The Asian citrus psyllid (ACP) Diaphorina citri (Hemiptera:Liviidae), vector of huanglongbing disease, displays a high degree of color polyphenism. In the adult stage, ACP exhibits abdominal colors that can be separated into three color groupings: blue-green, grey-brown and orange-yellow. Color morphology has been shown to influence important and energetically costly psyllid life traits including reproduction, dispersion, immune defense and resistance to insecticides. Despite this, it remains unclear how color morphology is correlated with feeding behavior. Understanding variation in feeding behavior of the ACP color morphs is critical to better understanding how ACP populations utilize host-plants and to assess potential risk for transmission of the causal agent of huanglongbing disease. We compared the feeding behavior of the three ACP color morphs by using electropenetrography (EPG). We did not detect differences in the feeding behavior activities at phloem or xylem tissues when comparing the three-color morphs. Furthermore, there were no differences in feeding behavioral parameters before reaching phloem or xylem tissues. Our results suggest energy requirements are similar between color morphs and feeding behavior parameters associated with CLas transmission are potentially similar between color morphs.

亚洲柑橘木虱 (ACP) Diaphorina citri（半翅目：Liviidae），黄龙病病媒，表现出高度的颜色多态性。在成年阶段，ACP 呈现出腹部颜色，可分为三种颜色组：蓝绿色、灰棕色和橙黄色。颜色形态已被证明会影响重要且耗能巨大的木虱生命特征，包括繁殖、分散、免疫防御和对杀虫剂的抗性。尽管如此，目前尚不清楚颜色形态如何与摄食行为相关联。了解 ACP 颜色形态的摄食行为变化对于更好地了解 ACP 种群如何利用宿主植物和评估黄龙病病原体传播的潜在风险至关重要。我们通过使用电子渗透描记术 (EPG) 比较了三种 ACP 颜色变形的进料行为。在比较三色形态时，我们没有检测到韧皮部或木质部组织的摄食行为活动的差异。此外，在到达韧皮部或木质部组织之前，摄食行为参数没有差异。我们的结果表明，颜色变形和摄食行为参数之间的能量需求相似C Las 传输在颜色变形之间可能相似。
