The parasitoid Aprostocetus vaquitarum was collected in Dominican Republic and introduced into the USA in 2000, and released during 2001 in southern Florida in citrus and ornamental plantings for the biological control of the Diaprepes root weevil,Diaprepes abbreviatuseggs. A. vaquitarumis a gregarious ectoparasitoid, depositing 2-48 eggs per egg mass of D.abbreviatus(n=7-91 eggs/egg mass). The larvae of the parasitoid, 'preys' upon the host eggs causing 60-100% mortality to D. abbreviatus eggs. A. vaquitarum has become established since the year of its release in southern Florida. Parasitoid dispersion has been observed within a 4 mile ratio from the nearest release site.
