Compositions and methods for deterring feeding by psyllids

The invention relates to a plant that includes a transgene encoding a heterologous polypeptide conferring on plant expressing said polypeptide resistance to a hemipteroid sap-sucking insect. The transgene is also expressed in a plant component (such as a leaf). Typically, expression of such polypeptides deters feeding by insects such as psyllids (such as an Asian citrus psyllid, the African citrus psyllid, or the American citrus psyllid). Exemplary plants useful in the invention are citrus or solanaceous plants. 本发明涉及包括编码异源多肽的转基因的植物，所述异源多肽对表达所述多肽的植物赋予对半翅类吸汁昆虫的抗性。所述转基因也在植物组分(例如叶)中表达。通常，此类多肽的表达阻止昆虫诸如木虱(诸如亚洲柑橘木虱、非洲柑橘木虱或美洲柑橘木虱)的进食。可用于本发明中的示例性植物是柑橘或茄科植物。
