Whitefly-transmitted disease agents cause significant losses throughout the world. Although not considered as important as aphids on a worldwide basis, they are responsible for the natural spread of a large number of economically important diseases in the tropical and subtropical areas. Recent years have shown an increase in losses in wide areas north and south of the tropics, approaching areas of intensive agricultural production such as the southern United States, Jordan, and Israel (26, 28, 32, 43). These areas are in the apparently increasing range of Bemisia tabaci (Gennadius), the most intensively studied whitefly vector. Recent years have shown, if not an absolute increase, at least an increase in the awareness of disease losses caused by two other whitefly species, Trialeurodes vaporarium (Westwood) and T. abutilonea (Hald.), in temperate areas of the United States, Europe, Australasia, and Asia (41, 42, 58, 60, 86, 102).
