草地螟是我国北、东北和西北地区农牧业生产的重要害虫。自新中国成立以来已经3次暴发成灾,成灾年份已达23年,给我国农牧业生产造成了巨大的经济损失。草地螟的生活史及发生危害规律十分复杂,具有杂(广)食性、迁飞性、群居性、隐蔽性及暴发性等特点,同时大都发生在地广人稀的老少边穷地区,再加上我国对草地螟的发生危害规律了解甚少,无论是对其种群动态规律还是成灾的环境特征均不清楚,因此,监测和预测预报工作十分困难,在防治上十分被动。为了更好地阐明草地螟的发生危害规律,提高草地螟预测、防治工作的主动性,减少草地螟的灾害损失,笔者在总结分析我国
Meadow borer is an important pest of agriculture and animal husbandry in North, Northeast and Northwest China. Since the founding of New China, three outbreaks have taken place in the past and the disaster years have reached 23 years, causing enormous economic losses to the production of agriculture and animal husbandry in our country. Grasshopper life history and the occurrence of hazardous laws is very complicated, with hybrid (wide food), migratory, gregariousness, concealment and outbreaks and other characteristics, mostly in the vast and sparsely populated areas of young and old, plus However, little is known about the occurrence and damage laws of Meadow Stem Borer in our country. It is not clear whether its population dynamics or the environmental characteristics of a disaster occurred. Therefore, monitoring and forecasting work are very difficult and very passive in prevention and control. In order to better clarify the law of occurrence and damage of Meadow Stem Borer, improve the prediction of Stem Borer, the initiative of prevention and cure, and reduce the disaster loss of Meadow Stem Borer,
