none A simple method was developed to collect large numbers of the egg-larval parasite, B. oophilus Fullaway for inoculative and inundative releases to enhance biological control of tephritid fruit flies. Whole papaya fruits, Carica sp., infested in the laboratory by the oriental fruit fly, Dacus dorsalis Hendel, were exposed to the parasite in the field. The flies and parasites in the fruits were reared through to adults in the laboratory. The simplicity of the method required only the labor of one person to collect large numbers of B. oophilus of uniform age. In addition, the method can be used as a survey tool to collect other species of parasites and to determine spatial and seasonal distribution in the field.
