Two phytoseiid species, Euseius scutalis (Athias-Henriot) and Typhlodromips swirskii (Athias-Henriot), are able to suppress whitefly populations on single plants and are candidate biological control agents for whiteflies such as Bemisia tabaci (Gennadius). These species can feed on pollen and insect-produced honeydew and these food sources are likely to be available in crops. If the utilization of these food types results in increased reproduction or survival, populations of predators can persist when whitefly prey is scarce or absent. We studied the impact of pollen and whitefly-produced honeydew on the life history of the two phytoseiids. Cattail pollen allowed for survival, development and reproduction of both predators. Whitefly-produced honeydew greatly increased survival of E. scutalis, allowed for development into adulthood and for a sustained low rate of oviposition. The survival of adult T. swirskii was high on cucumber leaf tissue, either with or without pollen or honeydew. Oviposition by adults and juvenile survival of T. swirskii was very low in presence of honeydew. Biological control of whiteflies may benefit from both pollen and honeydew because these non-prey food sources have a positive effect on the life history of the two predator species, especially E. scutalis.
