گياهان ميزبان سفيد بالك ها (Homoptera: Aleyrodidae) در بعضي مناطق ايران

Host plants of whiteflies (Homoptera: Aleyrodidae) in many regions of Iran

Upon the conducted samplings through 1997-2006 in different regions of Iran including: Fars, Isfahan. Tehran, Semnan, Guilan, Mazandaran, and Golestan provinces, 214 species of host plants belong to 127 genera, and 58 families for Iranian whiteflies (Homoptera: Aleyrodidae) were Identified. The most number of whitefliesʹ host plants were determined in the families Leguminosae (21 species), Malvaceae (18 species), Solanaceae (14 species), Compositae (13 species), Rosaceae (14 species), Rutaceae (8 species), Euphorbiaceae (8 species), Oleaceae ( 8 species), and Brassicaceae (7 species), respectively. On the basis of conducted studies in different seasons, and different regions of the sampled provinces, many host plants including: Eucalyptus camaldulensis (Myrtaceae), Myrtus communis (Myrtaceae), Vitex pseudo - negundo (Verbenaceae), Malva parviflora (Malvaceae), Ziziphus lotus (Rhamnaceae) and Ricinus communis (Euphorbiaceae) were determined as important shelters for hibernation and survival of aleyrodids, because of evergreen and having the abundant foliages through year. Therefore, identification of important whitefliesʹ host plants in winter and early of spring, and planning for reduction or elimination of them from around the fields, can be accounted as fundamental process in Integrated Pest Management (IPM) of aleyrodids.
