This study aimed at observing the number of foundations and abandonments in colonies of Mischocyttarus cearensis, as well as verifying the influence of weather-related factors (temperature, relative humidity and rainfall) on these activities. The observations were carried out from November 2001 through November 2003 on the Campus of Universidade Estadual de Feira de Santana, in the city of Feira de Santana, BA (12 degrees 58’LS; 38 degrees 57’LW Gr). The total number of foundations of M cearensis registered was 433. The main reason for deserting was simple or natural causes (57%). There was no significant influence of the physical factors of weather studied on the number of foundations and abandonments. The colonies of M. cearensis presented an average longevity of 18-83 weeks ( +/- 14.7).
