Abstract in English:Attrativeness of differents baits (fish, faeces and banana) upon ovarian development fases of Calliphoridae and Sarcophagidae was evaluated. The insects were captured in Distrito Federal (urban area) and Rio de Janeiro city (beach, zoological garden, urban area and Tijuca forest). The most frequent species captured were: Calliphoridae - Chrysomya megacephala (Fabricius, 1794) 78,9% and Chtysomya puloria (Wiedemann, 1818) 5,4% - and Sarcophagidae - Sarcophagula Wulp, 1887 2,3% and Peckya chrysostoma (Wiedemann. 1830) 2,2%. Fish was more attractive to females of Calliphoridae flies in intense ovarian vitelogenesis, although banana atracted more flies with mature eggs. Faeces and fish were more atractive for Sarcophagidae in the beggining of vitelogenesis.
Abstract in English:Great part of lhe avaiable data about snakes reprodution refers to species coming from subtropical and temperate regions. In Brazil, the data is rather rare and can be found in various works where information is restricted. Results from studies developed with five viviparous snakes - Crotalus durissus cascavella (Wagler, 1824). Bothrops erythromelas(Amaral, 1923), B. leucurus (Wagler, 1824), Helicops leopardinus (Schlegel, 1873) and Thamnodynastes strigilis (Thiinberg, 1787) - which come from the Northeast of Brazil (Bahia) are described. Data about pregnancy and birth, number, sex ratio, length and weight of neonates is given and discussed.

Abstract in English:Two Malaise traps (TOWNES 1972 model) were installed on an island (the "Ilha do Mel") in the Bay of Paranaguá, from September, 1988 to August, 1989. at two sites denominated "Fortaleza" and "Praia Grande", for collection of insects. Apart from collection of insects (Fortaleza: 62.924 individuals; Praia Grande: 38.868 individuais), graphical analysis were limited to those Orders wich occurred concomitantly at the two collection points in ali months: Collembola. Hemiptera. Homoptera. Coleoptera. Lepidoptera. Diptera and Hymenoptera. It was concluded that the Malaise trap is selective for Diptera. Hymenoptera and Lepidoptera. and proved to be efficient in measuring abundance, in obtaining information regarding the seasonal variation of insects, and in comparing the entomofauna of different geographical localities.
Abstract in English:Two Malaise traps (TOWNES' 1972 model) were installed on an island (lhe "Ilha do Mel") in lhe Bay of Paranaguá, from September, 1988 to August. 1989. at two sites denominated "Fortaleza" and "Praia Grande", for colleetion of insects. At "Fortaleza". 1,715 individuais of Tabanidae were captured, representing 3.20% of all Diptera captured in this site, while at "Praia Grande" 1,420 individuais of the same family were captured, representing 5,06% of ali Diptera captured there. In "Fortaleza", Tabanidae is represented for 10 species, while in "Praia Grande" it is represented for nine species. Dichelacera alcicomis (Wiedemann. 1828) was the most abundant species at two sites, representing 87,52% and 66,69 % of all Tabanidae captured at "Fortaleza" and "Praia Grande", respectively. The grealest number of individuais occurred in November, the month with the lowest relative humidity associated to small pluviometric precipitation, just after a month with high relative humidity associated to a high pluviometric precipilation.

Abstract in English:The aim of lhe presenl work is to descrihe the biological cycle of the Apiomenis lanipes (Fabricius, 1803) (Hemiptera, Reduviidae) on lahoralory conditions. Adults of Drosophila sp. (Diptera, Drosophilidae) and Ceralitis capitula (Wiedemann, 1824) (Diptera. Tephritidae) was offered for hug feeding (nymphs and adults). The developmenlal of the entire cycle (egg to adult) was 288.26 days and 294.85 days for males and females, respectively.

Abstract in English:The time of full stomach repletion and fat condition was determined through an analysis of the average stomach repletion index, condition faclor and relative frequency of repletion for different periods of the year. Condition factor was influenced by weight gain in the stomaches, main from April to June.
Abstract in English:This species showed feeding activily ali year long. Although zooplancton, protozooplancton and other organisms have been found in the stomaches, this species can be considered, broadly speaking, herbivorous since a great amount of seaweed was found in its diet. Fulness of the stomachs was not associated with sex difference. Full stomachs were found throughout the period. Variations according to the estimated periods were not found.

Abstract in English:A new technique to reliably estimate true tadpole abundance in small ephemeral forest ponds based on a sample taken from a bottom net is presented. The bottom net is placed in the pond before it fills with water. At given intervals the bottom net is lifted through the water column and all tadpoles can be counted. Based on a series of calibrations, the technique showed significant correlations between estimated abundance of Osteocephalus taurinus Steindachner, 1862, Colostelhus marchesianus Melin, 1941, Phyllomedusa tomoptema Cope, 1868, and aeshnid larvae, and true abundances based on total counts.
