The silver leaf whitefly,Bemisia tabaci biotype „B ”(Homoptera:Aleyrodidae)is one of the most serious vegetable and ornamental plants pest in Egypt.Predators play an important role in controlling this species. The present work deals with the abundance of indigenous predators in greenhouse on three host plants mostly of vegetable crops during April –July,1996.Chrysoperla carnea (Stephens)(Neuropteran: Chrysopidae)is considered the most abundant predator acting on Bemisia. In the meantime,the work deals also with the potential of the imported predators,namely Delphastus pusillus Le Conte (Coleoptera:Coccinellidae)and Macrophillus caliginosus (Wagner)(Hemip- tera :Miridae).These predators were released 3 times on eggplant (Solanum melongena)and at the ratio of 1 individual and 2 individuals/plant for D.pusillus and M.caliginosus,respectively.Results indicate that predators increased in numbers while whitefly population decreased in comparison to control homologues. Biotype B.tabaci was identified in John Innes Center,UK and recorded by Abd-Rabou (1999) in Egypt as first recorded for presence of this biotype.
