建国以来,防治地下害虫的工作取得了很大成绩,基本控制了蝼蛄、金针虫的为害。随着农业生产条件的改善,耕作制度的改革,农业生态系发生了变化,某些方面有利于蛴螬的发生、繁殖;而原有的防治方法,不适应于目前虫情的发展,未能收到最大的防治效果。近年来,旱粮地区地下害虫总的发生趋势是:蝼蛄下降;金针虫局部严重;蛴螬明显上升,为害多种作物,尤以花生、大豆等受害最重。据此情况,提出下列几点要求: Since the founding of the People’s Republic of China, great achievements have been made in the prevention and control of underground pests, basically controlling the scabies and insects. With the improvement of agricultural production conditions and the reform of the farming system, the agro-ecosystems have undergone changes and some aspects are conducive to the occurrence and reproduction of the catfish. However, the original methods of prevention and control are not suitable for the current development of the insect and can not be collected To the maximum control effect. In recent years, the general trend of underground pests in dry-land areas is as follows: 蝼 蛄 declines; the locusts are severely grazed; 蛴 螬 significantly increased and harmed many crops, especially peanuts and soybeans. According to this situation, the following requirements are proposed:
