Dispersão de Orthezia praelonga Douglas, 1891 (Hemiptera: Ortheziidae) causada por equipamentos de pulverização em pomar de citros

A cochonilha O. praelonga é considerada uma importante praga dos citros no Brasil, e informações sobre a sua dispersão estão baseadas apenas em observações empíricas. Objetivou-se avaliar o efeito de equipamentos de pulverização comumente utilizados pelos citricultores na dispersão da praga. Armadilhas adesivas foram instaladas no solo e em vergalhões dispostos verticalmente às plantas de três linhas adjacentes em um talhão de citros contendo plantas infestadas pela praga. Foram adotados equipamentos utilizados para controle de pragas dos citros. A avaliação da dispersão foi realizada por meio da contagem de fêmeas, ninfas ou partes dos insetos aderidas às armadilhas adesivas. Os equipamentos Martignani e Bié foram capazes de lançar a praga a até 15 m, enquanto, para o equipamento Turbo Valência, detectaram-se fragmentos cerosos a até 22 m da máquina. Os equipamentos dotados de pistola não causaram qualquer dispersão da praga. Portanto, evidenciou-se que mesmo a utilização de equipamentos para controle de outras pragas pode favorecer a dispersão da cochonilha O. praelonga em pomares de citros, e isso deve ser considerado no aprimoramento do programa de manejo integrado de pragas dos citros.

O grupo escolar modelo augusto severo (1908-1928): vinte anos de formação de professores

Ce travail a pour objet d'étude le Groupe Scolaire Augusto Severo, situé à Natal, première institution du type dans l'État du Rio Grande do Norte. Il analyse la pratique pédagogique, le modèle d'éducation primaire et d'expérimentation des personnes en formation de l'École Normale de Natal, entre 1908 et l'année de 1928. Dans cette période, se sont produites des tentatives d'organisation scolaire par le biais de la Réforme de l‟Enseignement Primaire (1908) et de la Réforme de l‟Enseignement (1916). Nous nous sommes basés sur l'Histoire Culturelle définie à travers la conjonction de l'histoire des objets dans sa matérialité, des pratiques dans leurs différences et configurations, des dispositifs dans leurs variations. Nous avons utilisé les journaux A República et Diário do Natal, la revue Pedagogium, des Lois, des Décrets et Messages du Gouvernement, des Codes d'Enseignement et le Régime Interne des Groupes Scolaires, documents qui proviennent du fonds de l'Institut Historique et Géographique do Rio Grande do Norte (IHGRN) et des sources iconographiques, provenant de l'Institut du Patrimoine Historique et Artistique National (IPHAN/RN). Dans les Archives Publiques de l‟Etat (APE/RN) nous avons recherché les Livres d'Enregistrement des Groupes Scolaires et Écoles Isolées, Offices, Inscriptions, Rapports et Actes de réunions de la Direction Générale de l'Instruction Publique et Journal de Classe. Nous avons analysé l'action des professeurs dans cette institution primaire, ainsi que l'histoire des disciplines scolaires et des programmes d'enseignement, la problématique des contenus et méthodes. Nous avons observé que la méthode intuitive était la dynamique de la pratique pédagogique efficace et que les rites de récompense, les cérémonies civiques composaient l‟ensemble des idées modernisatrices de l‟époque

Desenvolvimento e capacidade de consumo de Chrysoperla externa (Hagen, 1861) alimentada com ninfas de mosca-branca criadas em hortaliças

Many arthropods are mentioned with whitefly natural enemies, including the green lacewings. The aim of this study is to analyses the development and the capacity of predation of Chrysoperla externa (Hagen, 1861) fed with Bemisia tabaci B biotype nymphs, rearing different vegetables (kale, broccoli, eggplant end tomato). The duration, viability end weight in each stage end phase of development of the insect-predator had been evaluated, as well as the predatory capacity of the larvae in the third instar. The larval phase of the predator presented minor duration when these had been fed with nymphs developed the broccoli (12.36 days) and minor duration of the tomato (14.36 days) phase when fed with nymphs developed in kale, broccoli, and eggplant (6.50, 7.20, 7.33 days, respectively). The lower indices of viability been found for the larvae fed with nymphs developed in the tomato (30%), and average weights have. The predatory capacity of the larvae during the third instar was not affected, independently on the plant host where the whitefly nymph fed itself.

