To identify the host plants of Pochazia shantungensis (Chou & Lu, 1977), this study investigated plant species showing egg-laying scars of P. shantungensis in fruit orchards, public parks, home gardens, and streets in northern Wakayama Prefecture. A total of 85 plant species belonging to 41 families, including fruit, ornamental and street trees, were found to be oviposited on by this species. Among fruit trees, the number of egg-laying scars was relatively high on Japanese apricot, peach, plum, citrus species, sansho, persimmon, blueberry, and pawpaw.
