Biomphalaria tenagophila (Orbigny, 1835) (Mollusca): adaptation to desiccation and susceptibility to infection with Schistosoma mansoni Sambon, 1907

Experiments were carried out to test the susceptibility of Biomphalaria tenagophila to the infection with strain SJ of Schistosoma mansoni in the F1, F2 and non-selected parental generation. The potential adaptation of B. tenagophila to desiccation, in healthy mollusks and those exposed to the larvae of S. mansoni of the F1, F2 and non-selected parental generations was also studied. The presence of mucus and soil, at the shell opening, protected the snails against desiccation, favoring survival. The healthy mollusks performed more attempts against desiccation than those exposed to the larvae of the parasite. The mortality rate, during desiccation, was higher among mollusks that remained buried and with the shell opening unobstructed. During the desiccation period the stage of development of the parasite was influenced by the weight loss and the survival of the snails. The longer the period of desiccation, the greater was the weight loss observed, abbreviating survival. The non-selected parental generation was more sensitive to desiccation than the F1 and F2 generations, both in healthy mollusks and in those exposed to S. mansoni larvae. Healthy mollusks were more resistant to desiccation than those exposed to the larvae of the S. mansoni. Desiccation did not interrupt the development of S. mansoni larvae in mollusks, causing a delay in the cercariae elimination. The susceptibility of B. tenagophila to the SJ strain of S. mansoni, in mollusks maintained in water during the larvae incubation period, was similar in all three generations.

The effects of the experimental infection from a focus of transmission of Schistosoma mansoni in a population of Biomphalaria tenagophila (D'Orbigny, 1835) in the region of "Vale do Ribeira de Iguape", Brazil

To observe the effects of the parasitic infection on the biology of B. tenagophila, field and laboratory populations of this mollusk from Itariri, in Vale do Ribeira, Brazil, were experimentally infected. Each mollusk received 10 miracidia of Schistosoma mansoni (SJ lineage) and was observed throughout the parasite's development. The biological variables were compared according to the criteria "group" and "infectious phase". The main damage caused by the parasitic infection manifested itself in reproduction, longevity and lesions on the shell of the mollusks in the patent phase. An infection rate of 58.8% was observed. Microanatomical study of the mollusk's digestive gland and ovotestis revealed the presence of evolving larval forms and cercariae. It was concluded that the effects of the parasitic infection on both populations were moderate, despite the low survival rate of the infected mollusks, the damage did not prevent either reproduction or the elimination of cercariae, which continued for a long time.

FIRST CASE OF HUMAN INFECTION BY Bertiella studeri (Blanchard, 1891) Stunkard,1940 (Cestoda; Anoplocephalidae) IN BRAZIL

SUMMARY Cestodes of the Bertiella genus are parasites of non-human primates found in Africa, Asia, Oceania and the Americas. Species Bertiella studeri and Bertiella mucronatacould, accidentally, infect human beings. The infection occurs from ingestion of mites from the Oribatida order containing cysticercoid larvae of the parasite. The objective of this report is to register the first case of human infection by Bertiella studeri in Brazil. Proglottids of the parasite, found in the stool sample of a two-and-a-half-year-old child, were fixed, stained and microscopically observed to evaluate its morphological characteristics. Eggs obtained from the proglottids were also studied. The gravid proglottids examined matched the description of the genus Bertiella. The eggs presented a round shape, with the average diameter of 43.7 µm, clearly showing the typical pyriform apparatus of B. studeri. The authors concluded that the child was infected with Bertiella studeri,based on Stunkard's (1940) description of the species. This is the fifth case of human Bertiellosis described in Brazil through morphometric analysis of the parasite, the third in Minas Gerais State and the first diagnosed case of Bertiella studeriin Brazil.

Comparação da capacidade ovipositora de Biomphalaria glabrata (Say, 1818), Biomphalaria tenagophila (D'Orbigni, 1835) e Biomphalaria straminea (Dunker, 1848), mantidas em laboratório

O autor comparou a capacidade ovipositora de 3 espécies de Planorbidae, Biomphalaria glabrata, B. tenagophila e B. straminea, durante um período de 30 dias, compreendidos entre os meses de Março e Abril de 1978. Registrou-se diariamente o número de ovos e desovas, referentes a 20 exemplares de cada espécie em questão. A análise estatística dos dados obtidos revelou que os exemplares de B. glabrata apresentaram maior capacidade ovipositora que as outras duas espécies em questão. A menor capacidade ovipositora foi atribuída à espécie B. tenagophila.

