Popis:	Citrus blackfly (CBF), Aleurocanthus woglumi Ashby, was discovered in Fort Lauderdale, Fla., in 1976. Parasites Encarsia opulenta (Silvestri) (Hymenoptera: Aphelinidae) and Amitus hesperidum Silvestri (Hymenoptera: Platygasteridae) were released in infested areas. CBF populations declined and control is now mainly due to the k-selected parasite E. opulenta . On Merritt Island, however, a third parasite, now known to be a facultative hyperparasite on E. opulenta , was released: Encarsia smithi (Silvestri). Parasite and CBF populations were monitored on Merritt Island from 1981 to 1984. The three parasite species progressed through an initial dominance by A. hesperidum , to intermediate dominance by E. smithi , to final dominance by E. opulenta .
