Alterações morfológicas provocadas pela aplicação de um análogo de hormônio juvenil em Dysdercus ruficollis (Linnaeus, 1764) (Hemiptera, Pyrrhocoridae, Pyrrhocorinae)

Dysdercus ruficollis [Linnaeus, 1764), vulgarmente conhecidos como "percevejos manchadores do algodão", foram tratados no início do 5º estádio ninfal com um análogo do hormônio juvenil (N(5-cloro-2-metilfenil)-3,7-dimetil-2,6-octadienilamina), através da aplicação tópica na base das asas. Após a muda os insetos apresentaram aspecto ressecado, alterações morfológicas externas bastante acentuadas na cabeça, tórax, patas, asas e abdômen, dificultando suas atividades normais. Entretanto, a genitália externa de ambos os sextos mostrou-se inalterada. A aplicação da substância foi capaz de alterar e interromper o ciclo biológico destes insetos.

On Pomacea sordida (Swainson, 1823) (Prosobranchia, Ampullariidae)

A description of Pomacea sordida (Swainson, 1823) collected in Caxias and Nova Iguaçu, state of Rio de Janeiro, is presented. The shell is globose, heavy, whith greenish or horn-colored periostracum and dark spinal bands; apex subelevated, 4-5 moderately shoudered whorls, increasing rather rapidly and separated by deep suture. Aperture large, moderately round, yellowish or violaceous; lip thick and sometimes dark brown; umbilicus large and deep; operculum corneous and heavy, entirely closing the aperture. Ratios: shell width/shell length = 0.81-0.91 (mean 0.86); aperture length/shell length = 0.66-0.75 (mean 0.70). Testis, spermiduct and penis pouch as in Pomacea lineata (Spix, 1827). Seminal vesicle whitish and bean-shaped. Prostate cylindric and narrow, cream in coloar as the testis. Penis whiplike whith a closed circular spermiduct. Penial sheath elongated and tapered, with its distal tip turned to the right; outer basal gland situated on the left; inner median gland rounded; apical gland elongated and wrinkled. Ovary composed of branched whitish tubules lying superficially on the digestive gland; oviduct and seminal receptacle as in P. lineata; albumen gland yellowish - orange. Vestigial male copulatory apparatus (penis and its sheath) present in all females examined.

On Dichelyne (Cucullanellus) elongatus (Tornquist, 1931) Petter, 1974: South American correlated species (Nematoda, Cucullanidae) and some other helminths of micropogonias furnieri (Desmarest, 1823) (Pisces, Sciaenidae)

Dichelyne (Cucullanellus) elongatus (Tomquist, 1931) Petter, 1974, from Venezuela, of which D.(C.) amaurincai (Freitas, Vicente & Ibáñez, 1969) Petter, 1974 is proposed as a junior synonym, is redescribed and comments on the present status of the remaining species under the group, namely D.(C.) dichelyneformes (Szidat, 1950) Petter, 1974, D.(C.) rodriguesi (Pinto, Fábio & Noronha, 1970) Petter, 1974 and D.(C.) travassosi (Guimarães & Cristofaro, 1974), occuring in South America are made. Dollfusentis chandleri Golvan, 1969 (Acanthocephala, Illiosentidae), Poecilancistrium caryophyllum (Diesing, 1850)(Cestoidea, Otobothriidae) and Callitetrarhynchus gracilis (Rudolphi, 1819)(Cestoidea, Dasyrhynchidae) as well as larval forms of Echinocephalus sp. (Nematoda, Gnathostomatidae) and Contracaecum sp. (Nematoda, Anisakidae) are also reported.

Monogenea parasites of Micropogonias furnieri (Desmarest, 1823) (Pisces, Sciaenidae) from the littoral of Rio de Janeiro state, Brazil

From the gills of 100 Micropogonia furnieri (Desmarest, 1823) from Atlantic coast of Rio de Janeiro State, were recovered Macrovalvitrema sinaloense Caballero & Bravo-Hollis, 1955, Pterinotrematoides mexicanum Caballero & Bravo-Hollis, 1955, Rhamnocercus rhmnocercus Monaco, Wood & Mizelle, 1954 and Encotyllabe spari Yamaguti, 1934. M. furnieri represents a new host record for them and a new geographical dsitribution is referred for M. sinaloense, P. mexicanum and R. rhmnocercus.

El lloc teatral i el seu espai escènic: artialització en William Shakespeare (c..1590-1611) : actor, empresari, dramaturg

Pensar en William Shakespeare, apropar-se a una de l'obres què més tinta han fet córrer, se'ns presenta com voler trobar una agulla en un paller. Amb tot, aquest treball de recerca a volgut discernir la dramatúrgia de Shakespeare, des de l'òptica espacial i estètica. El seu marc, a l'Anglaterra renaixentista -ss,XVI-XVII-, és: l'abundosa legislació -important l'Acta promulgada l'any 1572, per la reina Elisabet I-; la tipologia constructiva i formal del Lloc del Teatre, amb la formulació empresarial què se’n deriva; l'altre element, la participació de l'espectador implícit. Conclusivament, com l'artialització shakespeariana s'insereix, podem dir, 'dramatològicament', dins l'historiografia general del teatre.

A Comparison of Two Brazilian Populations of Culex quinquefasciatus (Say, 1823) from Endemic and Non-endemic Areas to Infection with Wuchereria bancrofti (Cobbold, 1877)

Culex quinquefasciatus is known to be an efficient insect host of Wuchereria bancrofti. In Brazil Cx. quinquefasciatus is widely distributed throughout the country and is often abundant in and around human habitations. In contrast, Bancroftian filariasis is limited to three foci in Brazil. Experiments were undertaken to compare the vector capacities of Cx. quinquefasciatus originating from Maceió (Alagoas), one of the endemic areas of W. bancrofti infection in Brazil, and Belo Horizonte (Minas Gerais), a non endemic area. Laboratory-reared Cx. quinquefasciatus were dissected 20 days after blood feeding on microfilaraemic patients. Survival rates and the number of infective larvae that developed did not differ in female mosquitoes of different origins. Thus both populations of Culex were susceptible to infection with W. bancrofti

Paper money and national distress: William Huskisson and the early theories of credit, speculation and crises

This paper examines the explanation of commercial crises offered by William Huskisson in 1810 in the wake of the debate on the Bullion Report. Huskisson argued that the suspension of convertibility made it possible to extend issues of paper currency beyond its proper limits. Such an expansion, being in the interest of all parties concerned, would actually take place and stimulate excessive speculations, which would eventually prove unsustainable and bring generalized ruin and distress. Although some elements of this explanations were not new (having been anticipated by writers sucha as James Currie in 1793, William Roscoe in 1793, William Anderson in 1797 and an anonymous in 1796), Huskisson's explanation is more systematic and better organized, and his emphasis on the endogenous character of the crisis and on the instability of the dynamics of trade and credit makes it an interesting foreshadower of the theories of crises that were advanced half a century later.