Biomass and Stand Characteristics of a Highly Productive Mixed Douglas-Fir and Western Hemlock Plantation in Coastal Washington

Aboveground biomass predictive equations were developed for a highly productive 47-year-old mixed Douglas-fir and western hemlock stand in southwest Washington State to characterize the preharvest stand attributes for the Fall River Long-Term Site Productivity Study. The equations were developed using detailed biomass data taken from 31 Douglas-fir and 11 western hemlock trees within the original stand. The stand had an average of 615 live trees per hectare, with an average dbh of 35.6 cm (39.1 cm for Douglas-fir and 33.3 cm for western hemlock) and an average total tree height of 31.6 m (32.8 m for Douglas-fir and 30.2 m for western hemlock). Equations developed were of the form In Y = b(1) + b(2) In dbh, where Y = biomass in kg, dbh = diameter in cm at 1.3 m height, b(1) = intercept, and b(2) = slope of equation. Each tree part was estimated separately and also combined into total aboveground biomass. The total aboveground biomass estimation equations were In Y = -0.9950 + 2.0765 In dbh for Douglas-fir, and In Y = -1.6612 + 2.2321 In dbh for western hemlock. The estimate of the aboveground live-free biomass was of 395 Mg ha(-1) (235 Mg ha(-1) for Douglas-fir and 160 Mg ha(-1) for western hemlock), with 9.5, 29.3, 12.9, 308, and 32.7 Mg ha(-1) in the foliage, live branches, dead branches, stem wood, and stem hark, respectively. When compared with biomass estimates from six other studies, ranging in age from 22 to 110 years and from 96.3 to 636 Mg ha(-1), the biomass of the Fall River site was relatively high for its age, indicating very high productivity.

Memórias de uma Escola Isolada Rural: estudo de um Livro de Visitas (1928-1948)

Cet article étudie le livre de visites de l'ancienne école mixte de la Fazenda Ponte Alta/Bela Vista, liée au groupe scolaire de la ville de Bariri, dans l'état de São Paulo (SP). À partir des registres de vingt ans d'activités (1928-1948), nous retraçons les exigences des inspecteurs primaires et si ces exigences provenaient (ou non) de professeurs et de la communauté paysanne pour ébaucher un cadre socio-historique de l'enseignement des premières lettres dans la zone rurale de l'intérieur de l'état de São Paulo. Il en résulte que le discours qui défendait l'égalité de chances pour les populations urbaines et rurales négligeait généralement le besoin de promouvoir l'égalité de conditions pour que la communauté rurale puisse profiter des chances qui lui étaient promises.

First case of an infection of the metacercariae of Austrodiplostomum compactum (Lutz, 1928) (Digenea, Diplostomidae) in Hypostomus regani (Ihering, 1905) (Siluriformes: Loricariidae).

Austrodiplostomum compactum (Lutz, 1928) (Digenea, Diplostomidae) was recorded infecting the eyes of a Hypostomus regani (Ihering, 1905) (Siluriformes: Loricariidae). This is the first report of a loricarid fish infected with A. compactum.

Relata-se a ocorrência de metacercárias de Diplostomum compactum (Trematoda: Diplostomidae) infectando Geophagus brasiliensis (Teleostei: Cichlidae) do reservatório de Barra Bonita, rio Tietê, estado de São Paulo, Brasil. As metacercárias foram coletadas no globo ocular, fixadas em solução de AFA e coradas com carmim. As análises morfológicas e morfométricas de cinco espécimes foram realizadas por meio do sistema computadorizado de analise de imagem. Este foi o primeiro registro da ocorrência desse parasito no reservatório de Barra Bonita e também o primeiro registro em acará Geophagus brasiliensis.

