Efficacy Test of New Attractant for the Yellow-legged Hornet, Vespa velutina (Hymenoptera: Vespidae)

The yellow-legged hornet, Vespa velutina nigrithorax (Hymenoptera: Vespidae), which invaded South Korea in 2003 caused a great damage to honeybee industry. In this study, we tested the efficacy of new attractant and on-the-market-attractant in the apiaries located in Jeonnam area. As the efficacy test result, it turned out that V. velutina was the most dominant species. The newly developed attractant showed substantially high capture of V. velutina that was statistically supported (P < 0.01). On the other hand, many other insects have also been caught by the attractant, requiring further development aimed specific to V. velutina.
