Abstract: The importance of the agricultural system in creating high densities of Bemisia tabaci populations can not be underestimated. The types and sequence of crops grown in the Imperial and southern San Joaquin valleys provide a constant source of food for whitefly populations. In these valleys, alfalfa, cotton, cole crops and melons are grown in vast acreages and in sequences that serve as major sources of whiteflies. Due to the overlapping harvesting of a number of crop hosts, perpetually high numbers of whiteflies disperse from one crop host to another. Whitefly movement from May through November resulted in a heavy reliance upon insecticides, which may continue to be necessary for crop protection. Management of building whitefly populations led to creation of several regional programs in Arizona and California. These programs varied in their approaches, but resulted in reduced and created manageable whitefly populations in their respective agricultural systems. Management and reduction of B. tabaci populations in California resulted from various changes in the agricultural system. These include the use of the neonicotinoid, imidacloprid; use of insect growth regulators, buprofezin and pyriproxyfen; implementation of management decisions; monitoring for insecticide resistance; short season and reduction of cotton acreage; shortening of alfalfa harvesting cycles, and cropping pattern changes. In general, all the aforementioned factors impact B. tabaci population densities, with some are being more important than others.
