Trough out one year, from march/84 to february/85, at the field conditions in Universidade Federal Rural do Rio de Janeiro and using three differents bovine coloured skin, it was studied the behaviour activity, the population changes and the physiological classification of Stomoxys calcitrans female, by the parameters keeped from laboratory conditions. It was showed that there is a diurnal variantion of the populations and an influence of the host skin color on the flies attractiveness independently of the differential weather. ged, unparous initial, unparous final, uniparous, female with two end three layings and female with more than three layings. It was recognised six classes of female: newly-emerAt the natural conditions, the female/male relationship, and parous/unparous females relationship was 1,1:1,0 and 1,6:1,0, respectively. Male and the female population have exibited similar shape during the year, but the number of activy female xxi. on the host was bigger. The femals began to mate when the oocyte was on the end of the 2nd stage and at the end of the 3rd oocitary stage it the fertilization index was 100%.

Durante um ano, de mar?o/84 a fevereiro/85, no "campus" da Universidade Federal Rural do Rio de Janeiro, e com bovinos de tr?s diferentes cores de pelagens foram estudados o comportamento alimentar, a varia??o populacional e a classifica??o de f?meas de acordo com a idade fisiol?gica de Stomoxys calcitrans, cujos par?metros foram obtidos em condi??es de laborat?rio. Constatou-se que houve varia??o diurna da atividade de popula??es e que a cor da pelagem do hospedeiro interfere na atratividade dos d?pteros independente das condi??es do tempo. O mesoclima teve pouca interfer?ncia sobre a atividade dos insetos. As classes-idade estabelecidas foram: rec?m-emergida, n?o ovipositante inicial, n?o ovipositante final, f?meas com uma postura, f?meas com duas a tr?s posturas e f?meas com mais de tr?s posturas. Na natureza a rela??o f?mea/macho e f?meas ovipositantes/f?meas n?o ovipositantes foi de 1,1:1,0 e de 1,6:1,0 respectivamente. As popula??es de machos e f?meas variam mensalmente xix. e de forma semelhante mas o n?mero de f?meas em atividade sobre os hospedeiros ? maior. As f?meas copulam a partir do per?odo oocit?rio no final do est?gio 2 e no final do est?gio 3, o ?ndice de fertiliza??o e de 100%.
