Starting from adults derived of Stomoxys calcitrans colony established in the 'Estação para Pesquisas parasitológicas W. O. Neitz, Universidade Federal Rural do Rio de Janeiro", under temperature of 27°C and 70-80% of relative humidity, one female and two males were isolated in individual cages to the observations of some biological parameters formely determined as number of ovipositant female, real number o eggs by female, oviposition periodicity and female longevity. After 4 repetitions with 6 fenales at the first and second, 7 and 8 females at the third and fourth repetitions, respectively, and a total of 27 isolated females, only 10 layed eggs (37.0%); the total number of layed eggs was 2,254 with a mean of 834 eggs by female; the females had a oviposition period that varied from 3 to 17 days it happening as average 10.2 days. The oviposition rhytm changed from 3 to 7 ovipositions, with intervals changing since too little 24 hours until 6 days. The females longevity were about 17 to 38 days.
