    Description / Table of Contents: Résumé De novembre 1976 à octobre 1979, on a échantillonné mensuellement dans les zones urbaines du Comté de Broward, Floride, les populations de la mouche noire des citrus,Aleurocanthus woglumi Ashby et de ses parasites. Pendant cette période les parasites,Amitus hesperidum Silvestri etProspaltella opulenta Silvestri se sont établis et ont limité les populations deA. woglumi. Une succession dans les parasites a été notée:A. hesperidum fut abondant d'abord et remplacé ensuite en fréquence parP. opulenta. Les 2 espèces ont continué à coexister et causent la mortalité des faibles populations du ravageur malgré les traitements chimiques utilisés pour l'éradication; ce qui montre la possibilité d'une lutte intégrée contreA. woglumi maintenant que ce ravageur est bien établi en Floride.
    Notes: Abstract From November, 1976 until October, 1979 citrus blackfly,Aleurocanthus woglumi Ashby and its parasite populations were sampled monthly in urban areas of Broward County, Florida. During this period, the parasites,Amitus hesperidum Silvestri andProspaltella opulenta Silvestri became established and exerted control onA. woglumi populations. Parasite succession was noted in thatA. hesperidum was first abundant and later replaced in abundance byP. opulenta. The 2 parasite species continued to coexist and exert mortality on low pest populations in spite of chemical spraying used for eradication showing that integrated control ofA. woglumi is a definite possibility now that the pest is well established in Florida.
