Recently, Metcalfa pruinosa is the pest that can not be easily controlled due to its wide host range. Therefore, it seems necessary to develop a trap plant that can block the entry of M. pruinosa into the farm. We have examined the host preference of M. pruinosa in previous studies and verified their attractiveness to these pests for some favored plants(bean, perilla, sunflower and sesame). We divided the plants used in the experiment into young and maturing stages. In the yougn stage of the plant, the soybeans were highly suscetible to M. pruinosa, but the sunflower was the most influential in the mature stage. Therefore, we selected sunflower as a trap plant to M. pruinosa and conducted a field survey. The sunflower attracted effectivley M. pruinosa in aronia cultivation system. But the time of our experiments was at the nymphal stages of M. pruinosa and at the beginning of adult emergence. Therefore, we plan to conduct experiments at the peak period of adult emergence and develop the trap with attractants.

Metcalfa pruinosa is the agricultural pest, first reported in Seoul, Gyeong-gi, Gyeongnam, Korea in 2009. This pests are difficult to control due to the wide range of hosts such as beans, apples, ginseng, pears, persimmon, and peaches. This study was carried out to investigate the ecological characteristics of M. pruinosa in pepper cultivation area. As a result of the density of M. pruinosa survey in Chungnam, Korea in 2018, the density of wintering-eggs, nymph, adult was the largest in Dang-jin area. And the results of the ecological characteristcs survey of M. pruinosa in red pepper cultivation area of Korea, M. pruinosa didn’t enter a red pepper field. In addition, the possibility of using three kinds of plants as attraction plants was examined in order to control environmentally friendly M. pruinosa. Among them, the greatest number of M. pruinosa nymph were attracted to Sunflower and Green perilla during nymph stage.
