The survey of yield loss and damaged condition in corn was carried out in 6 locales including Liaoyuan, Gongzhuling, Lishu, Nong’an, Shuangliao, and Changling county, Jilin Province in mid-June and mid-September 2012, which were caused by 2nd-generation and 3rd-generation larvae of oriental armyworm Mythimna separata. Investigation indicated that M. separata damage can cause obvious yield loss. The damaged de-gree by 2nd-generation larvae of oriental armyworm was less than 3rd-generation's. The 3rd-generation larvae can cause heavy damage in yield loss. corn cob showed apparent changes, such as empty grain, less length, slim and no seed on the top of cob. The yield loss rate of corn was between 25.79%and 73.84%caused by 3rd-generation larvae of oriental armyworm.
