| 摘 要： | 2012年6月下旬和9月中旬，对吉林省二代和三代粘虫发生严重的辽源、公主岭、梨树、双辽、长岭、农安6个县（市）玉米田粘虫危害情况和产量损失情况进行调查。结果表明，二代和三代粘虫对玉米叶片危害较大，但二代粘虫危害对后期产量影响相对较轻，三代粘虫暴发流行对玉米产量造成损失较大，受害玉米子粒不饱满，果穗短而细，秃尖程度严重，三代粘虫危害产量损失率为25.79%～73.84%。

| Abstract: | 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 degree 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. |
