Abstract

Five species of whiteflies (Aleyrodidae) were found on citrus in southern Texas: Aleurocanthus woglumi Ashby, Aleurothrixus floccosus (Maskell), Paraleyrodes citri Bondar, Dialeurodes citri (Ashmead), and D. citrifolii (Morgan). Parasite records for this area were Amitus hesperidum Silvestri (Platygastridae) and Prospaltella opulenta Silvestri (both Encyrtidae) attacking A. woglumi; Eretmocerus sp. near paulistus Hem. (Encyrtidae), Amitus sp., and Prospaltella sp. attacking A. floccosus; and Prospaltella sp. attacking P. citri. Predators recorded were Delphastus pusillus (Le Conte) (Coccinellidae) feeding on A. floccosus; D. pusillus and Nephaspis amnicola Wingo (Coccinellidae) feeding on P. citri. A pathogenic fungus, Aschersonia aleyrodis Webber, was found attacking D. citri.

Résumé

Cinq espèces d’aleurodes ont été relevées sur le citronnier au sud du Texas : Aleurocanthus woglumi Ashby, Aleurothrixus floccosus (Maskell), Paraleyrodes citri Bondar, Dialeurodes citri (Ashmead), et D. citrifolii (Morgan). Les parasites inventoriés furent Amitus hesperidum Silvestri (Platygasleridae) et Prospaltella opulenta Silvestri (Encyrtidae, les 2 espèces) parasitant A. woglumi; Eretmocerus sp. near paulistus Hem. (Encyrtidae), Amitus sp. et Prospaltella sp. parasitant A. floccosus; et Prospaltella sp. parasitant P. citri. Les prédateurs identifiés furent Delphastus pusillus (Le Conte) (Coccinellidae) attaquant A. floccosus; D. pusillus et Nephaspis amnicola Wingo (Coccinellidae) attaquant P. citri. Un champignon pathogène, Aschersonia aleyrodis Webber, a été identifié sur D. citri.
