Toxicity and behavioural bioassays were used to assess the lethal and sub-lethal effects of two naphthoquinones from the Chilean plant Calceolaria andina L. (Scrophulariaceae), two products derived from Azadirachta indica and pyrethrum on the glasshouse whitefly, Trialeurodes vaporariorum Westwood, and the parasitoid Encarsia formosa Gahan. The potential use of these botanicals in an Integrated Pest Management (IPM) programme is discussed. Pyrethrum was the most toxic botanical tested, but it was toxic to both the whitefly and parasitoid. The naphthoquinones showed potential for inclusion into an IPM programme if, by formulation, the toxicity towards the whitefly could be increased and the deterrent activity towards E. formosa adults decreased. Overall, the A. indica-derived products had the most potential for use in an IPM system for the control of whitefly, which includes E. formosa as a biocontrol agent.
