The Lucilia cuprina laboratory breeding depends, fundamentally, on reproductive behavior and longevity information. In the present study it was verified that, due to the species isolation, there was a remarkable increase in the number of eggs/female (1344.18), when compared to the number of grouped eggs/female (732.78). The eggs viability was reduced due to the isolation of L. cuprina female. The longevity rate was estimated in 29.41 and 31.20 days for grouped males and females, respectively. For isolated males and females the longevity rate was 25.20 and 33.89, respectively.
