Arthropod parasitoids and predators are ubiquitous and operate continuously on all life stages of the whitefly, functioning as control factors in the process. The goal of biological control is to better exploit this behavior in order to more effectively manage pests and reduce insecticide use. Biological control of whiteflies and other pests has been pursued through observation and utilization of natural enemy activity (e.g., Albajes et al. 2003), through search for and introduction of natural enemies (e.g., Gould et al. 2008; Nomikou et al.