Consumo e ganho de peso de larvas de Chrysoperla Externa (Hagen, 1861) (Neuroptera: Chrysopidae) de diferentes Populaçoes e Geraçoes de Laboratório

Several studies have been made about biology, predatory capacity, and food consumption to crisopids species, trying to get informations to use in Integrated Pest Management. Raising insects in laboratory for many generations could cause blood relation problems, even annihilate the insect mass production. In this way, the objective of this work was to determine the consumption and the weight gain to Chrysoperla externa larvae from two populations and different laboratory generations, founded by 1, 5, 10, 15 and 20 couples. By the result it was possible to conclude that larvae food consumption was higher in populations founded by greater number of couples, and it is not verified variation among populations and generations.

Prevalência, sazonalidade e intensidade de infecção por Diplostomum (Austrodiplostomum) compactum Lutz, 1928 (Digenea, Diplostomidae), em peixes do reservatório de Volta Grande, Estado de Minas Gerais, Brasil

The present study was conducted in the Aquaculture Station of Hydroeletric Power Station situated in Volta Grande Reservoir, MG, Brazil. Seventy freshwater corvinas, Plagiscion squamosissimus, and 66 tucunarés, Cichla ocellaris were captured bimonthly from April 2000 through April 2001 with net and hook. The helmints were identified as Diplostomun (A.) compactmn which showed the highest prevalence in the corvina's eyes in April 2000 (70%), February 2001 (80%) and April 2001 (60%), while in tucunaré occurred in April 2000 (33.3%), August 2000 (18.2%) and October 2000 (18.2%). Nevertheless, increase in the mean intensity of parasites was related in April (6.6), June (6.0), August (18.5) 2000 and February (5.7), April (4.8) 2001 for corvina and in August (16.0) and October (7.0) 2000 for tucunaré. Corvina's females showed infection during all period, while males did not show the same prevalence in June 2000 and April 2001. On the other hand, tucunare's males were infected in all months while females in August and October 2000. The highest prevalence in corvina was observed in the months which presented elevated water temperature (April, October, December 2000 and April 2001). The number of parasites collected in corvina on February 2000 was higher than the one observed in August 2000. The same was not observed for tucunaré. This work demonstrate corvina's high susceptibility to metacercariae of Diplostomum.

Metacercárias de Diplostomum (Austrodiplostomum) compactum Lutz, 1928 (Digenea, Diplostomidae) em peixes do rio Paraná, Brasil. Prevalência, sazonalidade e intensidade de infecção

This paper aims at evaluating the occurrence of Diplostommn (Anstrodiplostomum compactum (Digenea: Diplostomatidae) in the eyeball of Plagioscion sqnamosissimus (corvina) and Cichla ocellaris (tucunaré), monthly captured in Paraná river, Presidente Epitácio, state of São Paulo, Brazil. From 61 corvinas under analysis, 56 of them contained parasites (92%) with intensity rate of 42.0 host parasites. From an amount of 81 tucunarés, 45 contained parasites (55%) with intensity rate of 9.3 parasites. Corvinas showed prevalence from 71 to 100% with the highest intensity rates (103.3 and 106.9) from February to March, 2001. Comparatively, the tucunaré showed the highest prevalence from November 2000 (90%) to February 2001 (80%). The tucunaré highest intensity rates occurred on September, 2000 (12.7), December, 2000 (12.2) and February, 2001 (16.1). Metacercariae showed a hollow womb body and a posterior region of a sinuous conic protuberance, an oral sucker smaller than the acetabulae, a simple acetabulae located in the pre-equatorial region of helminto. A short pre-pharynx followed by a muscular pharynx, genital pore next to acetubulae. Corvina metacercariae presents 1.434,0 μm (880 to 1.840) long by 611.2 ± 93.4 μm (400 to 792) wide. Tucunaré metacercariae, 1.462.4 μm (960 to 2.480) by 710.8 μm (560 to 960). Authors confirmed corvina great susceptibility to Diplomastum and the relationship between the parasitism and the aquatic and climatic parameters.
