Strawberry whitefly: Trialeurodes Packardi

Populations of iris whiteflies and, to a lesser extent, strawberry whiteflies have always been present in low numbers in strawberry fields in California. These species are usually kept below damaging levels by naturally occurring beneficial insects. In recent years, however, a third species, the greenhouse whitefly, has become a major pest in certain areas on the Central Coast and in southern California. The greenhouse whitefly has a large host range including alfalfa, avocados, beans, blackberries and other berries, cucumbers, eggplants, grapes, lettuce, melons, peas, peppers, potatoes, tomatoes, and many ornamentals, and these alternate hosts serve as sources for whiteflies that enter strawberry fields.
