Abstract An environmentally friendly control strategy for the ambrosia beetle Platypus koryoensis (Murayama), a vector of oak wilt disease, was investigated using the citral as a pheromone component. To develop an effective attractant trap, a semi‐field experiment (Yeoju) and a field experiment (Gunpo) were performed. Different ratios of four different attractant mixtures (ethanol 100 %, ethanol + citral (90:10, 95:5), ethanol + citral + hexane extract of Quercus mongolica (90:5:5)) were investigated to determine their effects on P. koryoensis . The 95:5 mixture of ethanol + citral had the greatest attractant effect on P. koryoensis . However, other ambrosia beetle species did not exhibit a specific response to citral. Our findings indicate that the pheromone citral was effective at attracting P. koryoensis and that certain concentrations of citral could be used to develop an effective and environmentally friendly control agent.
