Análise de sobrevivência aplicada ao desenvolvimento do pulgão Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) em plantas de pepino (Cucumis sativus L.) contaminadas com fungicidas

It was aimed to evaluate the influence of fungicides utilized in cucumber on the development of the aphid Aphis gossypii Glover under greenhouse conditions. The experimental design was completely randomized with four treatments and 45 replicates, being each plot consisting of a first instar nymph coming from an apterous female in early reproductive period. The fungicides utilized and their respective dosages at g i.a.L(-1) were 800 PM sulphur (1.6), 800 PM mancozeb (1.6) and 840 PM copper oxichloride (1.5). The control was made up of water only. The products did not influence the median time of life in each instar and the nymphal stage, being respectively 1 and 4 days. Copper oxychloride and mancozeb increased the median time of life in days and the total life cycle of the adult stage of this species.

DINÂMICAS MERCANTIS COLONIAIS : Capitania do Rio Grande do Norte (1760-1821)

The size and dynamics of the market producer, consumer and exporter of the Captaincy of Rio Grande do Norte, in the period between 1760 and 1821 is the primary goal of this dissertation. In order to establish relations between the founding of new towns built from 1750 and its incorporation into the water supply and domestic market, showing more specifically the colonial economic relations established between the coast and the hinterland of the Province. Based on references by authors such as Edward Shils and Immanuel Wallerstein have investigated topics such as formation of colonial space, deployment-action of colonial institutions regarding business practices, and the dynamic market of the Province of Rio Grande do Norte.

A Produção do Flagelo : a re-produção do espaço social da seca na cidade de Mossoró (1877-1903-1915)

The great droughts re- produced spaces in the city of Mossoró / RN in the end of the nineteenth century to the beginning of the twentieth century. Its dimension exceeds the climatic effects becoming social locus when advances over the political and economic sectors, social and cultural of the North / Northeast Brazilian societies during that period. This way, analyzing the re-production of social space in episodes of Mossoró‟s droughts is our toil. So try to reveal each segment, route and aspect of production of space in its size and interface between the perceived, conceived and lived, and subjects related to it - refugees, population and authorities - during the droughts of 1877, 1903 and 1915 within Mossoró city. Therefore, issues such as the constitution and representation of the city and social space in the terrifying experience of the drought of 1877, the production of fixed objects and flows of the urban web through of migrant labor, attempts to control, discipline and spatial planning and ways to resistance to these charges in daily sphere are key issues addressed in this work. For this we use diverse sources as minutes of the city council, reports from provincial presidents, media, memory books and others that sustain us in building our narrative and problematic. This way, the spatial production of Mossoró‟s droughts reveals itself in the field of relations and political-economic transformations and sociocultural, inextricably, that shapes and mobilizes your own social space

A new species of Miogryllus Saussure, 1877 from Andean Venezuela with bizarre cephalic morphology (Orthoptera, Gryllidae, Gryllinae, Modicogryllini)

Miogryllus muranyi n. sp. is described from the Andean Acacia-Cactaceae semi-desert bush in the Chama Valley of Venezuela. The species is characterized by the unusual shape of the male head, which makes it readily distinguishable from any other congener known to date.

Aspectos biológicos de Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) em três cultivares de algodoeiro e em três espécies de plantas daninhas

Este trabalho teve como objetivo estudar os aspectos biológicos de A. gossypii em três cultivares de algodoeiro e em três espécies de plantas daninhas. O experimento foi conduzido no Laboratório de Controle Biológico, sob condições controladas de temperatura (25 ± 1ºC), umidade relativa do ar (70 ± 10%) e fotofase (12 horas). Foram utilizados seis tratamentos, correspondendo às cultivares de algodoeiro CNPA ITA 90, Coodetec 402 e Deltaopal e espécies de plantas daninhas: guanxuma (Sida santaremnensis), malva-preta (Sidastrum micranthum) e trapoeraba (Commelina benghalensis). As unidades experimentais (25 repetições) consistiram de placas de Petri contendo ágar-água a 1% solidificado. Nestas placas, os ofídeos foram mantidos individualmente sobre discos foliares (3cm de diâmetro) de seus respectivos tratamentos. Os menores valores, em dias, para a fase ninfal foram obtidos em CNPA ITA 90 (4,39 ± 0,74), Deltaopal (4,45 ± 0,75), Coodetec 402 (4,47 ± 0,75) e trapoeraba (4,75 ± 0,80). O período reprodutivo e a longevidade dos adultos variaram de 8,21 ± 0,85 a 15,52 ± 0,93 e 11,09 ± 0,97 a 24,33 ± 1,59 dias, respectivamente, sobre guanxuma e Deltaopal. As cultivares de algodoeiro são mais favoráveis a A. gossypii que as plantas daninhas e na ausência de plantas de algodoeiro, as plantas daninhas guanxuma, trapoeraba e malva-preta são hospedeiros potenciais para manutenção da população de A. gossypii.

Larval stages of Pyromaia tuberculata (Lockington, 1877) (Decapoda, Majidae, Inachinae) reared in the laboratory

The larval development of Pyromaia tuberculata (Lockington, 1877) is described from specimens reared in the laboratory. Larvae were obtained from ovigerous females collected by trawl in Ubatuba, São Paulo state, Brazil. Rearing was carried out at 24 +/- 1 degrees C in 35 parts per thousand S. The larvae pass through two zoeal stages before moulting to the megalopa. A comparison is made with previously studied majid species occurring in the southern and southeastern regions of Brazil.

A new species of Pterodectes Robin, 1877 (Proctophyllodidae: Pterodectinae) from the pale-breasted thrush, Turdus leucomelas (Passeriformes: Turdidae)

A new species of feather mite, Pterodectes fissuratus sp. n., is described from the pale-breasted thrush, Turdus leucomelas Veillot (Passeriformes: Turdidae), in Brazil. This species is easily distinguished by having numerous well-pronounced lacunae and a longitudinal median furrow on prodorsal and hysteronotal shields in both sexes. Copyright © 2005 Magnolia Press.
