A field survey was conducted on the reproductive host plant species of the Bemisia tabaci (Gennadius) complex throughout Egypt. Infested plants were collected during each month of the year. Bemisia tabaci completed its development on 118 species of plants in 79 genera belonging to 28 families. The family Asteraceae (= Compositae) included 23 host plant species (20% of the total) belonging to 16 genera, while the family Fabaceae (= Leguminosae) included 17 host plant species belonging to 13 genera. The study revealed six new reproductive host plants consisting of five species and one subspecies in the families Asteraceae, Fabaceae, Piperaceae, Plantaginaceae and Portulacaceae. About 70% of the host plants are new host records for Egypt. Several recent studies have mistakenly cited a previous list of B. tabaci hosts in Egypt by erroneously referring to an early world host list as being a list of hosts in Egypt. The results of this study have implications on whitefly ecology and management.
