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.

本发明涉及一种植物，该植物携带有编码异源多肽的转基因（transgene），该异源多肽可赋予表达该多肽的植物对半翅目刺吸式昆虫的抗性。该转基因亦可在植物组织（如叶片）中表达。通常，这类多肽的表达可驱避木虱类昆虫（如亚洲柑橘木虱、非洲柑橘木虱或美洲柑橘木虱）的取食行为。本发明所适用的示例性植物包括柑橘类植物或茄科（solanaceous）植物。
