As taxas de intera??es na col?nia s?o reguladas pela densidade de indiv?duos que ela cont?m e atrav?s das quais pode haver rapidez na transfer?ncia de informa??o, provocando mudan?as na din?mica de rede social. A fim de analisar o fluxo de informa??o em oper?rias de Dinoponera quadriceps investigamos duas col?nias com base na quantidade de oper?rias e larvas no ninho, n?mero de intera??es individuais, n?mero de sa?das, ?for?a? e ?alcance? de cada intera??o, al?m do fluxo de informa??o em diferentes hor?rios. O estudo foi realizado no Laborat?rio de Biologia Comportamental da UFRN. Foram observadas duas col?nias com diferentes densidades de oper?rias por 16h/col?nia, totalizando 8h/dia atrav?s de grava??o com c?mera digital. As col?nias de D. quadriceps n?o apresentaram correla??o entre o n?mero total de intera??es com o n?mero total de oper?rias e nem com as sa?das do ninho. As taxas de intera??es per capita apresentaram padr?o semelhante para as duas col?nias, sendo maiores no hor?rio com disponibilidade de alimento. A col?nia com menor densidade de oper?rias apresentou mais intera??es por individuo, principalmente no dia e hor?rio com alimento, e estas intera??es obtiveram maior ?for?a? e ?alcance?. A din?mica de redes sociais tamb?m apresentou padr?o semelhante entre as col?nias, apresentando maiores fluxos de informa??o no hor?rio com alimento. Com base no exposto conclu?mos que as oper?rias de D. quadriceps regulam a atividade de forrageamento atrav?s de autoestimula??o, como tamb?m suas taxas de contato, aumentando o n?mero de intera??es em dia e hor?rio com alimento na col?nia, modificando o fluxo de informa??o e aumentando a dissemina??o da informa??o. === Social interactions between workers in a colony do not happen randomly, since workers decide how often they will interact and who they will interact with. Interactions rate in the colony are regulated by the density of individuals it contains and through which can quickly transfer information in the colony, causing changes in network dynamics. In order to analyze the flow of information among workers of Dinoponera quadriceps we investigated two colonies based on the number of workers and larvae in the nest, number of individual interactions, number of outputs, 'strength' and 'reach of each interaction, and also the information flow at different times. The study was conducted in the Behavioral Biology Laboratory at UFRN. Two colonies with different densities of workers were observed for 16h/colony, totaling 8 hours/day by recording using a digital camera. Colonies of D. quadriceps showed no correlation between the total number of interactions with the total number of workers nor to the number of nest exits. The per capita rates of interactions showed a similar pattern in both colonies, being higher during the food availability periods. The colony with lower density of workers had more interactions per individual, especially on the day and period with food, and these interactions got stronger and greater range. The dynamics of social networks also showed a similar pattern among colonies, with greater flow of information during the feeding time. Based on these results we conclude that workers of D. quadriceps regulate foraging activity through self-stimulation, as well as with their contact rates by increasing the number of interactions when food was offered to the colony, changing the flow of information and increasing dissemination of information.
