales de Ulva fasciata en el sector comprendido entre los ríos Quibú y Jaimanitas al oeste de La Habana, típico de costas de emersión del Caribe Occidental, con vistas a su posible explotación. El estudio se realizó entre marzo de 1996 y enero del 2001. Los resultados más importantes permitieron comprobar que la especie U. fasciata no se distribuye de forma similar en todo este sector, en la cobertura algal intervienen de manera decisiva, el tipo de sustrato y la disponibilidad de nutrientes en el medio. Los compuestos del nitrógeno y el fósforo en el agua de mar y las diferencias en la amplitud de variación de los mismos, justifican las diferencias en la morfometría, la biomasa en pie y el... |
