• Brood guarding behavior and life history characteristics of Goniozus indicus Ashmead (Hymenoptera : Bethylidae) were examined in the laboratory. Longevity was increased when females were provided host frass, and females reared in association with hosts lived longer than females maintained separately from hosts. Females that were allowed free access to hosts oviposited at intervals of one to eight days and never parasitized more than one host per day. Females laid 5-25 eggs per host, and life time fecundity was 15-52 eggs at 25℃, 7-60 eggs at 28℃, and 5-25 eggs at 31℃. Females exhibited egg guarding behavior, remaining with the hosts after parasitization. Although the guarding period varied, the majority of females left the host before or during eclosion of their eggs. Considered together with the difficulty of finding and successfully parasitizing suitable hosts, brood guarding behavior appears to increase reproductive success of G. indicus.