Triatoma rubrovaria (Blanchard 1843): tábua de vida das ninfas, duração das formas e oviposição das fêmeas

Os autores acompanharam a evolução de 150 ovos de Triatoma rubrovaria o que permitiu a construção de uma tábua de sobrevida das ninfas. A forma alada foi atingida por 94,64% dos exemplares, sendo 79 deles machos e 65 fêmeas. O tempo médio dos alados machos foi de 115 dias e das fêmeas, 99 dias. Parte desses exemplares formaram 30 casais, mantidos isolados, o que possibilitou o levantamento da postura de cada fêmea. Outro lote, também formado por 30 machos e 30 fêmeas, foi mantido em um único cristalizador de vidro, o que permitiu constatar sua maior postura (7.832 ovos) em relação aquela das fêmeas acasaladas por único macho (5.167). O bom desenvolvimento dos exemplares no processo de evolução e de reprodução da espécie, nas condições do experimento, mostrou a boa capacidade de manutenção das colônias do Triatoma rubrovaria, em condições de laboratório.

Distribuição das espécies do gênero Loxosceles Heinecken & Lowe, 1835 (Araneae; Sicariidae) no Estado do Paraná

O Estado do Paraná registra anualmente uma média de 2.577 acidentes loxoscélicos por ano, logo o conhecimento da distribuição das espécies do gênero Loxosceles é extremamente importante para elaboração de ações de controle e manejo. Realizou-se o mapeamento das Loxosceles tombadas em diferentes coleções científicas. Foram registradas 1.561 aranhas, identificadas como Loxosceles intermedia (67%), Loxosceles gaucho (19,5%), Loxosceles laeta (10,8%) e Loxosceles hirsuta (2,4%), provenientes de 20 regionais de saúde e 69 municípios. Loxosceles intermedia ocorreu em todas as regiões do estado (50 municípios), enquanto Loxosceles gaucho ocorreu no norte e noroeste, (17 municípios), Loxosceles laeta no sul (13 municípios) e Loxosceles hirsuta nas regiões oeste e centro (10 municípios). No Paraná ocorrem quatro das oito espécies de Loxosceles registradas no Brasil. Estudos nos locais de incidência e levantamentos em áreas ainda não amostradas devem ser realizados, devido à importância médica que os acidentes causados por essas aranhas têm produzido.

Life cycle and reproductive patterns of Triatoma rubrovaria (Blanchard, 1843) (Hemiptera: Reduviidae) under constant and fluctuating conditions of temperature and humidity

The aim of this study was to evaluate the temperature and relative humidity influence in the life cycle, mortality and fecundity patterns of Triatoma rubrovaria. Four cohorts with 60 recently laid eggs each were conformed. The cohorts were divided into two groups. In the controlled conditions group insects were maintained in a dark climatic chamber under constant temperature and humidity, whereas triatomines of the ambiental temperature group were maintained at room temperature. Average incubation time was 15.6 days in the controlled conditions group and 19.1 days in the ambiental temperature. In group controlled conditions the time from egg to adult development lasted 10 months while group ambiental temperature took four months longer. Egg eclosion rate was 99.1% and 98.3% in controlled conditions and ambiental temperature, respectively. Total nymphal mortality in controlled conditions was 52.6% whereas in ambiental temperature was 51.8%. Mean number of eggs/female was 817.6 controlled conditions and 837.1 ambiental temperature. Fluctuating temperature and humidity promoted changes in the life cycle duration and in the reproductive performance of this species, although not in the species mortality.

Densidade de oviposição, e quantificação de Larvas e Pupas de Mansonia Blanchard, 1901 (Diptera: Culicidae), em Eichhornia crassipes Solms. e Pistia stratiotes Linn. Na ilha da Marchantaria, Amazônia Central

A população de imaturos de Mansonia em águas brancas da várzea da ilha da Marchantaria, na Amazônia Central se constituiu de 74% de Mansonia (M.) humeralis Dyar & Knab, 1916, 14% de Mansonia (M.) titillans (Walker, 1848) e 12% de Mansonia (M.) amazonensis Theobald, 1901, como foi indicado pela frequência, medida por oviposição (posturas). O número de posturas de M. humeralis e M. titillans foi maior em Pistia stratiotes Linn. enquanto que M. amazonensis foi mais abundante em Eichhornia crassipes Solms. O número total de larvas e pupas de Mansonia spp. foi de 6997 e 570 respectivamente, sendo maior em E. crassipes (4372 e 328) que em P. stratiotes (2625 e 242). Ao longo do ano, o maior número de larvas e pupas foi encontrado nos meses da vazante (agosto-outubro), tendo um pico no mês de agosto, que não foi correlacionado significativamente com os fatores abióticos.
