Although the Greenhouse Whitefly (GWF), Trialeurodes vaporariorum has a lot of host plants, it still dislike having some plants. Those plants, which T. vaporariorum hates eating may control T. vaporariorum populations dramatically. This paper describes a laboratory study aimed at assessing the potential of plant juice for use as commercial insecticides. Insecticidal activity of 4 plant juices was assessed against each developmental stage (eggs and larva) of T. vaporariorum. Spraying plant juices reduced eggs more than 65%, so T. vaporariorum will be controlled significantly by various concentrations of plant juice. It will be a promising future to use secondary plant metabolites to control T. vaporariorum.
