摘要
金针虫是郑州市农田的主要地下害虫之一,近年来其虫口密度上升,局部地区发生严重,造成小麦、玉米缺苗断垄。分析表明,冬春气温升高、食源充足、秸秆还田面积增大、高毒农药限用以及土壤药剂处理面积减少等是造成郑州市近年来金针虫上升的主要原因。另外,提出了在做好虫情预测预报的前提下,以农业防治为基础,优先采用物理防治和生物防治措施,科学采用化学防治措施的综合防控策略。
As one of the major destructive soil-inhabiting insect pests in Zhengzhou,Henan province,China,the population density of wire worm has increased in recent years with serious damage locally,which causes sprout deficiency of wheat and maize.Analyses indicated that warming climate in winter and spring,abundant food,increasing areas of composting of crop straws,forbidding or limiting of highly-toxic and severe toxic pesticides,and reduction of soil treatment area were main reasons leading to the increasing damage of wire worm in recent years.On the basis of forecasting and agricultural control,the comprehensive strategies including priority utilization of physical and biological control technologies,and scientific usage of chemical control technology were proposed for control of wire worm.
