鑑別特徵描述:

  體長2.5-3.0 mm，約為體寬之2.5-3倍，圓柱狀，為竹蠹科中體型較小的種類。體色紅褐色至黑褐色。觸角十節，末端三節膨大。前胸背板較大、略呈球狀，前緣較圓突；基部中央具一對較深的卵圓形凹窩，兩凹窩僅被一條很窄的中線分隔。翅鞘為大小一致、不成列的點刻佈滿，末端形成弧狀下降，截面不明顯。

攝食策略:

成蟲在伐倒木、新剝皮的原木和濕板材上鑽圓形深約5mm的侵入孔，然後順年輪方向開鑿長約15-20cm的母坑道，隨即將蛀屑推出坑道。雌蟲產卵於母坑道壁的小室中，並一直守衛在母坑道中直到死亡。幼蟲坑道甚密，縱向排列，充塞粉狀排泄物；深約1. 5cm，最深3cm，全長約10-15cm。新成蟲羽化後就地補充營養，蛀出若干小孔，排出大量蛀屑，被害木材僅留一層薄外皮，一觸即破。

關係:

Miwa (1943)曾記錄此種為柑橘樹(Citrus sp.)、棉花(Gossypium arboreum L.)的害蟲。中國則曾記錄油茶(Camellia oleifera Abel)、櫟屬(Quercus sp.)、辣椒(Capsicum annuum L.)為其寄主。在日本，則記錄此種成蟲、若蟲取食苦楝(Melia azedarach L.)；另一筆記錄則是在苧麻(Boehmeria nivea (L.))上發現。筆者所檢視的標本中，係友人侯舜為先生在馬拉巴櫟(Pachira macrocarpa (Schltdl. & Cham.) Walp.)上採得一隻雌性個體。

Diaphorina citri is an important vector transmitting Candidatus Liberibacter asiaticus (Las), the phloem-limited bacterium that causes huanglongbing (HLB) disease in citrus. Experiments by Mann et al. (2012) suggest that Las influences host selection behavior by D. citri by modifying the release of specific volatiles and plant nutritional contents, facilitating the spread of Las. While increased preference of insect vectors for virus-infected versus non-infected host plants has been demonstrated for both persistently and non-persistently transmitted viruses, little is known about similar interactions involving pathogenic bacteria.
