It was first introduced to the U.S. during the early 1970’s and released in experimental fields in Mississippi State, MS (Johnson et al. 1973). Researchers observed encouragingly high parasitism rates, but failure of this parasitoid to become established made it unsuitable for use within a classical biological control program. It was reintroduced a decade later and released in College Station, TX (Cate et al. 1990). Rearing methods for this parasitoid progressed quickly between 1985 and 1992 making C. grandis suitable to be used in a biological control by augmentation program (Cate 1987, Morales-Ramos et al. 1994).
