Padrão reprodutivo de Elachistocleis bicolor (Anura, Microhylidae) na Serra da Bodoquena, Mato Grosso do Sul, Brasil

The reproductive pattern of Elachistocleis bicolor (Guérin Méneville, 1838) was studied at Serra da Bodoquena, from October 2000 to September 2001. Reproduction occurred in the wet season (October to April) and was correlated to high continuous pluviometric precipitation. The species presents sexual size dimorphism, with females larger than males. The number of mature eggs per ovary was 620 ± 251 (n=39) and mature eggs measured 1.15 ± 0.30 mm (n=40). Elachistocleis bicolor presented significant relations between snout-vent length and number of mature eggs (n=39; r²=0.25; p=0.001), individual weight and number of mature eggs (n=41, r²=0.30; p=0.002), snout-vent length and ovarian weight (n=35; r²=0.47; p<0.01), and individual weight and ovarian weight (n=36; r²=0.55; p<0.01). Weight and volume are better to study size-fecundity relationships than snout-vent length. The females invested 22.7 ± 6.3 % (n=35) of their weights in reproduction and the variance associated to this variable was high, related to the reproductive mode of the species.

Larva and pupa of Metaxycera purpurata (Chrysomelidae, Cassidinae, Chalepini)

Larva and pupa of Metaxycera purpurata (Guérin-Méneville, 1844), collected on Cecropia (Cecropiaceae), are described and illustrated. They are the first immature forms described to this genus.

Dinâmica de populações de Euglossina (Hymenoptera, Apidae) em mata ciliar, Urbano Santos, Maranhão, Brasil

Machos de Euglossina foram coletados por meio de iscas-odores de benzoato de benzila, eucaliptol, eugenol, salicilato de metila, vanilina, durante um ano em área de mata ciliar, no município de Urbano Santos, Maranhão. As coletas foram realizadas mensalmente, entre 8 h e 16 h, totalizando 96 horas de amostragem. Foram amostrados 283 indivíduos, 4 gêneros e 16 espécies. Euglossa Latreille, 1802 foi o gênero mais abundante, seguido por Eufriesea Cockerell, 1909, Eulaema Lepeletier, 1841 e Exaerete Hoffmannsegg, 1817. As espécies mais freqüentes foram Euglossa modestior (Dressler, 1982), Euglossa cordata (Linnaeus, 1758), Eulaema cingulata (Fabricius, 1804), Exaerete smaragdina (Guérin-Menéville, 1845), Eulaema nigrita Lepeletier, 1841 e Euglossa gaianii Dressler, 1982. Eucaliptol foi a essência mais atrativa. As maiores freqüências de visitas ocorreram no período da manhã e a maior diversidade de espécies ocorreu no período chuvoso.

Coraliomela brunnea brunnea: morfologia do adulto e sinonímias (Coleoptera, Chrysomelidae)

O adulto de Coraliomela brunnea brunnea (Thunberg, 1821) é redescrito e ilustrado incluindo novos caracteres morfológicos. Coraliomela brunnea collaris (Guérin-Méneville, 1840) e C. brunnea nigripes (Guérin-Méneville, 1840) são considerados sinônimos de C. brunnea brunnea.

Protozoários intestinais de vertebrados observados em Salobra

Protozoa were collected by means of dry smears and cultures in Cleveland's medium contained in 2cm3 ampules. The isolation and subsequent cultivation of trichomonad organisms in ampules were generally successfull; but the cultures went down, when transferred to test-tubes in the same medium, apparently because of the liberation of characteristic pigment by Bacillus pyocyaneus.

Poderá o carrapato transmitir a lepra?: isolamento e cultura dum bacilo acido-álcool resistente de sedimento de "Amblyomma cajennense" capturado em leproso: 2ª nota

In this 2nd note upon the possibility of transmission of human leprosy by ticks, the A. relates his stepps to obtain the collaboration of his colleagues working in leprosaria in various States of Brazil, Argentina and Paraguay in such studies. Firstly the A. describes the positive results of examination of sediment of ticks, the cattle tick Boophilus microplus (Canestrini, 1888), received from Paraná (Leprosário São Roque) , which were put on active lepers, two of them sucking during 9 days and one during 7 days. Two out of three were killed for examination and were very strongly positive for acid-fast bacilli. A series of tubes of Loewenstein medium was smeared with the sediment of such ticks. Secondly the A. relates his personnal experiment, carried out in Rio de Janeiro, trying to infect normal ticks in lepers. The experiment with Boophilus microplus was negative and was twicely positive the experiment with Amblyomma cajennense Fabricius, 1794. The experiment is being in progress and will be continued in other places of Brazil. Finally, after being given the general characteristics of Boophilus microplus, the A. describes the non-chromogenic culture of a acid-fast bacillus isolated by him from sediment of ticks (Amblyomma cajennense) captured in lepers from Colônia Santa Isabel (Minas gerais), which parasitism was spontaneous. The first isolation was obtained in Loewenstein medium after 62 days incubation at 37°C. The culture is pure and the bacillus is permanent acid-fast. The plate1, in full color, represents this culture in its four generations. The colonies are pearl-white in color, dry, elevated and rough, developing slowly and beginning as white pinhead points scattered upon the surface of the medium. The culture is not yet rich enough to be inoculated into laboratory animals, which will be done when possible.
