Technical Abstract: A biological control program was initiated to develop and implement strategies to manage Diaprepes abbreviatus (L.) in response to the spread of this weevil in Florida and the latest infestations in Texas and California. This classical biological control effort is collaborative, involving state, federal, private institutions and international cooperators in foreign exploration, quarantine, mass production, release, and recovery efforts. A lack of native parasitoids attacking this weevil in Florida and past failures to establish exotic parasitoids against it motivated these new efforts to introduce, release and evaluate candidate egg parasitoids. The parasitoids released were, Ceratogramma etiennei (Delvare) (Hymenoptera: Trichogrammatidae), Quadrastichus haitiensis (Gahan) and Aprostocetus vaquitarum (Wolcott) (Hymenoptera: Eulophidae). Here we summarize parasitoids tested in quarantine, recoveries, and relative abundance of parasitoids from release sites in citrus, ornamentals and natural plant habitats.
