Schematic diagram describing how inoculation of citrus plants with engineered triple gene construct (CTV-tAwd-tWnt-tPDS) could be deployed to attract and kill D. citri. (I)  PDS silencing results in enhanced olfactory (VOCs), visual (photobleached phenotype), and gustatory (phloem sap chemical composition and leaf metabolites) cues that attract D. citri. (II) After the insect vector feeds on CTV-tAwd-tWnt-tPDS-inoculated plants, RNAi-induced silencing of both abnormal wing disc (Awd) and wingless (Wnt) expression kills vectors or otherwise impairs the ability to transmit pathogen.
