| Assycuera gen. n. (type species: Anyclocera macroteta Bates, 1880) is proposed to accomodate four species formerly placed in Ancylocera Audinet-Serville, 1834: Assycuera waterhousei (White, 1855) comb, n., Assycuera macrotela (Bates, 1880) comb, n., Assycuera rubella (Bates, 1892), comb. n. and Assycuera scabricollis (Chemsak, 1963) comb. n. The characters used to assemble these species into the new genus were mainly the gradually clavate femora and the antennae of the male with the 11th segment elongate, filiform, the scape not enlarged at base and the pedicel not projected outerly. All the species are redescribed, illustrated and keyed. The males of Assycuera scabricollis and A. rubella are described for the first time. The key presented by Monné... |

| Feeding behavior of the larvae's prawn, Macrobrachium rosenbergii De Man, 1879, in each stage of development was studied face alArtemia Linnaeus, 1758 nauplii, dry and wet diets. Groups of ten larvae in each stage were placed in 500 ml beakers at 29ºC in filtered brackish water. After the fasting period of acclimatization, the three types of food were offered separately to the larvae and the feeding behavior was observed during 30 min. Feeding perception, capture, grasp and ingestion of food were used to determine feeding pattern. Stage I lawac do not eat. The feeding behavior of larvae was similar on the stages II - XI. The perception in distance does not occur in most individuais; the feeding process generally started with the physrcal contact of food... |

| This paper reports the preliminary results of two years of herpetogeographic studies in the region called «Grande Porto Alegre» at its northern portion. The physiognomy shows, at North, slopes of the Brazilian Southern Plateau, more or less forested in a general view; these elevations graãuálly decrease to the South until the levei of the sea to Atlantic littoral by the eastern border, and to Rio Grande do Sul savanah, which extends to Uruguay and Argentina. The biota is transitional from the highland prairies and forests of the plateau to lowland prairies of the pampas. Three faunistic Provinces are included: Guarani, Pampean, and Tupi. The most conspicuous dispersion is shown by the taxa proceeding from the plateau to savanah (Dispersion Centre Guarani);... |

| The population biology of Exhippolysmata oplophoroides (Holthuis, 1948) was studied in Ubatuba Bay (23º26'S, 45º02'W), Ubatuba, São Paulo, Brazil, from September/1995 to August/1996. Each sampling comprised eight transects (14 000 m² each), sampled monthly with three repetitions. The specimens were classified with respect to the presence or absence of eggs in the abdominal appendages. Spine-shrimps occurred only on six transects, being most abundant on transect II, with the highest incidence in late spring and throughout the summer months. Ovigerous and non-ovigerous shrimps were present year-round, in an approximately similar proportion (1:1). Site II in Ubatuba Bay is characterized by high salinity and oxygen values, temperature between 26 and 29ºC, low... |

| Natural occurrence of nuclear polyhedrosis viruses were detected in populations of some Heliconiini in the field as well as in the laboratory. The epizootics appeared under field conditions in populations of Dione juno juno, D. moneta and Agraulis vanillae maculosa. In the laboratory, however, larvae of Heliconius numata mirus, H. hecale vetustus and H. erato phyllis in addition to two hybrids and Eueides Isabella dianasa, all suffered the same disease. The effect of several factors which might contribute to the occurrence of the disease are discussed. Symptoms, histopathology and description of viral particles and polyhedra are given. |

| A sandfly survey was carried out in 100 x 150 m patches of primary forest submitted to recent deforestation in order to determine its species composition 10-30 days after clearing. The following collecting methods were used: CDC traps whit black light; Malaise traps placed at 0.5, 1, 5 and 10m up from the the soil surface; Pennsylvania traps whit black light; Malaise traps, tree-base catches and human baits. A total of 2810 specimens of Lutzomyia França, 1924 and one species of Brumptomyia França & Parrot, 1921, were collected. In general, the predominant species were L. chagasi (Costa Lima, 1941) (25.9%), L. davisi (Root, 1934) (12.3%), L. ayrozai (Barretto & Coutinho, 1940) (9.32%) and L. ubiquitalis (Mangabeira, 1942), (6.93%).

| Four places in Latin-America have Melipona Illiger, 1806 beekeeping: Mexico, with M. beecheii Bennet, 1831; Northeast Brasil, with M. scutellaris Latreille, 1811; Maranhão State (Brazil) with M. compressipes fasciculata Smith, 1854; Venezuela, in her coast, with M. favosa (Fabricius, 1798). Natural colonies of M. compressipes fasciculata occupied tree holes ranging from 6,5 to 24 1. The average honey production of 60 colonies in hives with capacity of 50.2 1, 41.0, 30.2, 16.5 and 6.2 were respectively 8.4, 6.5, 5.5, 3.3 and 2.0 Kg. Due to lack of bee flowers within the city limits, hives with a volume of 27 1 (30x30x30 cm) were used successfully in our future experiments with M. compressipes fasciculata instead of the ideal size of 40 to 50 liters, since... |

| The genus Helvetia Peckham & Peckham, 1894 is revised. The species H. zebrina Simon, 1901 and H. zonata Simon, 1901 are synonymized with H. cancrimana (Taczanowski, 1872). The species H. insularis (Banks, 1902) is synonymized with H. albovittata Simon, 1901. The genus Deloripa Simon, 1901 is considered a junior synonym of Helvetia by transfer of its type species, resulting in the new combination Helvetia semialba (Simon, 1901). The species Cotinusa humillima Mello-Leitão, 1943, transferred to Helvetia by Galiano, is revalidated. Helvetia roeweri (Soares & Camargo, 1948) comb. nov. is transferred from the genus Naubolus Simon, 1901. The epigynal structures of the type species H. santarema Peckham & Peckham, 1894 and those of H.... |

| Este trabalho foi realizado no Manguezal de Itacuruçá, na Baía de Sepetiba com o objetivo de analisar a estrutura populacional das espécies de Uca Leach, 1814. Foram realizadas coletas de junho/2005 a maio/2006, durante as marés baixas. Os caranguejos foram capturados manualmente por duas pessoas e durante 15 minutos. Um total de 2580 animais foi coletado, sendo 1465 machos e 1115 fêmeas. Com relação ao tamanho dos indivíduos, observou-se que os animais do Manguezal de Itacuruçá, de maneira geral, apresentam tamanhos menores que os encontrados em outros manguezais do Brasil. Contudo, os machos atingiram tamanhos maiores do que as fêmeas. A distribuição de freqüência em todas as classes de tamanho foi unimodal para a maioria das espécies, com exceção de U.... |
