蛴螬是甜菜产区主要地下害虫。苗期咬食幼苗根部,致使幼苗死亡,造成缺苗断垄,甚至毁种。经鉴定大庆地区危害甜菜的蛴螬主要是大黑鳃金龟子(Holotrichiaspp)。自50年代初至1982年对其防治一直应用有机氯农药666,曾获得明显的防治效果,平均保苗率达96.7％。1983年国家停止生产并禁止使用666。1984年提出用辛硫磷代替666防治地下害虫,但由于甜菜对辛硫磷较敏感,易产生药害,限制了其使用。近年来大都采 Scallions are the major underground pests in beet production areas. Seeding seedling seedling root, resulting in seedling death, resulting in missing seedlings broken ridge, and even destroyed species. It has been identified that the beetles that harm beet in Daqing are mainly Holotrichiaspp. Since the early 1950s to 1982, the organochloric pesticide 666 has been used for its prevention and control. It has obtained obvious prevention and cure effects, with an average seedling protection rate of 96.7%. In 1983, the state stopped production and banned the use of 666. In 1984, phoxim was used instead of 666 to control underground pests, but sugar beet is more susceptible to phoxim and is more susceptible to phoxim and limits its use. Most mining in recent years
