由于本区旱改水面积的扩大、水稻单产的提高、稻田生态系营养和温湿条件的改善,近年来劳氏粘虫Mythimna lorgi(Dup.)对水稻的为害趋向加重。1983～1985年,我们对其发生规律和影响发生因素进行了研究。

In recent years, Mythimna lorgi (Dup.), An armyworm, has become more and more damaging to rice due to the expansion of drought-relief water area, the improvement of rice yield, the nutrition of paddy ecosystem and the improvement of temperature and humidity. From 1983 to 1985, we conducted a study on the occurrence and the factors that affected the occurrence.
