The wasp is produced commercially since the early 1970's and is one of the most widely used parasitoids. It is used mainly against whiteflies in greenhouses, i.e. the greenhouse whitefly (Trialeurodes vaporariorum), the sweet potato whitefly (Bemisia tabaci) and the silverleaf whitefly (Bemisia tabaci biotype B). The adult wasps feed on the host, but may change the host for egg laying. All nymphal and pupal stages are attacked and it may feed on around 10 1st or 2nd instars within 48 hours.
