The life expectancy of Sarconesia chlorogaster (Wiedemann, 1830) reared in artificial diet and controlled temperatures chamber set at 27±1oC, 70±10% RH and 12 hours of photophase was analysed using entropy (H). Entropy (H) was used to quantify the distribuition of deaths between ages and then quantify the impact of mortality on life expectancy. The entropy values obtained for males (H=0,245) and females (H=0,299) were intermediary between the theoretical values of H=0,5 and H=0 suggesting a tendency toward rectangular distribuitions in both sexes. The effect of mortality across ali ages on expectation of life was different at each age. For males the highest values were found between days 10 and 20 and between days 15 and 25 for females. This íindings imply that small changes in female mortality will have a greater impact on female life expectancy than will have on male expectation of life.

The activities were performed at a preserved forest named "Capão da Imbuia", in the urban area of Curitiba, Paraná, Brazil, during march/1990 till march march/1991. The tree holes studied, showed different features: soil distance, area and volume. 303 immatures forms from seven specie of Culicidae were caught: Haemagogus (Conopostegus) leucocelaenus (Dyar & Shannon, 1924), Culex (Culex) acharistus Root, 1927, Toxorhynchites (Lynchiella) theobaldi (Dyar & Knab, 1906), Culex (Culex) eduardoi Casal & Garcia, 1968, Culex (Culex) quinque-fasciatus Say, 1823, Aedes (Protomacleaya) terrens (Walker, 1856). Two species were the most frequent: Haemagogus (C.) leucocelaenus and Toxorhynchites (L.) theobaldi, both of them had the higlest medias during spring and summer. These species were in overposition during the caughts.

In this study carried out in the Caetetus Ecological Station, Sao Paulo, southeastern Brazil, a wild group of black lion tamarins was accompanied during 1989 to 1991, to analyse the dietary habits of the species. The scan sampling method was used to gather data. A total of 961 behaviors were recorded, of which feeding occupied 23.3% of the time involved in the behaviors. The major dietary components observed in the black lion tamarins were fruits, tree exudates and animal preys (67.9%, 22.8% and 8.9% respectively). Fruits varied monthly from 47.4 to 97.1 %, being consumed more during the rainy season, while tree exudates varied from 0 to 54.7%, and were consumed mainly during the dry season. The animal prey accounted for 0 to 15.8% of the diet. The most important dietary resource for the black lion tamarins was the fruit of Syagrus romanzoffiana Glass., representing 29.9% of the foraging observations. The diet exhibited pronounced differences among dry and rainy seasons, presumably as a consequence of the food shortage of fruits during dry season.

Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred between 25 and 50 days. The females fertilized only once produced one or more broods, each brood varying from 10 to 30 youngs. The spermatic mass reserved in the seminal receptacle depleted after having realized one, two or, rarely, three broods; the females without sperm in the receptacle realized ecdise, lost oostegites and got again virginal aspect. Females in such condition, kept alone, isolated from males have never acquire oostegites again. Otherwise, in contact with males, once fertilized they realized ecdise and acquired new oostegites. The authors have concluded that the oostegites only are formed because of the received sperm and its continuity depends on the sperm accumulated in the seminal receptacle, for more than one brood.
