Water submergence of infested cherry wood prevents adult emergence of Aromia bungii (Coleoptera: Cerambycidae)

Aromia bungii (Faldermann) (Coleoptera: Cerambycidae) is an invasive wood-boring pest that causes severe damage to rosaceous trees. Controlling this species is challenging because larvae, pupae, and newly emerged adults develop entirely within host wood. Therefore, although proper disposal of infested wood represents a critical management component, conventional methods, such as chipping or burning, are labor-intensive and expensive. Conversely, water submergence may provide a simpler alternative; however, its effectiveness has not been fully evaluated. In this study, infested cherry wood was submerged to assess the impact on insect survival and adult emergence. Adult emergence was observed only in the control; no adults emerged from the submerged wood. Subsequent wood dissection revealed that no live individuals survived the submergence treatment. These results demonstrate that wood submergence effectively prevents the adult emergence of A. bungii and may be effective for targeting individuals developing within the host wood, offering a supplementary approach for preventing the spread of this pest.
