We selected the trap plant that could attract Ricania spp. adult effectively and the systemic chemicals that could beused at the same time in 2016. Ricania spp. has recently spread throughout Chungnam province since its occurrence in2010. We found that sunflowers could attract them effectively in pre-oviposition period of Ricania spp. and selected thesystemic chemicals could be used with sunflower simultaneously. The sunflower attracted their adults about 90 to 95percent in pre-oviposition period. The systemic chemicals was dinotefuran SG 50% and the control effect of it was 96.2%.The control effect of dinotefuran transferred to sunflower was excellent, and the density of adult in blackberry field couldbe kept low in pre-poviposion period of Ricania spp. The above results show the possibility of using sunflower as atrap plant to control Ricania spp. adults.
