Systematic Entomology Laboratory, IIBIII, Ag-ricultural Research Service, USDA, Beltsville, Maryland 20705; (JE)' Entomol-ogist, Institut de Recherches-Agronomiques Tropicales, 97487 Saint-Denis, La Reunion, France. /Ifo/rac/.— Collection data are given for 1 5 described and five undescribed species of Aleyrodidae and for six collections of early stage Aleyrodinae. Citations are given to 2 1 publications that contain references to the Aleyrodidae of Reunion. Parasites and/or predators of four species of Aleyrodidae are indicated. This list of the Aleyrodidae of the Island of Reunion is the first to be published on the aleyrodid fauna of a Mascarene Island. The article lists 2 1 species of Aleyrodidae, six of which apparently are undescribed, and six collections of un-identified larvae, with collection data. The species belong in the Aleyrodinae except for one, indicated in the list, which is placed in the Aleurodicinae. Parasites and/or predators of four aleyrodid species are listed. The collections were made by J. Etienne except as noted, and the specimens are in the U.S. National Museum of Natural History, Washington, D.C. The aleyrodids are reported from 3 1 plant genera belonging to 20 families and from several unidentified plants. Eleven genera and seven families are recorded, for the first time, as hosts of Aleyrodidae in Reunion. The botanical names appearing herein have been checked in Hortus Third (Staff of the L. H. Bailey Hortorium, Cornell University. 1976) and/or Index Kewensis and Supplements (various compilers, 1855-1974). Family names of plants are given only once, the first time a host plant is listed. Literature citations are given for all the articles we have found that have scientific names of Aleyrodidae reported from Reunion. Aleyrodidae of Reunion Acutaleyrodes palmae Takahashi.
