Detailed biology of the parasitoid Eucelatoria bryani Sabrosky was studied under laboratory condition. The incubation period and duration of first, second and third instars were 138 ± 2.02, 29.93 ± 2.01, 33.67 ± 1.95 and 36.87 ± 2.47 respectively. The pre-pupal and pupal periods were 5.40 ± 1.18 and 6.93 ± 0.96 days, respectively. Total life cycle occupied 23.89 ± 1.04 days. Food influenced the fecundity and longevity of the parasitoid.
