The environmental friendly control of Platypus koryoensis (Murayama), a vector of oak wilt disease, was investigated using citral. To develop an effective attracted trap was performed in Yeoju (semi-field), Gunpo (field) and Cheongju (field). Using a ratio of four attractant (ethanol 100%, ethanol+citral (90:10, 95:5), ethanol+citral+hexane extract of Quercus mongolica (90:5:5)) was investigated attractive effects for the Platypus koryoensis. Most P. koryoensis were attracted to mixture of ethanol+citral (95:5). As a result, when using a citral in a certain concentration is would be able to develop an effective and environmental friendly control agent.
