Catolaccus grandis (Burks) is an important biological control agent of Anthonomus grandis (Boheman). The objective of this work was to evaluate biological aspects of that parasitoid using A. grandis larval as host, at 26±2°C, 70±5% RH, and 12h photophase. The total life cycle of the parasitoid was 16.2 days. Incubation period lasted 1.2 days with egg viability of 100%. Larval stage showed three instars with a total duration of 7.2 days and viability of 97.2%. Duration of pupal period stage was 8.0 days, and viability 96.3%. The preovipositional period was 4.0 days; the oviposition period was 35.0 days; average number of eggs/female was 308.0; the average daily oviposition rate was 8.8 eggs/ female. Longevity of C. grandis was 51.0 days for females and 40.0 days for males.
