The citrus flatid planthopper, Metcalfa pruinosa is one of the invasive insect species in South Korea. M. pruinosa is a broad polyphage damaging over 200 plant species including ginseng, although there is a difference in preference. We selected six insecticides that showed high mortality in ginseng field such as emamectin benzoate EC, sulfoxaflor SG, etofenprox EW, cypermethrin EC, thiacloprid SC and pyrifluquinazon SG. In addition, a method to attract and kill M. pruinosa by treating pesticides on attractive plants (e.g., corn, perilla) with high preference was also tested. The control effect varied from 10 to 80% depending on the distance between forest and farmland. These methods can be used for the control of M. pruinosa in the ginseng farm when the PLS (Positive List System) is fully implemented in 2019.
