<p><i>Aromia bungii</i> is an invasive wood-boring beetle that creates planned adult emergence holes (PAEHs) prior to reaching the pupal stage, likely due to the limited boring ability of adults. Targeting PAEHs has been proposed as a physical control method, but its effectiveness under field conditions remains untested. We conducted laboratory and manipulation experiments to evaluate the ability of adhesive materials to seal PAEHs, ultimately selecting an epoxy-based adhesive with high blocking performance. A field trial on infested cherry trees showed that sealing visually identifiable PAEHs significantly reduced adult emergence compared to unsealed controls. These findings provide the first empirical support for sealing PAEHs as a non-chemical method to suppress <i>A. bungii</i> adult emergence. This technique represents a promising strategy for integrated pest management strategies. However, emergence from previously undetected PAEHs indicated that relying solely on visual detection is insufficient. Future research should focus on improving the accuracy of PAEH detection, refining adhesive application protocols, and integrating this method with other complementary control tools for more effective and sustainable management of this invasive pest.</p>
