La recolonización de las comunidades de Mitílidos en la costa central del Perú de El Niño 1982-83

Se estudia la recuperación de los bancos de los mitílidos Aulacomya ater y Semimytilus algosus después de agosto de 1983 en la Bahía de Ancón y después de agosto de 1986 en Bahía Independencia. En la Bahía de Ancón la recolonización de Semimytilus algosus se inició en octubre de 1983, sostenida por una intensiva proliferación de larvas en el plancton. En febrero de 1984 alcanz.aban una máxima longitud de 31mm y los otros constituyentes de la comunidad estaban completando su recuperación. Sin embargo, hasta marzo de 1987 no habían evidencias de una recuperación de A. ater. En Bahía Independencia hubo una recuperación de S. algosus en el nivel intermareal. En agosto de 1986 recién encontramos una recolonización simultánea de ambos mitílidos en los rizoides de las algas pardas (Macrocystis pyrifera y Lessonia spp.). En los meses posteriores las algas pardas extendieron su distribución vertical de los 6 m hasta más de 12 m de profundidad y junto con ellos también A. ater. Se discute los mecanismos y procesos que estarían implicados en la diferente recolonización de las comunidades de mitílidos en las orillas y fondos rocosos de las dos áreas de estudio.

Bionomic data and larval density of Scarabaeidae (Pleurosticti) in sugarcane in the central region of Mato Grosso do Sul, Brazil

Bionomic data and larval density of Scarabaeidae (Pleurosticti) in sugarcane in the central region of Mato Grosso do Sul, Brazil. Phytophagous larvae of Scarabaeidae cause damage to diverse crops. Information on these pests is scarce; therefore, the objective of this study was to determine biological aspects and larval density of species occurring in an area of sugarcane. The studies were developed in Sidrolândia from April 2009 to March 2010. Scarab beetle larvae were collected in sugarcane roots every fifteen days, taken to the laboratory and reared to obtain the adults and determine biological parameters. A total of 2,656 larvae were collected, being 162 Liogenys fuscus, 120 Cyclocephala verticalis, 37 Cyclocephala forsteri, and 2337 Anomonyx sp. In January, 53.65 larvae m-2 were obtained, and the most abundant species was Anomonyx sp, representing 87.99% of the total larvae collected. From November to March, the greatest densities of Anomonyx were observed in the field. The adults of this species occurred from May to September, and egg laying from September to November. Eggs measured 1.1 x 1.7 mm, and incubation period last 15.4 days. First instar larvae were observed mainly in October; second instar larvae from November to April; and third instar from January to July. Pupae were observed from May to August. The most abundant scarab beetle, Anomonyx sp. in roots of sugarcane presents one generation per year in Sidrolândia, MS.

A Reinserção Social dos Reclusos da Cadeia Central da Praia

O presente trabalho tem como tema a Reinserção Social dos Reclusos da Cadeia Central da Praia. Pretende-se com este estudo conhecer as oportunidades que os reclusos da Cadeia Central da Praia têm de aceder a elementos fundamentais para o processo da sua Reinserção Social, tais como: a educação, trabalho, o apoio da família, apoio social na cadeia e oportunidades de contacto com a comunidade antes da sua reintegração na comunidade. Adicionalmente, pretende-se estabelecer a importância destes factores para a Reinserção Social dos Reclusos ao comparar as oportunidades de acesso a estes elementos de reclusos reincidentes e dos condenados pela primeira vez. A hipótese formulada neste estudo é que o acesso ao estudo, ao trabalho e o contacto com a comunidade contribui para uma melhor Reinserção Social dos reclusos da Cadeia Central da Praia. A pesquisa incidiu numa amostra de 60 reclusos extraída da população da Cadeia Central da Praia, que ronda os cerca de 600 presos. A amostra foi constituída atendendo ao equilibro desejado para a variável reincidente / preso pela primeira vez, e recorreu aos presos indicados pela direcção do estabelecimento que se mostraram disponíveis para participar no estudo. Dos 60 reclusos, todos do sexo masculino, 12 são presos preventivos reincidentes, 26 são presos condenados reincidentes e 22 são presos condenados pela primeira vez. Para a recolha de dados recorreu-se a um questionário, aplicado durante uma entrevista individual. O questionário constituiu-se de 41 questões fechadas, cobrindo aspectos ligados à: identificação do preso, actividades desenvolvidas na cadeia, nomeadamente o ensino, actividades sócio – económicas, a relação com a família, a relação actual com a comunidade, actividade comunitária fora do espaço prisional, a preparação para a liberdade, e uma questão aberta, sobre a relação entre a detenção e mudança de comportamento.

Sand flies (Diptera, Psychodidae, Phlebotominae) from Central Amazonia and four new records for the Amazonas state, Brazil

Sand flies from Central Amazonia and four new records for the Amazonas state, Brazil. A survey was conducted in May and June 2008 to study the fauna of insects in Central Amazonia, Brazil. As part of the survey, we report here that sixty species of phlebotomine were identified, totaling 13,712 specimens from 13 genera. The collection sites were located at the border between the states of Pará and Amazonas, comprising three municipalities from the Amazonas state (Borba, Maués, and Nhamundá). Malaise, CDC and Shannon traps were used to collect the insects. Most of the sand flies were collected by CDC traps (89.5%), while Malaise and Shannon traps collected 7% and 3.5%, respectively. The most abundant genera, representing 97.1% of the total sand flies identified were: Trichopygomyia Barretto, 1962 (47.6%), Psathyromyia Barretto, 1962 (17.9%), Psychodopygus Mangabeira, 1941 (17.5%) and Trichophoromyia Barretto, 1962 (14.3%). The genera with the largest number of species identified were: Psychodopygus (14), Psathyromyia (10), Evandromyia Mangabeira, 1941 (7), Trichophoromyia (5) and Trichopygomyia (5). The most abundant species was Trichopygomyia trichopyga (Floch & Abonnenc, 1945), which represented 29% of the total sand flies identified. Here we also report new records for four species in the Amazonas state: Ps. complexus (Mangabeira, 1941), Ps. llanosmartinsi Fraiha & Ward, 1980, Ty. pinna (Feliciangeli, Ramirez-Pérez & Ramirez, 1989), and Th. readyi (Ryan, 1986). The results of this study provide new, additional information on the distribution of sand flies in the Amazon and increase the number of species in the Amazonas state from 127 to 131.

Revision of Central American species of Euryomma Stein (Diptera, Fanniidae), with description of two new species and updates of distributional records

Euryomma is the second largest genus within Fanniidae, but only two species, E. panamensis Chillcott, 1958 and E. rettenmeyeri Chillcott, 1958 have been recorded in Central America. In this paper we describe two new species of the genus found in Costa Rica, Euryomma chillcotti sp. nov. (Province of Puntarenas) and Euryomma steini sp. nov. (Provinces of Cartago and Limón). Euryomma tahami Grisales, Wolff & Carvalho, 2012 is recorded for the first time to Costa Rica. Identification key to all species found in Central America, descriptions and re-descriptions of species occurring in the region and illustrations of the terminalia of new species are presented.

Richardia Robineau-Desvoidy (Diptera, Tephritoidea, Richardiidae) from Central Amazon, Brazil

Richardia Robineau-Desvoidy (Diptera, Tephritoidea, Richardiidae) from Central Amazon, Brazil. There are 11 species of Richardia known to Brazil. Of these, only four are known to occur in the Brazilian Amazon Region, where the diversity of Richardia is underestimated. Herein we describe and illustrate Richardia intemperata sp. nov. and Richardia parispina sp. nov. from Amazonas, Brazil. An illustrated key to males from this region is also provided.
